Claude Code Changelog

2.1.306

Tue, 20 Oct 2026 16:00:00 GMT

Fixed claude -p inside cloud sessions reporting “Not logged in” when started without the session’s environment variables
Fixed an API error being replaced by “prompt is too long”, and an unneeded compaction, in sessions with many MCP tools

2.1.305

Mon, 19 Oct 2026 16:00:00 GMT

Added

Added sandbox.allowNestedUserNamespaces so sandboxed commands on Linux can create user namespaces (Chromium, rootless podman); this lets them get around the sandbox’s file protections
Added CLAUDE_CODE_RETRY_WATCHDOG_USAGE_LIMIT_RECHECK_MS so unattended retry mode (CLAUDE_CODE_RETRY_WATCHDOG) notices a usage limit that was lifted before its reset
[VSCode] Added a “Running start-up hooks” spinner status, with a screen reader announcement, while SessionStart or Setup hooks run
[Claude Tag] Added public Slack channels Claude hasn’t joined to the Claude Tag admin Add place search, so admins can set one up from there

Changed

Changed allowedMcpServers to stop filtering managed-mcp.json stdio servers that use ${VAR} only in env: one your allowlist left out now loads on upgrade; use deniedMcpServers to keep it off
Changed plugins that Claude Desktop mounts by path to no longer keep their allowed-tools when your organization’s managed settings set allowManagedPermissionRulesOnly
Changed the /artifacts delete confirmation to take 1 or Enter to keep, 2 to delete, and Esc to cancel; y and n no longer answer it
Changed a mod’s docked pane to stay within 45% of the terminal’s width, including a width kept from a wider terminal
[VSCode] Changed the message shown when a session does not start in time and no hook is running: it now leads with the output logs and lists causes instead of pointing to sign-in and network first
[Code Review] Changed Code Review re-reviews so they no longer open with LGTM while earlier blocking findings are still open

Show 6 improvements

Improved /usage: each warning is now a one-line fix that names its source, and f applies the fixes; the same fixes appear in VS Code and /doctor
Improved MCP consent dialogs so an Enter meant for the prompt is less likely to be taken as Accept
Improved a mod’s Image to draw its picture in iTerm2 3.5 and later with fullscreen rendering, where it showed only its alt text
Remote Control: Improved the spawn-mode messages: pressing w now says the new mode is saved for the folder, and a later claude remote-control start that uses the saved mode says where it came from
[Cloud sessions] Improved deleting a self-hosted environment so the dialog and error messages say what blocks the delete and what it will affect
[Claude Tag] Improved Claude Tag admin pages in large organizations so plugin, skill and bundle edits work while the channel list is still loading

Show 22 bug fixes

Fixed every request failing on Vertex, Bedrock and other providers when the endpoint or a gateway rejects tool search, and behind gateways with ToolSearch disallowed or left out of --tools (a 2.1.304 regression): Claude Code now retries without it
Fixed /effort and /autocompact settings not applying when the model name differed from a modelOverrides value by letter case or a [1m] tag
Fixed new worktrees in a bare repository sometimes starting from local HEAD instead of the default branch, and unchanged subagent worktrees sometimes not being cleaned up
Fixed Bash commands on a full disk failing with a raw ENOSPC file path: the error now says the disk is full and that nothing ran
Fixed an MCP server passed by a cloud session or by the SDK’s setMcpServers being replaced later in the session by a same-named server from your own settings
Fixed Claude naming the wrong model for a subagent’s work after the subagent switched to a fallback model
Fixed cloud sessions and teammates not telling Claude when a compaction had to leave the oldest messages out of its summary to fit
Fixed more cases of scheduled Cowork cloud sessions waiting five minutes for each subagent whose WebFetch needed a URL approval that nobody was there to give
Fixed Workflow resume re-running already-completed pipeline() and parallel() agents instead of serving them from the run’s journal
Fixed Remote Control leaving empty “(session)” entries in /resume after switching conversations with /resume
Fixed /usage rows being cut off in narrow terminals
Fixed startup warnings printing as raw text above the logo: they now go to the debug log, and permission rules that restrict nothing show as warning rows under the banner
Fixed screen reader mode: search boxes now say “Search:” instead of a symbol VoiceOver read as “telephone recorder”, and highlighted prompt text, such as Ctrl+R search matches and “ultrathink”, no longer has spaces inside words
Self-hosted runner: Fixed a start script that shares only its stdout with the runner or orchestrator failing with Resource temporarily unavailable when TERM is set (a 2.1.300 regression)
Self-hosted runner: Fixed repository access failing since 2.1.296 when a git credential helper or askpass program reads its settings through GIT_CONFIG
Self-hosted runner: Fixed the orchestrator reporting a spawn-runner hook as timed out when a runner it started in the background kept its output open
[VSCode] Fixed the spinner cutting off “Compacting…” when your spinnerVerbs setting replaces the built-in verbs with short ones
[Cloud sessions] Fixed the Cloud environments admin page wrongly refusing to save an existing environment with an “installs packages” error
[Claude Tag] Fixed Claude Tag access bundles so a repository that moved to another GitHub account can be added again
[Claude Tag] Fixed a routine set up in a Slack DM thread no longer posting after another routine in that thread restarted the conversation; both now keep posting there
[Claude Tag] Fixed routines set up in a Slack thread reporting success without posting after the conversation ended; those runs are now skipped and the creator is told
[Code Review] Fixed Code Review sometimes not reviewing the newest commit when several pushes landed on a pull request during a review

2.1.304

Sun, 18 Oct 2026 16:00:00 GMT

Added

Added a transcript line when a plugin that runs first skips one of your mod’s hooks, naming the event and the plugin
Added decider: "person" to a mod’s tool.check answer: only the permission dialog or a host’s callback can approve the ask, and it is refused with the mod’s reason where nobody can be asked
Added e.isReadOnly to a mod’s tool.check event, set when the tool call is read-only
Added /auto-mode-setup: a guided setup that reads your project and recent sessions to teach auto mode about your environment, now also available on Bedrock, Vertex, Foundry, Claude apps gateway and telemetry-disabled sessions
Added /claude-api managed-agents-secure, which compares a Managed Agents agent’s settings with Anthropic’s published security guide, without changing anything
Added the names of the tools called earlier to the compaction summary in the transcript view (Ctrl+O)
Added a warning on Pro and Max plans when resuming an inactive conversation would use a noticeable share of your 5-hour usage limit: resume anyway, or start a new conversation and Claude can look up the previous one if you refer to it
[VSCode] Added mod drawing in the chat panel for sessions on Amazon Bedrock, Google Vertex AI and Microsoft Foundry, behind an LLM gateway, or with telemetry turned off
[Code Review] Added review levels to Code Review: Owners choose Quick, Standard (the default), or Deep for the organization, and can give individual repositories their own level
[Code Review] Added an option in Code Review admin settings to review every repository in a GitHub organization, including ones added later, without selecting them one by one

Changed

Changed mods’ settings.read hooks to receive each settings layer and rewrite the merged settings, so a managed mod can make an organization’s setting a ceiling, including the cleanupPeriodDays the retention sweep uses
Changed the /artifacts delete confirmation to show numbered choices: 1 or Enter keeps the artifact, 2 deletes it, and y, n and Esc still work
Changed the question that turns on the mods Claude writes in a session to plain text with no link or session id; it stays up when a new turn starts, and Claude tells you what loaded when you turn them on
Changed tool search to be on by default behind a custom ANTHROPIC_BASE_URL; a 400 or 422 from the gateway is retried without it
Changed compaction to send Claude the skill list again afterwards; /reload-skills now sends only new or changed skills
Changed skill hooks: the skills of one source (a repo, your own folder, or a plugin) can register at most 1,024 hooks and 16,384 matcher characters per session
Changed skills under a policy that allows hooks from plugins only: a skill used in the main conversation whose hooks are kept out no longer gets its allowed-tools
Updated the /claude-api skill to use the ant CLI on Claude Platform on AWS instead of falling back to the SDK or curl
Removed the notes from claude plugin validate that predicted where a mod’s hooks would run
Removed the “(research preview)” label from the /fast dialog title on Opus 5.5
[VSCode] Changed background sub-agents to show as one status line under their Agent card instead of streaming every step into the chat; the full transcript stays in /tasks

Show 12 improvements

Improved /usage to say when a rate limit on usage data ends instead of “try again in a moment”
Improved the lines shown when a mod written in the session loads, reloads or fails to load
Improved artifacts with several views: when you ask for links to them, Claude now writes out each view’s link and explains that the address bar stays the same as you switch views
Improved cloud sessions: a new conversation’s first turn no longer waits for the local (stdio) MCP servers of plugins synced from claude.ai, unless a server sets alwaysLoad: true
Improved how a remote session recovers its status when the server refuses a status update that carried other session data
Improved session file size in auto mode: the safety classifier’s context is no longer stored with every request
Improved the claude -p invalid-settings warning: a file that did not load lists only what stopped it, and long lists are capped per file
Improved resume of large compacted sessions in SDK and headless mode: the first request after resuming is sent sooner
Improved responsiveness and throughput when many subagents are running at the same time
Improved memory use when sending requests in long or resumed conversations
Self-hosted runner: Improved the error shown when the git host answers “not found” for a session’s repository: it now names the repository and whom to ask
Windows: Improved git command start-up with a standard Git for Windows install by running its git.exe directly instead of through its cmd launcher

Show 43 bug fixes

Fixed the organization policy not refreshing until the hourly check after approving an ANTHROPIC_API_KEY at startup or switching “Use custom API key” in /config
Fixed sandboxed commands failing to start on Linux when a sandbox.filesystem.denyRead glob contains brackets that are not a character class, such as a [user-id] route folder
Fixed rm -r of a mounted drive or a folder at its top level (/Volumes, /media, WSL’s /mnt/c) not getting the safety prompt that rm -rf /Applications gets
Fixed CLAUDE_CODE_TRANSCRIPT_LOCAL_GC dropping messages from the saved transcript when the disk filled up while the file was being trimmed
Fixed a plugin keeping a headless run going past --max-turns, Stop, or ended input by spawning subagents or re-running a finished one
Fixed a failed mod reload removing the tools and commands of the version that stays loaded, and its messages being wrong or silent about whether the previous version is still loaded
Fixed a click on a mod’s button being lost when buttons with the same label and no key were redrawn unchanged
Fixed mod sharing in the built-in plugin-authoring skill stopping at the secret scan on machines with managed settings and on Team and Enterprise plans
Fixed scheduled Cowork cloud sessions waiting five minutes again for each subagent whose WebFetch needed a URL approval that nobody was there to give
Fixed Write results and rejected edits showing a file outside the working directory as ../../…; they now show ~/… or the full path
Fixed a claude.ai Directory plugin’s skills not running as commands when picked from the ”/” menu in Cowork cloud sessions
Fixed Remote Control permanently withholding a desktop conversation’s history when a different account was signed in to the terminal
Fixed Remote Control failing to start from Claude Desktop when DISABLE_TELEMETRY or DO_NOT_TRACK is set on a paid plan
Fixed model switches, messages and interrupts waiting behind a context usage check in SDK and desktop sessions
Fixed context_management: Extra inputs are not permitted errors behind LLM gateways; Claude Code now resends the request without that field
Fixed OpenTelemetry settings delivered through server-managed settings being ignored for the whole session after signing in during first-run setup or the first start after /logout
Fixed unsandboxed Bash commands in Claude Desktop Code tab sessions on macOS and Linux not seeing environment variables exported in shell startup files such as ~/.zshrc
Fixed the Consumer Terms notice being skipped for a day or longer after a server error
Fixed /privacy-settings offering choices that may not apply to you after a network or server error
Fixed a “Context limit reached” or “Prompt is too long” error after stopping a turn while Claude Code was compacting a conversation the API had rejected as too long
Fixed subagents sometimes forgetting their most recent work when they were messaged or resumed right after finishing
Fixed claude --help text for --tools, --resume, --debug, --json-schema, --disable-slash-commands, --system-prompt-snapshot and claude update to match actual behavior
Fixed claude --worktree removing the worktree and its branch without asking at exit when HEAD was detached or on another branch, which could lose commits
Fixed resumed and cloud sessions sending Claude the whole skill list again each time plugins reloaded at startup
Fixed an interrupt not ending a Read that waits on an idle pipe or device named like an image
Fixed /effort status, /effort ultracode and the prompt’s effort indicator showing a guessed effort level when CLAUDE_CODE_EFFORT_LEVEL is auto or unset and no level is sent
Fixed a PreToolUse hook’s deny reason being replaced by a timeout error when an Agent SDK callback hook on the same tool call timed out
Fixed Bash and PowerShell deleting a large command’s output file when it could not be copied to the session’s tool-results folder, unless the disk is full
Fixed notes typed into a multiple-choice question with previews being cut off with ”…” in terminals under about 100 columns, hiding what was typed (anthropics/claude-code#82768)
Fixed self-paced /loop wakeups scheduled at the 1-hour maximum firing just after the 1-hour prompt cache expired, so those wakeups no longer re-read the conversation uncached
Fixed agent teams: approving a shutdown request from the main session no longer exits the whole CLI
Fixed a skill’s once hook also removing another skill’s identical hook after it ran
Fixed transcript mode’s { and } landing the prompt on an inconsistent row, or off screen, instead of the transcript’s first row
Fixed CLAUDE_CODE_AUTO_COMPACT_WINDOW=200k silently setting a 100K window: the variable now accepts k and M suffixes like --autocompact, and warns when a value is out of range or ignored
Fixed Ctrl+C in the agents view clearing a text selection without copying it when pressed before the mouse button was released
[VSCode] Fixed one cause of sessions failing to start with “Subprocess initialization did not complete within 60000ms”: time a SessionStart command hook spends running no longer counts toward the limit, up to 10 minutes in total
[VSCode] Fixed a session closed while it was starting keeping its Claude Code process running until the start ended
[VSCode] Fixed a mod’s drawings disappearing from a long-open panel until the next turn on machines that also run an older Claude Code
[VSCode] Fixed Past conversations hiding sessions when claudeCode.claudeProcessWrapper is set
[Cloud sessions] Fixed folders in the composer’s @ list showing no name in cloud sessions, where picking one added only a space instead of a mention
[Claude Tag] Fixed Claude going silent in a thread when its channel becomes shared across Enterprise Grid workspaces mid-task; it now posts a one-time note to @-mention it in a new thread
[Claude Tag] Fixed @Claude !fork typed outside a thread getting no visible reply; Claude now shows you a private note saying to run it from inside a thread
[Code Review] Fixed pull requests opened within a minute or two of an admin turning on Code Review being silently skipped; they are now retried and reviewed

2.1.303

Sat, 17 Oct 2026 16:00:00 GMT

Bug fixes and reliability improvements

2.1.302

Thu, 15 Oct 2026 16:00:00 GMT

Added

Added CLAUDE_CODE_AUTO_MODE_MODEL to choose the model the client-side auto mode classifier uses; it does not change the model for server-side auto mode
Added an Idle compaction row to /config for turning idle compaction off or back on; the notices shown after an idle compaction now say how to turn it off
Added a notice to /design-sync and /design-login that standalone Claude Design (claude.ai/design) closes by December 14, 2026
[Cloud sessions] Added a banner on a routine’s page that says why its last run didn’t start, such as your organization reaching its limit on concurrent cloud sessions

Changed

Changed claude -p and Agent SDK sessions with no permission mode to start in default mode on third-party providers, with telemetry off or on a fresh install; --permission-mode auto keeps auto
Changed fork subagents (subagent_type: "fork") to be on by default in claude -p, the Agent SDK, the desktop app and VS Code, as they already are in the terminal; CLAUDE_CODE_FORK_SUBAGENT=0 turns them off, and claude mcp serve never offers them
Changed the desktop app and VS Code to always run the main conversation’s subagents in the background, as the terminal does, rather than let Claude choose; a subagent’s own Agent calls in claude -p, the Agent SDK, the desktop app and VS Code now run in the foreground by default
Changed the ← for agents footer hint to hide 10 seconds after a session opens; the count of agents waiting on you still shows
Changed where the Claude in Chrome instructions sit in the system prompt so that new conversations can read them from the shared prompt cache
Changed prompt and agent hooks so that at most 12 of one event run at a time; the rest wait their turn
Changed the message shown when your organization’s policy turns off /feedback: it now points to GitHub issues instead of an organization admin
[Claude Tag] Changed Claude Tag admin settings to organize Claude’s access into four tabs: Bundles, Connectors, Skills and plugins, and Channels
[Claude Tag] Changed the Roles page in organization settings to group the roles created for Claude Tag channel managers in a collapsed section below your organization’s own roles

Show 7 improvements

Improved startup time with many plugins enabled: plugin command and agent files now take far fewer file system calls to load, most of all on Windows
Improved auto mode with the server-side classifier: a conversation too long for the safety check is now compacted, instead of every checked tool call being denied
Improved the message when a background session reopened from another folder has no LLM gateway: it now says why, instead of “Not logged in”
[Cloud sessions] Improved the error shown when a cloud session fails to start: it now says “Connection lost” or “Server error” instead of “Something went wrong”
[Claude Tag] Improved repository search in Claude Tag admin settings to cover up to 100 connected GitHub accounts and find private repositories past the first 5,000 of a GitHub App install
[Claude Tag] Improved Add place in Claude Tag admin settings to list a channel you type or paste right away, instead of only after your organization’s full channel list has loaded
[Claude Tag] Improved Add > Domain on a workspace’s or channel’s page in Claude Tag admin settings to be available once that page loads, not only after every channel has loaded

Show 43 bug fixes

Fixed a “Prompt is too long” error when stopping a turn while the conversation was being compacted
Fixed requests failing with “diagnostics: Extra inputs are not permitted” after switching to Vertex or Bedrock mid-session
Fixed the Read tool loading an image file of any size, or a pipe or device named like an image, entirely into memory; image sources over 128 MB are now refused
Fixed /autocompact and /effort saving to the wrong model when a gateway names Opus 4 or 4.1 with a prefix, such as anthropic/claude-opus-4-1
Fixed a prompt cache miss when a tool added mid-session was loaded again through ToolSearch or after compaction
Fixed claude plugin and other subcommands sometimes exiting before a queued settings or config write finished, which could lose the change or leave a .tmp file behind
Fixed plugin marketplaces re-cloning on every refresh, and newly installed git plugins showing version “unknown”, when git defaults to the reftable ref format
Fixed the PowerShell tool not finding commands in a plugin’s bin/ folder, and reporting an error when a search that finds nothing (rg, grep, findstr, git grep) is piped into Select-Object or another formatting cmdlet
Fixed Claude in the desktop app pointing you to claude.ai settings or /mcp to authorize or reconnect an MCP server where that option isn’t available
Fixed artifact publishes sometimes failing when Claude sent an empty list of edits, and Claude retrying an artifact update the wrong way after a newer version of the artifact turned it away
Fixed classifier_category missing from OpenTelemetry tool_decision events for most auto mode classifier blocks, and new tool_decision attributes pushing out tool_use_id, tool_source and tool_parameters when OTEL_LOGRECORD_ATTRIBUTE_COUNT_LIMIT is low
Fixed rows in the agents view staying blank after moving down a long list or folding a section
Fixed claude remote-control --help not printing its usage and exiting when not signed in
Fixed /design consent and /design revoke suggesting /design-login when they fail in a cloud session, where it isn’t available; the message now points to claude.ai/design/settings
Fixed MCP servers showing no tools, or every tool call failing, when the server negotiates protocol version 2026-07-28 but omits resultType, ttlMs or cacheScope
Fixed prompt suggestions spending usage credits on models your plan pays for only with credits: they are now skipped after a reply billed to credits
Fixed URLs written in backticks being clickable only on their first row when they wrap; the whole URL is now one link in terminals that support hyperlinks
Fixed claude plugin details <name>@builtin suggesting claude plugin list, which never shows built-in plugins, when the plugin isn’t found; it now points to /plugin
Fixed an emoji that a link starts inside wrapping one column too wide, which hid it in question previews and turned tables into lists
Fixed worktree isolation refusing to create or resume worktrees under git 2.56 or later when a stray .git file points at a directory that doesn’t exist
Fixed a cloud session’s cost and usage restarting from zero after the session resumed in a new process
Self-hosted runner: Fixed git fetches failing with “bad object refs/heads” in sessions that reuse a checkout stored in git’s reftable format
Windows: Fixed every file write being refused or asked about for projects on exFAT or FAT32 drives, including in sessions started with --plugin-dir
[VSCode] Fixed text after an unclosed code block in a list showing as plain text while a reply streams, then turning into code
[VSCode] Fixed MCP server sign-in from the panel opening a broken authorization page when the server URL contains a query string
[VSCode] Fixed the @browser banner saying “Browser connected” when no browser with the Claude extension can be reached
[Cloud sessions] Fixed “Rewind to here” failing on every message except the newest in cloud sessions; self-hosted runners need Claude Code v2.1.246 or later
[Cloud sessions] Fixed the pull request status bar in cloud sessions flipping a pull request with merge conflicts back to ready while GitHub rechecked it
[Cloud sessions] Fixed routine runs showing as Completed after their cloud session stopped unexpectedly, and as Cancelled when archived before they started, instead of failed
[Cloud sessions] Fixed the diff view in cloud sessions missing changes or failing to load after the session’s GitHub repository was renamed or moved
[Cloud sessions] Fixed a scheduled routine run that failed partway being run again from the start an hour or more later, which could repeat work such as posting the same report twice
[Cloud sessions] Fixed an open cloud session sometimes not showing messages sent from another device until you reloaded the page or clicked away and back
[Remote Control] Fixed a subagent’s pane spinning forever in a Remote Control session after your computer goes offline; it now says Remote Control is disconnected
[Claude Tag] Fixed “is thinking…” staying up under a mention in a Slack channel or DM after Claude answered it by editing one of its earlier messages
[Claude Tag] Fixed URLs in code blocks under a numbered or bulleted step of Claude’s Slack replies being wrapped in angle brackets, which broke copied commands
[Claude Tag] Fixed HEIC, SVG, TIFF and BMP images attached in Slack never reaching Claude; they now arrive as files in its working files, like other file types
[Claude Tag] Fixed new channel managers losing access to Claude in Slack in organizations that restrict Claude Tag by role; the manager role now also grants Claude Tag in Slack
[Claude Tag] Fixed custom connectors whose MCP servers share one host showing as a single connector in Claude Tag admin settings; each server is now its own connector
[Claude Tag] Fixed Claude in Slack sometimes answering a direct message with “DMs are temporarily unavailable” and dropping it when a single Slack lookup stalled; it now retries first
[Claude Tag] Fixed direct messages with Claude on a Slack Enterprise Grid ignoring Slack’s workspace dropdown; they now run under the connected workspace you last opened Claude in
[Claude Tag] Fixed Claude in Slack’s notice for a channel’s monthly spend limit saying a channel manager can raise it; it now names an organization owner and links the usage page
[Claude Tag] Fixed links in Claude’s Slack replies absorbing the closing bold or italic marks, or full-width punctuation, right after them, which broke the link and the formatting
[Code Review] Fixed Code Review setup not resuming after you leave to connect GitHub; back in admin settings, it now reopens at the repository picker

2.1.301

Wed, 14 Oct 2026 16:00:00 GMT

Added

Added CLAUDE_CODE_RETRY_WATCHDOG_MAX_USAGE_LIMIT_WAIT_MS so unattended retry mode (CLAUDE_CODE_RETRY_WATCHDOG) ends a request at a usage limit that resets too far away instead of waiting
Added OpenTelemetry tracing guidance to the claude-api skill, including setting up trace destinations with the ant CLI
Added the % motion to vim mode: jump to the matching bracket, alone or with d/c/y
Added rows to a mod’s Input: a text field of several lines in the terminal, where Enter submits and Shift+Enter or a backslash before Enter starts a new line
Added classifier_verdict and permission_mode to OpenTelemetry tool_decision events, so auto mode classifier decisions can be told apart from permission rules
Added classifier_category to OpenTelemetry tool_decision events, naming the built-in rule a classifier block matched, when OTEL_LOG_TOOL_DETAILS=1
[VSCode] Added LaTeX math rendering in Claude’s responses, including $$ and multi-line \[ … \] blocks and inline $…$ and $…$ math
[VSCode] Added a “Get more usage” link to the usage-limit banner for Pro and Max plans in the VS Code and JetBrains panels

Changed

Changed a mod hook’s .catch handler to run only when the hook throws or times out; events raised beneath the hook’s own calls now skip that hook without asking its .catch
Changed a mod’s $.env.set to resolve with {} once the variable is set or unset, or with { deny } saying why when the write is not made

Improved

Improved switching to a model with a smaller context window: a conversation too long for the new model is now summarized by the previous model first
Improved rendering performance while a long-running subagent works: its progress trail now updates incrementally instead of being reprocessed in full on every render
Improved artifacts: pages Claude writes now paint the band above a sticky header, so scrolled text no longer shows there in the mobile apps
Improved mods: in VS Code and the desktop and mobile apps, a tree drawn above the question dialog can now hold Markdown and up to 48 rows; the terminal keeps 12 plain rows

Show 37 bug fixes

Fixed quitting removing a worktree made by a WorktreeCreate hook without asking when it may hold unpushed commits
Fixed the fable (and best) model alias erroring on the Anthropic API when the newest Fable model is not available to your organization: Claude Code now retries once on the previous Fable model
Fixed a misleading “Please run /login” error when a full disk keeps the login from being refreshed; the error now names the disk and says to delete files
Fixed Grep and Glob reporting no matches when the search program failed unexpectedly before returning any results; they now return an error saying the search failed
Fixed workflow agents sometimes skipping their step, and the run still reporting success, after reading the harness note that their task text carries no user authority
Fixed artifact updates being refused where a PreToolUse hook covers Edit or Write; Claude now edits the file and then republishes instead of changing it in the publish call
Fixed skills and commands with very many or very long argument names stalling for seconds when invoked; only the first 64 names, each up to 64 characters, are now filled in
Fixed skills, commands and hooks using very large amounts of memory when their arguments fill many placeholders
Fixed stray characters such as >0q covering the folder trust prompt, and >4m before the shell prompt at exit, in terminals built on VTE older than 0.53 such as MATE Terminal on RHEL 8
Fixed stray GOK text appearing in the prompt at startup in some versions of iTerm2
Fixed switching to a model whose name contains application-inference-profile running your awsAuthRefresh command and delaying model-switch hooks when the provider is not Bedrock
Fixed sign-in refresh timeouts and unexpected sign-outs after a short command such as claude auth status or claude plugin list exited in the middle of a token refresh
Fixed a tool call cut off by a message sent mid-turn during its permission check being reported to the model as rejected by the user
Fixed a case where switching to a model with a smaller context window could spend usage credits on a summary by the previous model without asking first
Fixed conversations being compacted over and over, on a model you didn’t pick, behind an LLM gateway whose responses name a different model than the one requested
Fixed vim mode sometimes staying in INSERT after Escape on a slow or busy machine
Fixed Esc discarding a typed AskUserQuestion answer in vim mode: the free-text field now supports vim NORMAL mode, and Esc cancels only from NORMAL
Fixed the Read tool reading binary files such as .xlsm, .parquet, .epub and .heic as text
Fixed a Markdown table with only a header row drawing nothing when too wide for the terminal, including in plans on the plan approval card
Fixed the /claude-api skill saying CMEK external-key endpoints aren’t available on Claude Platform on AWS
Fixed skills no longer being listed to the model after using /rewind
Fixed the compaction row in a resumed session offering ctrl+o for history that is not loaded; it now says where the earlier messages are saved, and also shows in fullscreen
Fixed the “new task? /clear to save tokens” hint coming back right after you interrupt a response
Fixed the permission prompt for a plugin or skill hook’s ask decision not showing which plugin or skill the hook comes from
Fixed /diff not noticing a conflicted cherry-pick or revert in reftable repositories when one of its git checks timed out or failed
Fixed workflow scripts asking for permission or being refused when read, edited or re-run after a Bash cd in the same session
Fixed dim text on the dark ANSI theme and 16-color terminals: faint inside filled boxes, not faint under selection and search highlights, and list descriptions dimmed like other secondary text
Fixed a mod’s $.model.fork returning nothing-to-fork when called before the first response of a new Claude Code process had finished, as in claude -p runs and cloud sessions
Fullscreen mode: Fixed /compact and auto-compact briefly freezing the UI while the visible transcript is rebuilt
Self-hosted runner: Fixed sessions started from Slack being unable to find or attach a repository when managed settings restrict MCP servers; use deniedMcpServers to keep those tools off
Self-hosted runner: Fixed sessions being reported as having a deleted source branch, and not retried, when an unrelated setup or session failure quoted git’s missing-ref wording
Self-hosted runner: Fixed the log promising a retry of a failed or declined session release for a session that is ending; repeated failures now show a count
Windows: Fixed stopped background PowerShell commands missing the closing [killed] line in their output file
[VSCode] Fixed a conversation that crashes or freezes the panel being reopened on every reload
[VSCode] Fixed the chat panel slowing down during long thinking: it no longer re-parses the whole thinking text on every update
[VSCode] Fixed diagnostics showing “[object Object]” instead of the rule code (e.g. MD013) for some language servers
[VSCode] Fixed the native dictation audio module being loaded, to check microphone permission, where dictation is not offered (non-claude.ai sign-ins, remote windows)

2.1.300

Tue, 13 Oct 2026 16:00:00 GMT

Added

Added virtualText to a mod’s prompt decorations: text drawn in the prompt box that never enters the draft or the submitted prompt
Added cache_creation_5m_tokens and cache_creation_1h_tokens to the OpenTelemetry api_request event, splitting cache writes by lifetime
Added $.ui.view({ agentId }) for mods: shows an agent’s transcript in the main view when you ask, and $.ui.view({}) goes back
Added a dir prop on a mod’s Text for right-to-left text: on Windows and in VS Code’s terminal its rows read in that direction and sit flush right
Added /advisor on Claude Platform on AWS; no advisor runs until you pick one with /advisor, advisorModel or --advisor, and CLAUDE_CODE_DISABLE_ADVISOR_TOOL=1 turns it off
Added OpenTelemetry GenAI semantic-convention attributes to trace spans, such as gen_ai.provider.name, gen_ai.conversation.id, gen_ai.tool.name and error.type
Added support for rewriting a workflow agent’s prompt and model in the agent.spawn mod hook, which could only refuse workflow agents before
Added the prompt.change mod hook, raised when the prompt box’s text changes without a typed edit: a recalled history entry, a clear, an undo, or a plugin’s fill
[VSCode] Added the claudeCode.attachSelection setting to stop text selected in the editor from being added to your messages
[Claude Tag] Added support for Slack Connect channels: an Owner or Claude Tag admin can let Claude in Slack answer in channels shared with another organization; it’s off by default
[Claude Tag] Added a private Allow once / Deny card in Slack threads for connector actions that need your approval, so Claude asks instead of refusing; others only see that it’s waiting on you
[Claude Tag] Added support for Slack voice clips in Claude in Slack: Claude reads Slack’s transcript of a clip when Slack has one

Changed

Changed CLAUDE_CODE_PROVIDER_MANAGED_BY_HOST sessions to ignore CA-bundle, tool-proxy, git TLS and git config variables like SSL_CERT_FILE in settings; under Claude Desktop, only in project settings
Changed exit to force-kill background commands still running 1.5 seconds after being asked to stop; in fullscreen mode they could previously be left running
Changed Claude Desktop’s Code tab to apply managed settings when forceLoginGatewayUrl names an Anthropic-operated gateway that serves the session’s hostname; that gateway must be reachable at start
Changed claude gateway to stop at start, naming the key, on a desktop: policy key that Claude Desktop cannot use from a gateway, where it earlier started with a warning
Changed large requests to api.anthropic.com to use gzip compression even when telemetry is disabled; set CLAUDE_CODE_GZIP_REQUEST_BODIES=0 to turn it off
Changed the claude-api skill to leave Managed Agents sessions in place unless you ask to archive or delete them
Changed background sessions to resume a carried workflow through the Workflow tool’s approval instead of running it from the handoff file
Changed local session transcripts to also record each API request’s system prompt, tools and parameters, so a transcript you choose to share can reproduce a request exactly
Changed the /sandbox mode options to read “Sandbox commands” instead of “Sandbox BashTool”
Changed PermissionRequest hooks in Cowork cloud sessions: a setMode update in a hook’s allow is now ignored; the rest of the approval still applies
Changed hooks: updatedInput from PreToolUse and PermissionRequest hooks is now validated like Claude’s own input: unknown keys are dropped, and input the tool rejects denies the call
Removed the --sandbox and --no-sandbox flags from claude remote-control, which had no effect; passing either now exits with an error. Set sandbox.enabled in settings to sandbox sessions
[Claude Tag] Changed access bundles an admin attached to a Slack channel to keep applying once the channel becomes a Slack Connect channel, with no need to remove and re-attach them

Improved

Improved WebFetch in Cowork cloud sessions to tell Claude that a page failed moments ago instead of fetching it again
Improved mod sharing in the built-in plugin-authoring skill: Claude scans a mod’s files for keys before opening them, and asks before scanning a folder outside the project
Improved the note Claude 3 models get about an @-mentioned PDF, so they less often answer without reading it
Improved artifact updates: Claude now applies a small change and republishes the artifact in one call, and makes larger edits and republishes within a single response

Show 59 bug fixes

Fixed cloud sessions telling Claude that an organization policy blocked a host when the session’s own network settings did
Fixed /autocompact warning about high token usage when you choose a smaller auto-compact window
Fixed SessionEnd hooks sometimes not running when you exit while a background command is still running
Fixed claude --help naming a removed tool in its description of --restricted
Fixed claude agents not refreshing any pull request’s status when the data for one of them came back incomplete
Fixed Claude being told a background agent was lost, not resumable, after a cloud session’s container was replaced, when the agent had already been resumed once
Fixed subagents you had typed messages to disappearing from /tasks shortly after finishing, leaving no way back to the conversation
Fixed a completed parent agent dropping off the breadcrumb (its child shown re-rooted at top level) while you were viewing the child
Fixed the agents view taking a typed word such as “up”, “down” or “escape” for that key when input arrived in a burst, which could move the peek mid-reply or clear a draft
Fixed automatic tool search (ENABLE_TOOL_SEARCH=auto) turning off part-way through a conversation, for example while MCP servers reconnect after a resume
Fixed a login refused by forceLoginOrgUUID leaving the refused organization’s token stored, or live after /login
Fixed the diff view in Claude Desktop and Remote Control sessions not noticing a conflicted cherry-pick or revert in reftable repositories
Fixed the Artifact tool’s verbose and ctrl+o line reading Artifact("(unprintable path)") while a call’s input arrives; its row now shows “Waiting…” and “Running…” as Bash’s does
Fixed the first transcript entry written after resuming a session being lost when a crash had cut the transcript’s last line short
Fixed /branch dropping messages, and claude purge skipping subfolder projects, when they contain a Unicode line or paragraph separator (U+2028, U+2029)
Fixed plugin WorktreeCreate and WorktreeRemove hooks not running when Claude Code starts with --worktree (not yet with --tmux)
Fixed OpenTelemetry tool_result events missing git_commit_id after git commit -q in repositories using reftable ref storage
Fixed a prompt that a mod’s prompt.submit hook rewrote or dropped still being recorded as typed in the OpenTelemetry user_prompt event and interaction span, and in session title requests
Fixed a note meant for Claude about mod hot-reloading appearing in the transcript as if you had typed it
Fixed agent hooks ignoring their model: aliases like haiku now resolve, a subagent’s model no longer overrides it, and an unavailable model falls back to the caller’s instead of allowing the action
Fixed --worktree sessions sometimes starting from the wrong commit when a tag or branch was named like a commit ID, and their starting git status naming a branch other than the new worktree’s
Fixed the branch showing as “.invalid” and --worktree failing to reopen a worktree in repositories using git’s reftable ref storage
Fixed Claude naming files in the session scratchpad by a bare filename or relative path instead of their full path
Fixed claude remote-control servers giving up on renewing their connection after a brief sign-in error, such as a locked keychain; they now retry, and warn when you need to run claude /login
Fixed --worktree failing in a worktree of a bare repository when origin’s default branch can’t be fetched; the fallback base is now the current checkout’s HEAD, not the main repository’s
Fixed starting Claude Code in a VS Code, Cursor or Devin Desktop integrated terminal launching the editor’s command-line tool twice to check for the extension; it now launches it once
Fixed a mod’s prompt.edit hook not being raised for a newline entered with the chat:newline keybinding (Ctrl+J, or a rebound Enter)
Fixed a conversation failing on every turn with a 400 error when the API rejected an MCP tool’s input schema; Claude Code now sends that tool without parameters for the rest of the conversation
Fixed resuming a headless or Agent SDK session losing the recent messages a compaction had kept, when the compaction followed a reply cut at the output token limit (compactions from this version on)
Fixed Claude not being told about an MCP server’s tools and instructions until its next tool call, when the server finished connecting after a compaction
Fixed Remote Control sessions being marked stopped while still running, on a computer serving several sessions at once
Fixed resuming a headless or Agent SDK session losing its compaction summary or bringing back pre-compaction history, when the compaction followed a retried or unfinished reply in the same turn
Fixed Claude polling a background command’s output file or sleeping while it runs
Fixed feature flags and staged rollouts staying stale behind a TLS-inspecting proxy whose certificate is trusted only through the OS certificate store
Fixed claude daemon stop --any printing “stopped” while a stuck background service kept running: it now waits, force-kills the service, and says so with exit 1 if it is still there
Fixed claude daemon stop exiting with no output, and leaving sessions listed as running, when telemetry is turned off
Fixed Write, Edit and NotebookEdit in Cowork cloud sessions reporting success for a path on your own computer, where the file never arrived
Fixed Claude searching for deferred tools already loaded earlier in the conversation when a session resumes a history that never listed them
Fixed secondary (dim) text looking the same as normal text under the dark ANSI theme and on 16-color terminals
Fixed cloud sessions hanging 5 minutes per turn when the organization’s policy can’t be read; the turn now ends promptly and says why
Fixed a cloud session sometimes running an already answered message a second time after the session restarted during a long reply
Self-hosted runner: Fixed the runner and orchestrator freezing (no polls, /healthz or SIGTERM shutdown) while nobody reads their output; logs keep the latest 256 KiB and count drops (not on Windows)
[VSCode] Fixed fast mode staying on after usage credits ran out, which made each request be refused and re-sent; it now turns off until you turn it back on, with an error notice
[VSCode] Fixed the Thinking toggle switching to Off on models that always think; the toggle is no longer shown for those models
[VSCode] Fixed “Edit prompt” on a flagged message opening the file or command menu over the restored prompt; Enter now sends it as written
[VSCode] Fixed Shift+dragging a file onto the prompt on Windows inserting an unreadable /c:/… path instead of a mention relative to the working directory
[VSCode] Fixed changes to VS Code’s chat font size settings needing a window reload or being undone by a theme change; diffs and the plan preview now follow them too
[VSCode] Fixed “Resume session” and tabs restored after a reload opening an empty new conversation instead of one that had moved into a git worktree
[VSCode] Fixed ↑ then Enter on a recalled slash command running it without its arguments; the command and file menus no longer open over a recalled prompt until you edit it
[VSCode] Fixed Shift+dragging a file from the Explorer or an editor tab onto the prompt inserting nothing in WSL, SSH and Dev Container windows
[VSCode] Fixed Ctrl+Alt+F toggling Focus view instead of opening Find in the Explorer, other tree views, or the Debug Console on Windows and Linux
[VSCode] Fixed the check for sessions open in other windows or terminals creating extra processes on macOS: it now starts /bin/ps directly instead of searching PATH for ps on every check
[VSCode] Windows: Fixed a conversation showing “still open somewhere else” after a crash or power loss, when Windows had since restarted and given the old process ID to another program
[Cloud sessions] Fixed “Allow for this task” missing from Cowork’s approval prompts for connector tools where an organization turns off “Always allow” (regression in 2.1.292)
[Cloud sessions] Fixed most commands in the / menu losing their descriptions in cloud sessions once you sent a second message
[Remote Control] Fixed the diff view in Remote Control sessions on claude.ai and the desktop app showing deleted and renamed files as modified; requires Claude Code v2.1.296 or later on your machine
[Claude Tag] Fixed Claude in Slack not answering another app that tags it in a thread under a message Claude itself posted to the channel
[Code Review] Fixed Code Review ignoring @claude review comments from people with write access whose GitHub organization membership is private; their comments now start a review
[Code Review] Fixed Code Review’s “paused for this repository” comment sending admins to Code Review settings; it now says who can fix it and links the Git providers page

2.1.299

Tue, 13 Oct 2026 16:00:00 GMT

Added

Added CLAUDE_CODE_DISABLE_FILE_MENTIONS environment variable: Claude gets the paths of @ file mentions to read with its file tools, not the files’ contents
Added idle compaction in the terminal: a 200K+ token conversation left idle for about 54 minutes is compacted before its one-hour prompt cache expires, so your next message doesn’t reprocess it all
Added CLAUDE_CODE_IDLE_COMPACT_MIN_TOKENS to change idle compaction’s 200K-token minimum; "idleCompaction": false in settings.json turns it off. Both need v2.1.290 or later
Added $.prompt.media so a prompt.submit hook of a mod installed by managed settings can read the bytes of an image or document attached to the prompt
Added $.session.identity() for mods installed by managed settings: how the session is signed in, and its organization and email when managed forceLoginOrgUUID lists that organization
Added size, weight, mono and tabular to a mod’s Text and named spacing steps (xs to xl) to its Box; bold is deprecated in favor of weight
Added --shutdown-drain-sec to claude self-hosted-runner orchestrator: on SIGTERM it stops polling and gives the poll in flight and running spawn hooks up to that many seconds to finish
Added the skill’s frontmatter, source, plugin name and file path to what a mod’s skill.prompt hook receives
Added /effort and /fast in agent view to set what new sessions start with; a bare /model, /effort or /fast there now opens a picker
Added a “safe mode” line to the agents view peek panel for background sessions started with --safe-mode
Added a one-time note when plan mode won’t ask before most edits or commands because bypass permissions is available
Added --disallow-tools and a disallowed_tools case field to claude plugin eval to keep specific built-in tools, such as Agent, out of eval runs
Added support for turning off the attribution block in Claude Desktop’s Code tab: set CLAUDE_CODE_ATTRIBUTION_HEADER=0 in the env of a Claude apps gateway’s code policy
Added a field to the attribution block in Claude Code sessions behind a Claude apps gateway; remove the block with CLAUDE_CODE_ATTRIBUTION_HEADER=0
Added a queue door to the session.append mod hook, so a mod can make the transcript’s queue records differ from the prompt as sent
Added a note in /plugin and claude plugin validate naming a mod’s hooks that are skipped where an organization manages Claude Code
Added /usage warnings for max effort, workflows, always-on context and large tool results
[Claude Tag] Added the ability for Claude in Slack to delete a canvas it created in a channel when someone asks it to

Changed

Changed plugin hooks and workflow scripts to refuse values they hand back that nest deeper than 28,000 levels, with an error naming the limit (workflow scripts allowed 100,000)
Changed actions a plugin hook can block to be refused, not let through, when the hook cannot be handed them or cannot hand back its answer; a tool that already ran has its result withheld
Changed requests to claude.ai’s connector proxy and to Anthropic-hosted MCP servers to no longer follow HTTP redirects; redirects by a connector’s own server are unaffected
Changed MCP requests in cloud and self-hosted runner sessions to no longer follow HTTP redirects from the session’s MCP proxy
Changed skill and command loading: one whose file or folder name has hidden, direction-changing or blank-like characters, < or > is no longer offered until renamed; such a name: is ignored
Changed ui.render trees in claude plugin test: each mod’s Box or Text root now carries part: { plugin } naming the mod, so exact-tree assertions must include it
Changed WebFetch page reads to pick their effort as web searches do: the caller’s level on the caller’s own model, otherwise the level settings give the small model
Changed claude plugin test to fail a call to a mod’s served $ method that has not answered within ten seconds, as a session does
Changed MCP allow rules to reach only the server they name: mcp__a no longer allows a server named a__b or a_; write mcp__<server>__* with the server’s whole normalized name
Changed agent tools: lists to take only the named MCP server’s tools; list a server whose name contains __ as mcp__<whole name>__*
Changed Claude in Chrome in Cowork cloud sessions outside auto mode: an approved-site action the safety classifier flags now asks you instead of being refused, unless managed settings apply
Changed cloud session and Remote Control MCP connectors to negotiate MCP protocol version 2026-07-28 by default on installs that fetch no flags; MCP_PROTOCOL_NEGOTIATION=legacy opts out
Changed MCP tool descriptions and server instructions from Anthropic’s first-party MCP servers at api.anthropic.com to reach Claude in full instead of being cut at 4,096 characters
Changed auto mode in Cowork cloud sessions: a PermissionRequest hook can no longer approve shell commands or subagents; those prompts wait or are denied
Changed the resume command printed at exit: it names the session by its ID and no longer by its name, so that nothing in a session name can run when the line is pasted
Changed the resume command printed at exit of a worktree session: it uses -w and -r if the long flags do not fit the terminal. If neither fits a kept worktree, rows above it say where to run it
Changed /btw side questions in non-interactive sessions to return a timeout error when still unanswered after 11 minutes
Changed UserPromptSubmit hooks to run before a skill or custom slash command expands, so a hook that blocks the prompt now also stops its embedded shell commands
Changed a skill’s own front-matter UserPromptSubmit hook to first run on the prompt after the one that invokes the skill
Changed the turn.start mod hook to also hear subagents’ and teammates’ turns, not only the main loop’s; tell them apart by e.agentId (absent on the main loop)
Changed the errors shown when /ultrareview can’t upload a repository to stop suggesting git add ., which could stage or commit untracked files such as .env
Changed the cyber safeguard notice to no longer ask people to apply to the Cyber Verification Program
[Cloud sessions] Changed deleting a self-hosted environment to turn off its routines right away, with the reason shown on each routine, instead of leaving their runs to fail
[Claude Tag] Changed how Claude in Slack corrects a message it got wrong: it edits the message in place and adds a short “Edited” note instead of striking through the old text
[Claude Tag] Changed Claude in Slack to join channels with more than 100 members quietly, with no intro message

Show 16 improvements

Self-hosted runner: Improved what setup and doctor say when the runner’s machine has no git credentials
Improved the error shown when a cloud session is refused because your claude.ai login was rejected or has expired: it now tells you to sign in again with claude auth login
Improved enforcement of managed permission rules, managed hooks and organization MCP tool names against user-installed mods
Improved memory and disk use when PDFs are @-mentioned: their bytes are no longer kept in the session transcript
Improved sandboxed Bash on Linux: Esc and Ctrl-C now work while wildcard read rules are being expanded for a command
Improved the startup warning for an unrecognized model ID: it is now one short line under the welcome banner with a docs link, instead of a long raw message
Improved the plugin-authoring skill’s steps for sharing a mod: Claude asks public or private and checks the files before creating a GitHub repository
Improved the Skill tool’s “Unknown skill” error to suggest a skill’s listed name when Claude wrongly adds the anthropic-skills: prefix to it
Improved /reload-skills to say it re-sends the full skill list to Claude, which is how to get skills back after compaction
Improved the error shown when a worktree cannot be created because its base commit does not resolve: it now says how the lookup ended and the likely reasons, such as a repository without a commit
Improved the error for creating a worktree at a bare-repository layout’s root: it now explains the layout instead of an unrelated git error
Improved artifact watching: a local session can now watch up to 25 published artifacts at once, up from 10
Improved background agent notifications: they now say when an agent is only waiting on its own background work, got a message too late for its result, or was stopped by a usage limit
[VSCode] Improved startup time in workspaces without a Python environment by starting Claude while the Python extension loads
[VSCode] Improved startup: the model picker and slash command menu now fill in right away in a new window on a folder you’ve opened before
[Cloud sessions] Improved the deploy command shown when you create a self-hosted environment or environment key: it shows in full, wraps between arguments, and has a visible copy button

Show 131 bug fixes

Fixed the error for a denied cloud session, which could point to the wrong organization when a key from apiKeyHelper was in use
Fixed sessions on a gateway-specific model name behind a custom ANTHROPIC_BASE_URL ending with “Prompt is too long · automatic compaction failed” near 200K tokens instead of sending the request
Fixed a mod that submits a prompt at the end of every turn keeping a headless run going past --max-turns, --max-budget-usd, an interrupt, or the end of the host’s conversation

Fixed the Write and Edit tools creating a mod in a session’s mods folder without asking in accept-edits mode when the config directory’s path has no .claude in it
Fixed installed mods that kept running in an open session after being turned off remotely; they now unload between turns
Fixed Edit and Retry in Cowork and claude.ai cloud sessions failing on a message stopped while its UserPromptSubmit or mod prompt.submit hooks were still running (regression in 2.1.296)

Fixed memory growing without bound when debug output goes to stderr and the parent process stops reading it
Fixed rm prompts on shell -c scripts that don’t run rm. An rm built at run time in a script Claude Code can’t read no longer prompts unless CLAUDE_CODE_STRICT_INLINE_SHELL_RM_PROMPT=1
Fixed double-clicking a word in an expanded transcript row in fullscreen mode collapsing the row instead of selecting the word
Fixed claude mcp list, claude doctor and /status reporting an empty .mcp.json as invalid

Fixed a Remote Control prompt being lost when another queued prompt in the same batch failed to deliver
Fixed a Remote Control prompt that had passed its hooks being dropped from prompt history when Stop interrupted the next queued prompt’s hook
Fixed sign-in, MCP servers and project trust appearing lost on Linux after a sandboxed command left an empty .config.json in the config directory

Fixed SDK and headless sessions staying in auto mode after the host switched to a model that doesn’t support auto mode
Fixed MCP servers named constructor or prototype in an MCP config never being connected
Fixed tools of an MCP server named constructor or toString asking for permission in auto mode and bypass permissions mode
Fixed a spurious “synced[0] commands path not found” plugin error at startup when another Claude Code process had just updated a claude.ai-synced plugin
Fixed the Artifact tool advising a retry when a publish that requests connectors or other access was refused by the server or a proxy (HTTP 403); it now says so and what to tell the user
Fixed Cowork cloud sessions staying on an old account plugin after a plugin reload that timed out or a restart that reused a recent sync
Fixed document blocks being dropped from your own message sent while Claude is working
Fixed Claude in Chrome asking for permission while no browser is connected; it now says the extension is not connected
Fixed the fullscreen “Update installed” notice being hidden behind the idle “/clear to save tokens” hint; it now shows beside the hint
Fixed a mod hook, with or without a .catch, being run again without end when it waits on another mod’s noun that does its work outside the call
Fixed the Claude apps gateway serving models that a policy’s availableModelsMatch: exact or deniedModels blocks; it now answers 400 and leaves them out of its model lists
Fixed the server-managed settings request to Anthropic carrying a third-party gateway’s API key when a managed settings file sets ANTHROPIC_BASE_URL
Fixed streams through a custom ANTHROPIC_BASE_URL being aborted after 180 seconds with no data arriving; they now wait 300 seconds, whether or not feature flags are loaded
Fixed a mod’s tool.describe or prompt.section answer that changed after $.ui.invalidate never reaching Claude; the new answer is now sent on the next turn
Fixed a settings file being ignored when enabledMcpjsonServers or disabledMcpjsonServers held a single server name (letters, digits, - or _) as a plain string
Fixed claude plugin test pausing a hook’s time budget while a served $ method it had called kept making $ calls after answering
Fixed high memory use after resuming a cloud or Remote Control session that had run many subagents
Fixed plugin hooks being skipped when they pass a very deeply nested tool input or message on with next()
Fixed a value a mod’s hook passes to next(), returns, or sends to a $ method being refused whole when one of its getters throws a RangeError; now only that key is refused
Fixed /usage, the approaching-limit warning (terminal and VS Code) and the status line sometimes showing more than 100% used (anthropics/claude-code#92238)
Fixed wrapped text mixing CJK or emoji with Latin words losing its last line or leaving a blank row at some terminal widths
Fixed a cloud session sometimes ignoring the answer to a permission prompt or a question when the answer was given while the session’s worker was being replaced
Fixed bold, italic and other nested text styles running over table borders or being lost on wrapped rows

Fixed long conversations losing newly attached images on every turn after one oversized image was refused by the API
Fixed the plugin_loaded telemetry event reporting has_hooks as false for plugins whose hooks are a hooks module, built-in plugins included
Fixed images attached while Claude is working (VS Code, desktop app, SDK) being sent at full size, which led to repeated image errors in long conversations
Fixed the image coordinate hint being missing or slightly off for large near-square images on newer models
Fixed feature flag, startup, fast mode, profile and feedback requests to Anthropic carrying the API key configured for a third-party gateway (ANTHROPIC_BASE_URL); Anthropic API keys are still sent
Fixed a mod’s hot reload ignoring a fix saved right after a failed reload; saving a mod file without changing it no longer reloads the mod
Fixed mods loaded from source files being refused when a hook hands $ to a function declaration imported from another file of the mod
Fixed a regression in 2.1.296 where cloud and headless sessions could run an approved tool call twice if a new message arrived as the session resumed after a restart
Fixed scheduled tasks being announced for the wrong minute: the scheduling tools now report each job’s actual next run time
Fixed mods’ hooks being handed values with __proto__ keys silently removed, which could skip a tool.check guard on a tool call another mod made
Fixed claude -p saying nothing when a settings file fails validation: text-output runs now list the file and the invalid entry on stderr
Fixed long pastes in terminals without bracketed paste losing all text after an invisible control character, such as a mis-decoded curly quote
Fixed managed settings and organization policy not being fetched when the stored login’s plan was changed locally on machines whose MDM or managed-settings file sets forceLoginOrgUUID
Fixed MCP connections over HTTP hanging for 30 seconds and failing when a server never ends the body of its reply to a notification (anthropics/claude-code#99014)
Fixed MCP servers added to a running headless or SDK session being connected before some policy checks ran; a blocked server is now reported as failed without being contacted
Fixed claude mcp list, claude mcp get and subagent MCP servers starting a server that a policy check blocks; it is now reported as blocked without being started
Fixed /reload-plugins not loading a plugin installed from another terminal a moment earlier
Fixed blank rows appearing under CJK and emoji text squeezed into a one-cell column, as in a very narrow terminal
Fixed text cut in the middle beside wide characters leaving a cell unused or being cut twice, and an emoji vanishing where a color changed inside it
Fixed bare mode notices in background sessions telling you to restart without --bare, which keeps the mode; they now name /stop and claude --resume, as safe mode ones do
Fixed ← not saying why it stayed put over a queued message while Remote Control is on
Fixed $.http.fetch in mods refusing a 304, 204 or 205 response that declares a Content-Length over the 4 MiB body limit

Fixed Read failing on PDF page ranges in remote sessions on Linux that run without elevated privileges
Fixed Enter answering a question or permission prompt that had been held back while you typed an unsent message

Fixed self-hosted runner sessions shutting down MCP servers added through an --exec-path wrapper’s own --mcp-config when connectors change mid-session

Fixed permission prompts cutting off or wrapping too early when the reason text contains keycap or joined emoji
Fixed forceLoginOrgUUID and forceLoginMethod from MDM or the managed-settings file being hidden or replaced by server-managed settings
Fixed --bare sessions leaving out an MCP server named constructor or prototype that --channels asked for
Fixed resuming a conversation from before /clear reattaching to the Remote Control session of the conversation after it

Fixed the diff view listing a new file whose name begins or ends with a space under the wrong name
Fixed MCP tool calls in headless and SDK sessions sometimes failing or running twice when a background reconnect closed the connection they were running on
Fixed /btw side questions in non-interactive sessions not being cancelled when the session ends, and running a second time when the same request arrived again mid-run
Fixed sandboxed commands on macOS being able to read or write a denied path by its real location when the denied path passes through a symlink
Fixed sandbox denyRead and allowRead globs with braces, parentheses or backslashes in a folder’s name being read differently by Claude Code’s settings checks than by the sandbox

Fixed worktree-isolated sessions accepting some awk programs the isolation guard should refuse
Fixed claude mcp add <name> -- <command> --background being started as a background session
Fixed a prompt or reply of --bg or --background to a background session being taken for the flag, which could start new sessions over and over instead of delivering it
Fixed a custom slash command’s embedded shell line running twice when a newer message interrupted the command while its prompt was being checked
Fixed --worktree sessions leaving a folder behind in .git/worktrees in repositories using git’s reftable ref storage
Fixed claude self-hosted-runner sessions using Anthropic-managed git showing tracked files as staged deletions when starting in a reused clone whose remote is still empty
Fixed Ultracode not being announced to scheduled tasks and other delivered headless turns when ultracode is on in settings
Fixed MCP OAuth sign-in, token refresh and sign-out not sending configured headers/headersHelper values, which broke servers behind an authenticating proxy
Fixed the Artifact tool reporting a spurious one-line difference against the live page, and refusing the publish, when a large page with a line break after <head> is published again unchanged
Fixed $.ui.open reporting a mod’s pane as placed in sessions where no surface draws it, such as Claude Code for VS Code and claude -p
Fixed the agent.spawn mod hook not running when a finished subagent or a killed teammate is resumed: the hook’s event now carries resume, and a mod can refuse it
Fixed claude plugin validate rejecting a mod’s $.state references when plugin.json has no types key and the contract is at ./types/index.d.ts
Fixed a mod’s dimColor text looking the same as plain text under the dark ANSI theme and on 16-color terminals
Fixed plan mode running a write (an MCP tool’s, a file’s, a shell command’s) that a PreToolUse hook or a mod’s tool.check hook allowed
Fixed background subagents in auto mode sometimes sending their final report twice, once as the result and once as a message
Fixed SendMessage not finding a subagent by name after the CLI restarted and resumed the session (names given before the last compaction still need the agent ID)
Fixed replies cut off at the output token limit ending the turn silently, with no retry or error, after a request fell back to non-streaming mode
Fixed Read garbling UTF-16LE files with a byte-order mark, and Write dropping byte-order marks or silently converting Windows-1252, Shift-JIS, GBK or UTF-16BE files to UTF-8 (now refused)
Fixed cloud sessions sometimes leaving a message unanswered when the worker was replaced right after a compaction
Fixed cloud sessions and CLAUDE_CODE_RESUME_INTERRUPTED_TURN sometimes answering a finished turn again after a restart, when a tool ended the turn and a skill loaded in the same step
Fixed photos sent over Remote Control being dropped when their copy could not be saved on your computer; Claude now still sees the photo
Fixed files sent over Remote Control sometimes not arriving in long-running sessions
Fixed files of 30 to 35 MiB sent over Remote Control or to a cloud session not arriving
Fixed a user-installed mod’s $.env.set changing the environment or shell prefix that command hooks from managed settings start with
Windows: Fixed the process-liveness check leaving orphaned PowerShell processes behind on busy machines until memory ran out
Windows: Fixed PreToolUse and PermissionRequest hooks that set no shell failing open when Git for Windows isn’t installed; a guard that fails now blocks the call
Windows: Fixed Bash commands failing with “command not found” for a whole session when Git Bash did not report its PATH at startup
Self-hosted runner: Fixed sessions that wrote output before their first turn being left with no release timer, ignoring --retire-at and delaying shutdown
[VSCode] Fixed an unsent prompt and its attachments being lost when switching to another session and back
[VSCode] Fixed unused blank chats keeping a background Claude process running after starting a new conversation
[VSCode] Fixed the mic button showing an internal error message when you are signed out of claude.ai; it now offers to sign you in
[Cloud sessions] Fixed a memory spike that could crash a session when many of its existing output files were re-sent to it at once
[Cloud sessions] Fixed saving an edited routine silently moving it to a different environment when its own had been deleted or wasn’t in the list; the routine now keeps its environment
[Cloud sessions] Fixed Sessions search in a self-hosted environment’s admin details finding nothing when you paste the session ID from a session’s link
[Cloud sessions] Fixed the Sessions and Runners lists in a self-hosted environment’s admin details saying the list is empty when a search just has no matches
[Remote Control] Fixed Remote Control sessions whose computer can’t be reached still appearing to send your messages; your text now stays in the box and Send is off until it reconnects
[Claude Tag] Fixed Claude in Slack staying silent on untagged posts that a channel’s own instructions tell it to answer, such as posts that tag someone else, in channels with guests
[Claude Tag] Fixed Claude in Slack reporting a reply to another channel’s thread as posted when it isn’t a member there; it now says the reply wasn’t delivered and how to fix that
[Claude Tag] Fixed Claude in Slack sometimes ending a turn without posting its answer when a self-hosted runner’s image has no python3
[Code Review] Fixed Code Review’s monthly spend-limit comment and check-run card sending admins to Claude Code settings; they now link the Usage page, where that limit is set

2.1.296

Thu, 08 Oct 2026 16:00:00 GMT

Added

Added a code key to the Claude apps gateway’s managed.policies[]: the same settings as cli, also applied in Claude Desktop’s Code tab; beside desktop, it turns on Claude Desktop’s gateway mode
Added autoCompactWindow to subagent frontmatter and --agents definitions, so a subagent can auto-compact earlier than the main conversation’s window
Added CLAUDE_CODE_WORKFLOW_SUBAGENT_MODEL to run every workflow agent on one model while other subagents keep theirs
Added CLAUDE_CODE_OVERLOADED_RETRY_MAX_DELAY_MS environment variable to set a longer maximum delay for the backoff when retrying an overloaded (529) request
Added a note in /plugin on a plugin whose hooks are left out because another enabled plugin has the same name
Added an allow_large option to the Read tool so Claude can read a text file past the usual size limits in one call when it needs the whole file and the context has room
[Cloud sessions] Added a status filter to the Sessions and Runners lists on a self-hosted environment’s Activity tab in admin settings; you can pick several statuses at once
[Claude Tag] Added creating, editing and deleting workspace and channel memory files on the Activity page’s Memory tab for members with the Claude Tag Admin permission

Changed

Updated /cost, the status line, --max-budget-usd and the SDK’s cost figures to price Sonnet 5.5 cache reads at $0.10 per million tokens (was $0.20)
Updated the bundled dataviz skill: lighter violet for the seventh series in light mode, softer primary text in dark mode, and compact y-axis labels like 1K
Changed the default limit on MCP tool descriptions sent up front and on MCP server instructions from 2,048 to 4,096 characters
Changed ←: a turn or ! command started while the session moves to the background is now stopped instead of finishing out of sight
[VSCode] Changed Claude in Chrome to ask before browser actions in every session, including one connected with @browser, as the terminal does; allowing a site for the session stops repeat asks
[Claude Tag] Changed Claude in Slack to show the footer with the session link, model and cost only on its newest reply in a thread; the reply before it drops the footer

Show 9 improvements

Improved fullscreen mode: the link under the mouse pointer is now underlined to show it can be opened
Improved transcript toggle (ctrl+o) responsiveness in code-heavy conversations by caching syntax-highlighted code blocks
Improved Claude Desktop’s Code tab behind a Claude apps gateway: when a session can’t start, including on a machine not set up for the gateway’s code settings, the reason shows as a reply
Improved the errors for a refused cloud session: they now say why your organization’s policy couldn’t be loaded, and name an API key or auth token that overrides your claude.ai login
Improved --debug output to name unrecognized frontmatter fields in custom agent files, with a hint for likely typos
Improved auto mode: a tool call that wasn’t run because auto mode’s check had no usable answer now shows as a dim “Not run” row instead of a red error
Improved --debug output for hooks: command hooks on tool calls, prompts, SessionStart and Stop now log their command, plugin, outcome and duration when they finish, so a slow hook is identifiable
Improved CLAUDE_CODE_TRANSCRIPT_LOCAL_GC: a large transcript file is no longer rewritten when that would free under 10% of it
[Code Review] Improved Code Review admin settings to say why a setting couldn’t be saved, such as a policy restriction, instead of a generic failure message

Show 56 bug fixes

Fixed managed-settings PreToolUse hooks that deny a tool call with "continue": false, and managed prompt hooks that block one, refusing the call but not ending the turn
Fixed PostToolUse hooks in managed settings not applying updatedMCPToolOutput in some sessions
Fixed headless sessions starting a folder’s .mcp.json or plugin MCP server that was switched off for that folder, after changing directory or reloading plugins
Fixed a Claude apps gateway that serves allowedProviders with "gateway" locking out laptops that name that gateway in user settings
Fixed a saved Claude apps gateway sign-in being ignored on machines whose managed settings set forceLoginMethod to gateway with no forceLoginGatewayUrl (regression in 2.1.295)
Fixed --teleport opening an empty conversation when the session’s history could not be read
Fixed token counts for Haiku 5.5 and other models that take only adaptive thinking, which failed behind some gateways and were counted with budget thinking elsewhere
Fixed resumed subagents being told that the user rejected a tool call that a session shutdown had interrupted
Fixed hook output being altered when it contained text resembling a plugin hint tag
Fixed secret redaction in shared transcripts and debug logs missing some values that follow a key with no value, including in JSON written inside a shell string
Fixed a stray 52;c;… escape sequence printed on screen after copying in older VTE-based terminals such as MATE Terminal
Fixed toasts and notifications waiting unseen for as long as the /diff panel or dialog was open
Fixed Esc or an interrupt during a UserPromptSubmit hook or a mod’s prompt.submit hook ending headless sessions, clearing the typed prompt, or letting the unchecked prompt through
Fixed SessionStart hooks of a plugin loaded after a headless session starts being skipped when a different plugin with the same name, or another spelling of it, had already run
Fixed claude self-hosted-runner printing misleading errors when registration is refused: it now names the org admin setting, or says a restarted on-demand runner needs a fresh work order
Fixed a self-hosted runner session’s git fetch, pull and push failing while another session of the same repository starts on a runner with --capacity above 1
Fixed workflow scripts silently truncating results, agent options and other values nested deeper than about 20,000 levels, and deeply nested results writing huge task output files
Fixed a plugin’s served $ methods running in the main session’s working directory instead of the calling agent’s, and ignoring the turn their calling hook holds
Fixed $.agent.register succeeding from a mod’s hook that was still running after the mod was reloaded or removed; the call is now refused
Fixed $.http.fetch in mods refusing a HEAD request when the response declares a Content-Length over the 4 MiB body limit
Fixed claude plugin marketplace add, marketplace update and plugin install failing with an internal error for a marketplace named like constructor; add now refuses such names clearly
Fixed a plugin secret named constructor or prototype being deleted by the next save of that plugin’s options
Fixed cloud sessions skipping auto mode’s checks on Claude in Chrome actions that a saved permission allows when their feature flags had not loaded
Fixed CLAUDE_CODE_RESUME_INTERRUPTED_TURN re-running a finished turn after a restart when an MCP tool result had ended that turn
Fixed Bash permission checks auto-approving some commands that assign the BASH_ARGV0 shell variable and then use it; these now prompt for approval
Fixed Edit and NotebookEdit replacing every non-ASCII character in files that are not valid UTF-8 (Windows-1252, Shift-JIS, GBK); such edits are now refused
Fixed a prompt sent just after ← being run twice, once unseen in the foreground, when the background service was slow to answer
Fixed a prompt sent while SessionStart hooks were still running vanishing when ← moved the session to the background; it is still not sent, but ↑ now brings it back
Fixed a late-loading plugin’s SessionStart hook output reaching the new conversation after /clear in headless sessions
Fixed PowerShell commands not seeing variables that hooks write to CLAUDE_ENV_FILE (when the file holds only plain assignments)
Fixed Claude calling cloud sessions non-interactive and suggesting /mcp or claude mcp when an MCP server needs authentication
Fixed /code-review ending on a raw JSON array in cloud sessions, the Agent SDK and IDE integrations; the findings now print as a numbered list
Fixed auto mode occasionally refusing one update to your own artifact, saying its sharing had changed when it had not
Fixed skills synced from claude.ai never finishing their install, and being downloaded again at every sync, when several sessions share a config directory
Fixed a plugin synced from claude.ai being disabled when the marketplace dependency it declares was also synced from claude.ai
Fixed a startup hang on macOS when plugin paths copied from a Linux machine pointed under /home
Fixed the Workflow tool refusing script files with CRLF line endings, such as files checked out on Windows
Fixed OpenTelemetry tool_result events missing git_commit_id after git commit -q or git -C <dir> commit
Fixed CLAUDE_CODE_TRANSCRIPT_LOCAL_GC dropping a message from the saved transcript when its text held a Unicode line or paragraph separator (U+2028, U+2029)
Fixed claude purge leaving a prompt in the history file when its text held a Unicode line or paragraph separator (U+2028, U+2029)
Windows: Fixed PowerShell commands longer than about 1 KB always asking for permission, so allow rules and read-only detection now apply up to 32 KB
Windows: Fixed stdio MCP servers being force-killed at shutdown; stdin now closes first and the process tree is killed only if the server is still running after 300 ms
Windows: Fixed claude plugin install failing for GitHub owner/repo plugin sources on machines with no GitHub SSH key; the clone is now retried over HTTPS
Windows: Fixed rm -rf /c/Users/<name> in Git Bash not asking in bypass permissions mode
[VSCode] Fixed claudeCode.spinnerVerbs missing from the extension’s settings, so settings.json now completes and validates it; a malformed value no longer breaks the chat panel
[VSCode] Fixed chat links written as a full Windows path, such as C:\repo\file.ts or file:///C:/repo/file.ts, not opening the file on Windows
[VSCode] Fixed the working indicator still animating when reduced motion is turned on in your OS, in VS Code, or with the prefersReducedMotion setting
[VSCode] Fixed the prompt cache clock reading warm after the panel caught up on messages late, such as after the display was off or a remote window reconnected
[Cloud sessions] Fixed every cloud session waiting for a self-hosted runner showing the same queue position; each now shows how many sessions are ahead of it
[Cloud sessions] Fixed a message you send while Claude is still replying in a cloud session jumping above that reply when it finishes; it now stays below it, including after a reload
[Claude Tag] Fixed links to URLs that contain parentheses breaking in some of Claude’s Slack replies and task checklists, which showed stray bracket text and opened the wrong page
[Claude Tag] Fixed Claude’s Slack replies drawing color swatches beside codes that only look like hex colors, such as six-digit pull request numbers
[Claude Tag] Fixed the plugin confirmation card Claude posts in a Slack channel showing a plugin’s ID instead of its name
[Claude Tag] Fixed Claude in Slack posting a card to remove a plugin the channel’s own settings don’t include; it now explains where the plugin comes from instead
[Claude Tag] Fixed Claude in Slack sometimes losing its reply when a session in a self-hosted environment moved to a new runner partway through a task
[Code Review] Fixed the Code Review check sometimes staying “in progress” on a pull request after the review finished; it now shows the review’s result

2.1.295

Wed, 07 Oct 2026 16:00:00 GMT

Added

Added onFailure: "block" for command and HTTP hooks: a hook that can’t start, times out, or exits with an unexpected code blocks the action instead of letting it through
Added Program Status Protocol (OSC 7501) support: terminals that implement it can show whether Claude Code is working, waiting on you, or done
Added quoted text to the /copy picker, so a drafted message copies without its > markers
Added a warning to claude plugin install, enable, disable and marketplace add when the settings file they write to does not load
Added a line on stderr, when it is a terminal, that says what a claude -p run is waiting for when it stays open after its last turn
Added support for timeouts.upstream_ttfb_ms on the Claude apps gateway’s Bedrock, Vertex, Foundry and other cloud upstreams: a value you set now limits how long a stream may take to start there, after which it fails over or gets a 502
Added a “Backgrounding cancelled” message when you stop the turn while ← is waiting for the current tool to finish
Added an optional models list to every Claude apps gateway upstream: only the listed models are sent there, on failover too, and one * in an entry is a wildcard
Added support for forceLoginMethod: "gateway" and forceLoginGatewayUrl in your own user settings on machines with no managed settings, so /login opens on that Claude apps gateway
Added advice to claude plugin validate when a plugin’s README has no install line: it prints the line to paste and never changes the exit code, even with --strict
Added upstream_request_id to the Claude apps gateway’s inference audit event: the request ID from Amazon Bedrock, the Anthropic API or another upstream, for support cases
Added $.ui.notify for mods: raises a native notification through your own notification setting and says which channel sent it
Added children to a mod’s Button: strings and Text, so a row of a list is one pressable with a chip or a dim detail inside
Added CLAUDE_CODE_RETRY_WATCHDOG_MAX_WAIT_MS to limit how long unattended retry mode (CLAUDE_CODE_RETRY_WATCHDOG) waits out 429 and 529 errors
Added a request-id header to the Claude apps gateway’s successful inference responses, so request_id in Claude Code telemetry matches the gateway’s audit log
[VSCode] Added a chat row for files Claude sends you: click a file’s name to open it in the editor; Claude’s caption shows underneath, and the row stays visible in Focus view
[Claude Tag] Added a confirmation in Claude Tag admin settings before adding a channel manager moves that member to Custom roles, which can remove their other access

Changed

Changed MCP tool descriptions the model loads through tool search to be cut at 16,384 characters instead of 2,048
Changed subagents to preload at most 32 skills from the skills field, each once; a subagent with the Skill tool can still invoke the rest
Changed Ctrl+C at the idle prompt of an attached background session to leave a pending /loop wakeup alone, so pressing it twice detaches and the loop keeps running; press Esc to stop it
Changed claude agents stopped with its background service (macOS, or Linux without the service installed): running sessions now stop in about a minute unless it is run again, and a notice says so
Changed claude.ai connectors to negotiate MCP protocol version 2026-07-28 by default on installs that fetch no flags; MCP_PROTOCOL_NEGOTIATION=legacy opts out
Changed Artifact pages with no background of their own to show on white instead of off-white
Changed what Claude and you read when a mod denies a tool call after the tool ran: it now says the tool ran and a plugin withheld its result
Changed tab stops to count from where a text starts instead of from the screen’s left edge: an answer indented by 2 has its first stop 8 cells in, where it was 6
Changed the Artifact tool’s permission prompts with telemetry disabled to the same five questions other installs get, instead of asking before each read of someone else’s artifact and each data edit
Changed scheduled and Run now routine runs in installs with telemetry disabled to publish new private artifacts, and update your own, without asking, as in other installs
Changed toasts from your organization’s mods to show ahead of other mods’ toasts instead of waiting behind them
Changed the Claude apps gateway to start with a warning and serve a desktop policy key its bundled Claude Desktop schema doesn’t know, so new Desktop settings need no gateway upgrade
Changed WebSocket (ws) MCP servers: a message over 16 MiB is no longer parsed and closes the connection, the limit the other transports already have
Self-hosted runner: Changed the runner to stop passing CCR_AUTO_MODE_ALLOW, CCR_AUTO_MODE_ENVIRONMENT and CCR_AUTO_MODE_SOFT_DENY into a session’s environment
[Claude Tag] Changed the settings confirmation cards Claude posts in a Slack channel to stay open for 30 minutes instead of 10
[Claude Tag] Changed Claude’s notice that a channel shared across Enterprise Grid workspaces uses organization defaults to post only when someone mentions Claude, at most once a month

Show 13 improvements

Improved token counts behind a Claude apps gateway on Amazon Bedrock, which /context and large file reads use: the gateway now gets them from AWS’s CountTokens API instead of a one-token model request. Grant bedrock:CountTokens to use it
Improved the Claude apps gateway to log a warning every 30 seconds while its PostgreSQL database is read-only, saying what fails and how to recover
Improved the status shown in Remote Control, claude.ai and the desktop app for a session waiting on a permission prompt to name an MCP tool by its server and readable name instead of its mcp__server__tool identifier
Improved background requests behind a Claude apps gateway to use Haiku 4.5 instead of the session’s model, falling back to the session’s model where the gateway does not serve Haiku 4.5
Improved how the Claude apps gateway handles models not listed under models: in Amazon Bedrock regions outside AWS’s US geography. AWS always refused those requests; the gateway now tries the model in your own region, and a refusal names the model to add
Improved headless rate_limit_event usage-limit warnings to say whether the account has extra usage turned on
Improved the built-in plugin-authoring skill: it no longer tells a session with no terminal to run terminal commands, and explains sharing a mod only when asked
Improved Grep input handling: a search sent with grep’s -l, -c or -r flag now runs instead of failing the call
Improved claude plugin validate and plugin loading: when a hooks module is refused over a rebound top-level var, the error now names the line that rebinds it, the cause, and a fix
Improved the Workflow tool’s scriptPath refusal: it now says to pass the script inline via script, the route that works in sessions without a Read tool
Improved what Claude is told when a large file it sends fails to upload with no reason given, so it reports the failure instead of shrinking the file
[Cloud sessions] Improved how quickly a cloud session catches up after its connection drops: activity you missed now appears all at once instead of row by row
[Cloud sessions] Improved the setup script box in the cloud environment form: it starts taller, grows with your script, and can be resized by dragging

Show 97 bug fixes

Fixed every request failing on a [1m] model when a gateway, Bedrock, Vertex or Foundry refuses the context-1m beta; Claude Code now resends without it
Fixed claude -p text output dropping earlier responses when background work started another turn; each turn’s response now prints when the turn ends
Fixed remote MCP servers in headless and SDK sessions staying disconnected after an outage longer than 15 seconds, or reconnecting in a tight loop to a server that drops each connection right after it connects; repeated drops now back off, up to 30s
Fixed remote MCP connections being dropped when a server’s error reply happened to contain a network error name
Fixed MCP servers that repeat a pagination cursor being asked for the same page up to 20 times at every connect
Fixed CSS, JavaScript and XML files returned by MCP tools being saved as .bin, which the Read tool refuses; font and icon files now get their own extension too
Fixed Bash tool calls failing when the model passes command_description instead of description
Fixed Claude in Chrome not applying a site deny rule written with port 80 (host:80) to plain http:// pages on that host
Fixed /plugin’s Errors tab removing a marketplace that failed to load, and uninstalling its plugins, on Enter without asking first
Fixed claude plugin marketplace add reporting success for a marketplace whose name no plugin can be installed under; such an add is now refused
Fixed CLAUDE_AUTO_BACKGROUND_TASKS moving a subagent to the background while an edit or shell command waited behind it, which started that call before the subagent finished
Fixed PushNotification saying a push was not sent in claude remote-control sessions right after a phone message, without the /config toggle, or when started from inside Claude Code
Fixed files sent from remote sessions being refused as “could not be vouched for” when more than 256 were sent at once
Fixed a rare failure to load managed settings at startup right after a login refresh
Fixed /tui exiting without a message, or with a raw system error, when Claude Code could not be started again
Fixed a link address shown as text being hidden by a colour or conceal style a reply left on, including where it wraps in a table or a question preview
Fixed Fable models listed in availableModels not appearing in the /model picker for sessions signed in to a Claude apps gateway; such a model now shows its built-in row in place of a modelPicker row added for the same model
Fixed the Claude apps gateway’s admin spend view showing a developer’s old groups and group cap after their session stopped carrying groups
Fixed CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC hiding the Claude apps gateway spend limit in /usage and the status line. The spend limit request goes to the gateway the session is signed in to
Fixed subagents in their own linked worktree being shown the parent session’s git branch, status and recent commits
Fixed Claude stopping at the end of the current tool when text typed in the prompt cancelled backgrounding with ←; Claude now keeps working in the foreground
Fixed --tools and --restricted not applying to built-in tools that register after launch, and deprecated tool names reaching tools outside the caller’s tool set
Fixed an interrupt not ending the turn until a timeout while Claude waited for an MCP server’s resource list
Fixed a mod’s hook being handed a deeply nested tool input cut short with no error, so a guard could pass content it never saw
Fixed Esc not stopping a self-paced /loop that was moved to the background with ←; cancelling a pending wakeup now shows a notice
Fixed commands and hooks in background sessions inheriting FORCE_COLOR=3, which put color escape codes into the output Claude reads
Fixed claude agents starting a new background service as it exited when both were stopped with a session open (for example at a reboot), which could delay shutdown and restart an interrupted session
Fixed a custom agent named worker being shown as “Agent” in auto-mode denial notices and in the activity lists of task detail views
Fixed Bash permission checks for for-loops over glob patterns, improving permission-check accuracy
Fixed forked skills invoked from Workflow subagents delivering their results to the main conversation instead of the invoking agent
Fixed in-process agent teammates failing their first SendMessage call until they loaded the tool through tool search
Fixed Claude being told on resume that an unfinished background workflow may have been stopped by TaskStop, which can never be the cause
Fixed Claude not being told when you stop a long-running MCP tool call from the tasks panel or a connected client
Fixed a background session’s /loop stopping without notice when its next wakeup came due while the session’s process was down; the session now says so and Claude is told
Fixed raw terminal hyperlink bytes in a reply or a teammate’s message being drawn as a clickable link with a hidden address
Fixed plugin marketplaces whose repository has large git submodules failing to add or refresh: only the submodules that hold plugin files are now fetched
Fixed the /advisor dialog showing a checkmark on a saved advisor model that is no longer available; it now opens on “No advisor”
Fixed the notification for an MCP tool call that moved to the background showing a shortened task id
Fixed vim mode’s ~ moving the cursor past the last character of a line, so x after it did nothing, and 3~ running on into the next line
Fixed the cursor landing one character too far after pasting accented text copied from macOS (such as a file name) into the middle of the prompt
Fixed the terminal freezing, with ctrl+c ignored, when a response ran to tens of thousands of lines
Fixed calls a mod makes while it reloads during a plugin hooks worker restart getting past another mod’s guard hook that has a .catch; such calls are now refused
Fixed plugins whose hooks module nests code thousands of levels deep failing to load or validate with a bare stack-overflow message
Fixed claude plugin test passing a session.append hook that removes tool call, tool result or thinking blocks that a real session keeps
Fixed Claude not being told it can resume background subagents with SendMessage after a session was killed and resumed a second time
Fixed a file being treated as already read after a Bash command such as cat ran without printing it
Fixed plugin options named constructor or prototype always reading as their default and never reloading the plugin when edited
Fixed a mod’s hot reload missing a save made while /reload-plugins or session start was reading the mod’s files
Fixed the mod hot-reloading question being asked again every turn for the whole session when it is approved without picking an answer
Fixed /model, /fast and /output-style saving their setting without asking a plugin’s config.set hook
Fixed bold text being drawn faint in piped output when it directly follows dim text
Fixed replies whose quotes nest deeper every few lines freezing the terminal for seconds and using gigabytes of memory
Fixed a mod’s hot reload missing a save made within a few milliseconds of its last reload, which left the mod on its old version until the next save
Fixed claude mcp serve background Bash results not naming the output file, and its tool description promising a notification that never arrives
Fixed an async SessionStart hook’s unchanged context being added to the conversation again on every resume
Fixed variables a SessionStart hook writes to CLAUDE_ENV_FILE not reaching the Bash tool after an in-app /resume or /branch
Fixed a skill’s allowed-tools and effort being dropped when the Skill tool finished before the response stream ended, which denied the skill’s Bash commands in -p runs
Fixed a tampered cache of server-managed settings making a person’s own plugin count as organization-managed on machines whose managed settings list or enable plugins
Fixed Claude 3 Opus and Claude 3.x Sonnet sessions being offered tool search, which those models reject, where feature flags are unavailable
Fixed generated type files being written into a --plugin-dir plugin’s folder in -p and SDK sessions; they are now written only where a mod is being developed
Fixed text with tabs or bidirectional control characters losing its end at the edge of the screen or drawing over nearby rows
Fixed /model saying a Max effort pick was saved as your default for new sessions; Max applies to the current session only
Fixed an async hook’s JSON output being ignored when it is printed over several lines
Fixed the Read tool rejecting calls with an empty pages parameter instead of treating it as omitted
Fixed project-scope plugins not loading in VS Code on Windows due to drive-letter casing (anthropics/claude-code#74612)
Fixed plugin install and uninstall at project or local scope on Windows missing the install record, or adding a second one, when only the drive letter’s case differs
Fixed a queued message being lost when pulled back into the prompt with ↑ or Esc just after ←: prompt history now keeps it
Fixed mod hot-reloading turning off for the whole session when an SDK host closed its enable question before anyone answered; the question is now asked up to three times
Fixed a prompt that a mod’s prompt.submit hook rewrote or dropped still being saved as typed to prompt history and to the transcript’s queued-prompt records
Fixed non-interactive sessions telling you about MCP servers that need authentication when your request doesn’t use them
Fixed the claude_code.auth OpenTelemetry login event not being emitted on Claude apps gateway sign-in. The event is exported when OpenTelemetry is configured on the machine or the session is already signed in to the gateway
Fixed a plugin that adds very large interfaces getting another plugin unloaded when the plugin hooks worker stalls
Fixed Edit treating a file as fully read when its contents changed without its modification time advancing
Fixed short command output with Windows line endings (CRLF) being drawn on a single line
Fixed a stopped scheduled task coming back on resume after a rewind, and a scheduled task being lost on resume after Esc or a rewind following a compaction

Fixed cloud sessions hanging when a mod’s session.receive hook asked for permission before passing a message on
Fixed macOS background sessions that restart together after an update sometimes running outside the stable app wrapper, so folder-access prompts could reappear
Fixed an MCP sign-in or reconnect that finishes late in headless and SDK sessions relisting a server set with setMcpServers() as your own
Fixed changing the auto-update channel in /config saving before a plugin’s config.set hook was asked
macOS: Fixed a file count at session start that could reach other apps’ data and raise the “access data from other apps” prompt when a session starts in the home folder or above it
[VSCode] Fixed “Fork conversation from here” and Rewind’s conversation restore failing with “Message not found in session” after a background agent’s activity or one of the panel’s own status lines
[VSCode] Fixed Ctrl+Shift+Tab, Cmd+Shift+Tab and Alt+Shift+Tab in the chat input also switching the permission mode, and Ctrl+Tab accepting the suggested prompt
[VSCode] Fixed keyboard focus bouncing between two Claude views visible at once, which could send typed text to the wrong conversation
Self-hosted runner: Fixed git fetches being cut off while the git server was still reporting progress on a large repository; CLAUDE_RUNNER_FETCH_SERVER_PROGRESS_CAP_MS tunes or turns off the wait
[Cloud sessions] Fixed a message sent right after unarchiving a cloud session sometimes getting no reply because no container could start for it
[Cloud sessions] Fixed some older routines starting their runs without ever giving Claude their saved prompt; those routines now run their prompt again
[Claude Tag] Fixed channel links and @-mentions in a forked thread’s “Continued from” card showing as raw Slack codes
[Claude Tag] Fixed Slack’s Working status spinning on under a thread after @Claude !restart had already confirmed the restart
[Claude Tag] Fixed another app’s or bot’s @Claude going unanswered in a busy channel where Claude had stopped reading untagged messages

[Code Review] Fixed Code Review still skipping a large CLAUDE.md’s rules when the pull request edits that file
Fixed web searches and agent hook evaluations taking much longer at xhigh and max effort

2.1.294

Wed, 07 Oct 2026 16:00:00 GMT

Fixed prompt and agent hooks written as instructions (such as “Block commands that…”) allowing what they should block
Improved how prompt hooks on Stop and SubagentStop written as instructions (such as “Carry on if the build is broken”) are judged, so Claude is less likely to stop early

2.1.293

Tue, 06 Oct 2026 16:00:00 GMT

Added

Added Claude Haiku 5.5 (claude-haiku-5-5), now the default Haiku model on the Anthropic API — 1M context, $0.10/$0.50 per Mtok ($0.50/$2.50 for prompts over 100K)
Added agentType to the subagentStatusLine payload, so scripts can tell custom subagent types apart
Added isDeferred to $.tool.register for mods: false lists the tool’s schema in the prompt from the start instead of behind tool search

Changed

Reverted the auto mode denial message change from 2.1.281 that told Claude a denial covers the outcome, not only the exact command
Reverted the 2.1.290 fix for cloud sessions staying asleep after a container restart lost a pending /loop wakeup or scheduled task; Claude is no longer told, and the session stays asleep
Changed claude.ai skill syncing to check for changes about every 40 minutes, instead of every 10, while no session is in use
Changed the order of agent lists and of MCP servers announced to the model: names with non-ASCII characters now sort after ASCII names
Changed OpenTelemetry claude_code.at_mention logging to emit at most 100 agent and 100 MCP-resource events each time a prompt is read
Self-hosted runner: Changed the orchestrator to sleep 4 to 6 seconds between polls instead of a constant 5, so several replicas for one environment stop polling at the same moment
[Claude Tag] Changed Claude in Slack to join announcement channels, where only admins can post, without posting its intro
[Claude Tag] Changed the limit on channel rules in Claude Tag admin settings from 20 to 50 for each workspace and for the organization-wide Slack page

Improved Claude in Chrome: fewer page actions are refused when the browser is slow to report its tabs
Improved the Claude in Chrome message in cloud sessions when the browser can’t be reached: if you belong to more than one organization, it now says the extension must be signed in to the same one, and how to change that
Improved the Bash edit diff note to say the listed files changed while the command ran, which can include writes by other processes
Improved artifacts: Claude pins libraries to exact versions two weeks old or older

Fixed Claude sometimes treating its own last actions before a context compaction as done after it, and retracting or redoing finished work
Fixed a memory leak where an HTTP MCP connection kept every request it had sent until it closed
Fixed a message sent while Claude was working being lost when ← moved the session to the background; if a queued message can’t move, ← now stays put and says so
Fixed /model effort ←/→ wrapping past the highest or lowest level, which could accidentally save Low as a model’s default effort
Fixed /tui disconnecting Claude in Chrome in a session started with --chrome, and ignoring --no-chrome
Fixed Claude being told to continue or message subagents with SendMessage in sessions, including resumed ones, where a host, a permission rule or a --tools list removed that tool
Fixed subagents and --agent sessions being told a built-in tool was disabled for the whole session when only their own tool list left it out
Fixed a claude.ai-synced skill’s edited description sometimes not reaching the model until a new conversation or /clear
Fixed claude logs, stop, kill, rm and claude daemon status, stop, uninstall sometimes signing you out when your login had expired or was about to
Fixed the footer’s agents count disappearing after a momentary failure to read the sessions folder (for example, too many open files)
Fixed a custom agent named worker being shown as “Agent” when it starts, and the agent detail dialog’s title losing the agent type once the agent finishes
Fixed the Artifact tool’s transcript row briefly reading Artifact("(unprintable path)") while a publish call was still streaming in
Fixed the /ultrareview upload on Linux wrongly refusing some repositories, such as one inside another checkout, over a settings file that “could not be parsed” while a sandboxed command was running
Fixed the /ultrareview upload’s refusal over split-index files advising a git command that could leave git unable to read its index

Fixed Remote Control uploading a session’s starting history again after every credential recovery
Fixed PushNotification reporting “Remote Control inactive” in sessions started with claude remote-control
Fixed a mod’s hooks on classic.* events being skipped while the plugin hooks worker restarts, which left settings hooks to answer without them
Fixed claude plugin test failing for mods that call $.session.append; tests can read the appended rows back with the new mock.session
Fixed claude plugin eval refusing every Bash-granting run on Macs with Docker Desktop (links under ~/.docker/bin); the refusal now names which part of a credential store held the link
Fixed the Claude apps gateway refusing to start when a desktop policy sets Claude Desktop’s built-in browser keys, such as builtinBrowserEnabled
Fixed claude agents offering bypass permissions that background sessions then ignored when consent was saved only in .claude/settings.local.json or a --settings file; it now asks for consent first, and a session that ignores bypass shows a short notice that stays
Fixed ← backgrounding a session after 10 seconds while the prompt held unsent text (it now cancels the move) or a question was waiting for your answer
Fixed Esc, or No without feedback, on a permission prompt not stopping the turn when ← had just been pressed to move the session to the background
Fixed the agents view briefly replacing the session list with placeholder rows when the sessions folder could not be read (for example, too many open files)
Fixed path-scoped rules and nested CLAUDE.md files not loading when Claude views a file with a single-file cat, head, tail, sed -n or grep command in the Bash tool instead of the Read tool
Fixed pasted text that begins and ends with the same words sometimes being sent to Claude as if it had been typed
Fixed a skill name in pasted text being treated as typed when an accent typed or pasted right after the paste merged into its last letter
Fixed /feedback returning to the drafts list after Ctrl+O or Ctrl+Z while a report was sending, leaving the send impossible to cancel
Fixed claude purge stopping silently (exit 0, or a hang in a terminal) when a file or folder could not be deleted; it now deletes the rest, lists what it could not delete, and exits 1
Fixed keybindings.json checks: a lone ” ” (space key) is no longer reported as an error, and keys like “ctrl+ k” now get a warning
Fixed vim mode >> and << on a line of only spaces leaving the cursor past the end of the line, where a following x deleted nothing
Fixed vim mode: after deleting whole lines in Visual mode (V then d) the cursor lands on the first non-blank, and . after it acts on the cursor’s line
Windows: Fixed stopping a status line, hook, or shell command sometimes terminating an unrelated process that had been given the same process ID
[Claude Tag] Fixed Claude in Slack saying a workspace isn’t set up in Enterprise Grid channels shared across workspaces when Slack labels a message with a workspace that isn’t connected
[Claude Tag] Fixed Claude in Slack stopping mid-task in a channel when an admin changed the channel’s connectors, plugins, skills or rules; the change now applies once Claude finishes

[Claude Tag] Fixed an access bundle’s Add a connector dialog in Claude Tag admin settings showing every Google connector as connected after one Google sign-in

2.1.292

Mon, 05 Oct 2026 16:00:00 GMT

Added

Added --marketplace <source> to claude plugin install: adds the marketplace if needed, under the same policy checks as claude plugin marketplace add, then installs the plugin from it
Added an effort parameter to the Agent tool, so Claude runs a sub-agent at the effort level you ask for
Added CLAUDE_CODE_OVERLOADED_RETRY_BASE_DELAY_MS environment variable to set a longer base delay for the backoff when retrying an overloaded (529) request
Added prompt.autocomplete, an event a mod hooks to add its own rows to the prompt box’s autocomplete list
Added prompt caching to $.model.complete for mods: prompt and system take blocks of text, and cache: true on a block caches the request up to it
Added workflow agents to the agent.spawn mod hook, with their run and index, so a mod can refuse them
[Claude Tag] Added an Edit button to the Allowed domains card on a channel’s Configure page, so Enterprise admins can open the access bundle that sets the channel’s domains
[Code Review] Added the period’s total with its change from the previous period, and a breakdown by repository, to the PRs reviewed chart in Code Review analytics

Changed

Changed local (stdio) MCP server connections to negotiate protocol version 2026-07-28 by default on every install, including Bedrock, Vertex and Foundry; MCP_PROTOCOL_NEGOTIATION=legacy opts out
Changed claude plugin test: a failed expect inside a hook the test registered, or a stub answer the engine refuses, now fails the test instead of passing silently
Changed usage limit messages to write claude.ai settings links with https:// so terminals and apps can make them clickable
Changed scheduled and Run now routine runs to publish a new artifact only you can see without asking for approval; artifacts that request connectors or other access still ask
Changed agent names to allow at most 256 characters: a longer one is rejected, and a skill’s or a plugin file’s name longer than that is ignored
[Claude Tag] Changed the first message of a Slack thread continued with !fork to a card showing where it came from, the request, and who asked, with a link to the original thread
[Claude Tag] Changed the organization-wide and default spend limit boxes on Claude Tag’s spend limits page in admin settings to save only when you press Save or Enter, not when you click away

Show 13 improvements

Improved startup of claude -p and SDK sessions: the first turn no longer waits for HTTP and SSE MCP servers to answer resources/list
Improved rendering speed of long bulleted or numbered replies: they stream, resize and re-open in the transcript (ctrl+o) much faster
Improved Ctrl+C draft recovery: a cleared prompt now stays reachable with Up after a slash command or a sent message
Improved hook output handling: <system-reminder> tags written in a hook’s output are escaped before they reach Claude
Improved tool input handling: Grep accepts file_path for path, and Write, WebFetch and Read ignore a few stray parameters instead of failing the call
Improved the steps shown when a marketplace declared in a settings file has a name that looks like an official Anthropic marketplace
Improved sandbox auto-allow: with strict sandbox mode set in user, managed or —settings settings, an interpreter command with an env var prefix like FOO=bar python3 app.py runs unprompted
Improved the Artifact tool’s listing: Claude now sees how many published artifacts you have and can list up to 200 at once instead of 50
Improved cloud sessions after a restart: Claude is now told which stopped background agents it can resume by id
Improved the Claude in Chrome message in claude.ai cloud sessions when the browser can’t be reached: Claude is now told it may continue with alternatives if the user prefers
Improved the /focus tip: it now invites you to try focus view mid-turn and shows how to switch back
Improved startup with local (stdio) MCP servers that ignore the newer protocol check: after one slow connect they are remembered for 7 days and connected the older way without the wait
[Claude Tag] Improved @Claude !status in a channel to say when Claude has stopped reading its untagged messages, why, and that an @-mention starts it reading again

Show 64 bug fixes

Fixed subagent definitions with permissionMode: auto entering auto mode when auto mode is unavailable (disabled by settings, circuit breaker, or a model that doesn’t support it)
Fixed sandboxed commands being able to read the staged file copies of /ultrareview uploads under ~/.claude/seed-admin
Fixed a managed sandbox read-deny path (and user ones beside it) that appears or re-points mid-session not dropping project grants inside it or ending credential injection from files it covers

Fixed a tampered on-disk cache of server-managed settings being able to switch off or unseat the built-in policy plugin while the settings fetch failed

Security: Fixed PreToolUse hook approvals and auto mode bypassing the permission prompt for file reads from network (UNC) paths
Fixed a skill’s or slash command’s allowed-tools rule coming back in a later turn when you leave auto mode or plan mode partway through that turn
Fixed NO_PROXY being ignored for Claude Code’s own API requests (sign-in, policy, feedback, artifacts) when HTTPS_PROXY is set

Fixed claude plugin commands such as marketplace add and install running before an organization’s managed settings had loaded on a first run
Fixed one-shot claude -p and Agent SDK runs stopping a background command 5 seconds after the final result, and one-shot claude -p runs dropping a scheduled wakeup; both are now waited for
Fixed plan mode not being restored when resuming a session from the claude --resume session picker or with /resume
Fixed saved scheduled tasks created after /resume, /branch or /clear never firing, and saved tasks ignoring later creates and deletes after two writes to the tasks file milliseconds apart
Fixed a background session’s /loop silently stopping when the session’s process restarted (for example after a crash), because its pending wakeup was lost
Fixed Grep and Glob reporting no matches when the file or folder they were given could not be read; Claude now retries once or tells you
Fixed the Read tool returning only the first entry, with no error, when a PDF’s pages was a list such as “6,9,15”; it now returns an error saying to read each page or range separately

Fixed /bug, /share and /feedback <text> starting over after Ctrl+O or Ctrl+Z while a report was being sent, and closing as cancelled after it had been sent

Fixed some pasted text reaching Claude as typed text when several pastes overlapped in one prompt
Fixed vim mode leaving the cursor past the end of a line, j/k losing their column on shorter lines, and f/t/F/T/;/, jumping to, or deleting up to, a match on another line of the prompt
Fixed /add-dir path box letting Shift+Enter or a paste add a line break, and treating fast-typed “tab”, “up” or “down” as those keys
Fixed fast typing, input-method text and decomposed accents being dropped while a prompt footer row was selected, and ! leaving the row selected
Fixed fullscreen mode sending a full-screen clear on every window resize and Ctrl+L when iTerm2 is detected, which may be what filled iTerm2’s scrollback with stale pages
Fixed a spurious “could not be examined” note for @-words that name no file when a Read deny rule is set and the working directory is under a symlink

Fixed a compaction summary that repeated /name letting Claude invoke a skill that is reserved for the user
Fixed Write, Edit, NotebookEdit and LSP rows, and single Read, Grep and Glob rows, hiding why a mod denied the call: the row now shows the reason
Fixed a cloud session showing a turn that never ended when its worker was stopped just as the turn finished

Fixed Cowork cloud sessions saying a proxy blocked artifacts when Anthropic couldn’t confirm the organization’s settings
Fixed plugins whose hooks module makes many $.state calls through one const taking minutes to load or validate
Fixed claude plugin validate listing a matcher or state value for a hooks module that the engine reads from elsewhere
Fixed claude plugin validate listing a $.state value read through a top-level var that was declared again or reassigned; such a module is now refused

Fixed plugin interface calls made while the plugin hooks worker restarts running without the hooks other plugins put on them
Fixed a mod’s config.set, state.set, env.set or agent.spawn hook that denies after calling next(e) being answered as a refusal: the hook is now reported as failed, by name

Fixed a plugin’s tool.check hook answering allow running a tool that requires your answer (a question, a plan approval) without showing its dialog
Fixed a mod’s start-up prompt, command or subagent being queued a second time when the hooks worker was replaced
Fixed a mod’s hook that called next(e) and then failed while the turn was interrupted letting the call through; the call is now rejected
Fixed a plugin’s prompt drop or setting deny being ignored when its reason was longer than 4,096 characters

Fixed tool calls made while the plugin hooks worker restarts being answered without the plugins’ permission hooks
Fixed plugin tool.call hooks seeing some tool calls before misnamed parameters were repaired; a hook now sees the arguments the tool will run with

[Cloud sessions] Fixed routine runs occasionally staying listed as running for hours after they had finished
[Cloud sessions] Fixed editing or duplicating a routine turning off its push notifications when the routine had no saved notification setting
[Cloud sessions] Fixed SVG, HEIC, TIFF and other less common image files failing to attach; they now attach as regular files

2.1.291

Mon, 05 Oct 2026 16:00:00 GMT

Fixed a regression in 2.1.290 where cloud sessions could drop answers to permission prompts
Fixed a regression in 2.1.288 where the last messages of a session could be lost when quitting

2.1.290

Sun, 04 Oct 2026 16:00:00 GMT

Added

Added serverToolUses to the result of a mod’s turn.step hook: the tool calls the API ran itself (the advisor), each with its id, name, input, start and end
Added agentId to the tool.check event of plugin hooks, so a hook can tell a subagent’s permission check from the main session’s
Added ceiling to the question and verdict a mod’s tool.check hook reads, naming the approval an organization requires for a tool
Added ThemeKey and Color types to the plugin hooks typings, so an editor lists the theme colors a mod’s drawing can name
Added to claude plugin validate: each hook a mod registers at a gating site is listed with whether it has a .catch (gatingHooks under --json)
Added a Deny button to the Claude apps gateway’s sign-in approval page: it ends the pending sign-in, so the waiting terminal stops within seconds
Added claude attach <name> and claude logs <name>: part of a session name works in place of the id
Added /claude-api managed-agents-onboard <url> to set up the Managed Agents pattern a page describes as ant apply files
Added /claude-api managed-agents-onboard <quickstart-name> to build a Console quickstart template, such as deep-researcher, with the ant CLI
Added a warning when a managed settings file is a link to a file outside the managed settings folder
Added a /status and doctor warning when managed settings ignore user-configured sandbox allowRead paths or allowed domains
[VSCode] Added a screen reader announcement, “Message queued.”, when you send a message while Claude is working
[VSCode] Added a way to review and run a plugin marketplace’s install or update command from the Manage plugins dialog
[Claude Tag] Added fast mode in Slack: mention Claude with !fast to switch a thread to fast mode, moving it to Opus if needed, and !fast off to switch back; replies show (fast) while it’s on
[Claude Tag] Added the optional Path prefixes field when creating a custom connection in an access bundle, so its allow rule can cover only those paths instead of the whole host

Changed

Changed CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC to also skip the startup connection warm-up
Changed Claude in Chrome so that a project’s settings files can no longer turn it on; use --chrome, /chrome or your user settings
Changed the Bash tool to ask for permission before running pyright, which is no longer treated as a read-only command
Changed what a mod’s $.process.spawn rejects with when another mod denies it after the child ran: it now says the call ran and a plugin withheld its result
Changed the background daemon’s log to write a multi-line message as one JSON-quoted line
Changed skills and custom commands to refuse a ! shell command that contains raw control characters other than tab and newline, with a message that shows where they are
Changed /artifacts: opening an artifact in your browser now closes the list
Changed Bash permission checks so that more forms of the ps command ask for approval instead of running without asking
Changed plugin hooks so long text is clipped and logged instead of being refused or dropped silently
Changed background sessions whose scheduled task is gone: they now move to Completed about 20 seconds later and can be updated or shut down when idle
Changed the “Press ← again” confirm on a just-cleared prompt: a second ← no longer has to wait a second before it switches, and holding ← down now switches too
Changed the errors shown when the /ultrareview upload fails at a git step: they name the step and what to try, and no longer repeat git’s own error text
Changed /code-review at medium effort to also report cleanup and CLAUDE.md conventions findings on models without tuned review settings, including Opus 5.5 and Sonnet 5.5
Changed an in-process teammate’s agent_id in Agent results to its agent ID (its name@team address stays in teammate_id); TeammateIdle hooks no longer fire from its subagents or forks
Changed background sessions waiting on a scheduled wakeup (/loop): they are now left running through updates and low memory, where being restarted or shut down could silently lose the wakeup
Changed /model, /effort and /rename sent from claude agents to a busy background session to apply right away, without a confirmation, instead of when the turn ends
Changed the Claude apps gateway’s minimum supported PostgreSQL version from 14 to 11
Changed the interactive session’s WebSearch budget to refill over time (100 calls/hour; CLAUDE_CODE_WEB_SEARCH_REFILLS_PER_HOUR sets the rate, 0 turns it off) instead of ending after 200 calls
Changed CLAUDE_CODE_DISABLE_ATTACHMENTS so a repository’s .claude/settings.json or .claude/settings.local.json can no longer set it; shell, user and managed settings still can
Changed claude plugin update on a plugin loaded from a directory to print just its reason, without the “Failed to update plugin” prefix, as for built-in plugins
Changed the built-in gh api in cloud sessions: a host other than github.com set in GH_HOST or GH_REPO is now refused (use --hostname or a full URL), and stderr notes requests to other hosts
Changed the claude-api skill’s Managed Agents examples to turn off the web tools unless the agent needs them and to use the auto permission policy
Self-hosted runners: Changed claude --environment <id> to create its session through the current Sessions API; printed and JSON session ids keep their session_… form
[VSCode] Changed message timestamps to show by default (turn them off with the Claude Code: Show Message Timestamps setting)
[Claude Tag] Changed the channel instructions limit to 8,192 characters instead of bytes, so non-English text gets the same room, and added a character count beside Save on the Configure page

Improved the Bash changed-files view: when a chained command includes git merge, pull or checkout, it lists the files without full diffs
Improved the Claude apps gateway’s log when an upstream’s cloud credentials or connection fail: the warning now ends with the underlying cause
Improved the error shown when a cloud session is started without a claude.ai sign-in: it now names claude auth login and /login and no longer blames API-key authentication

Improved the error shown when a git config file stops the /ultrareview upload: it is about half as long and says what kind of file is the problem
Improved the errors shown when the /ultrareview upload refuses a checkout: each known cause now has its own message, with a way to fix it
Improved the Claude apps gateway to log a warning during the last 30 days before the certificate it presents to the identity provider expires
Improved Claude in Chrome: a browser_batch call now gets 90 seconds, up from 60, before it is reported as timed out
Improved the Claude apps gateway’s browser sign-in pages: brand fonts, centered layout, and dark mode
Improved responsiveness while resuming large sessions: timers, input and rendering keep running while the transcript loads
Improved the / and @ suggestion lists: the selected row now starts with a ❯ pointer, so you can see it without color
[VSCode] Improved Continue After Reload: tabs reopened after VS Code restarts its extensions now also finish a step the restart interrupted
[VSCode] Improved file pills in messages: hovering one now shows the file’s path from the project folder, so same-named files can be told apart
[Claude Tag] Improved Claude’s notice in your direct messages when your own Claude plan’s usage limit is reached: it shows within seconds and says when the limit resets
[Claude Tag] Improved the earlier Claude in Slack app’s reply when it can’t start a session: it now says what failed and who can fix it, in full only once per thread

[Claude Tag] Fixed a workspace guest’s Confirm on a Claude settings card in Slack removing its buttons for everyone; only the guest sees the refusal, and members can still confirm or cancel
[Claude Tag] Fixed scheduled routines in Slack channels running on a model other than the channel’s default; each run that starts a new session now uses the current default model

2.1.289

Fri, 02 Oct 2026 16:00:00 GMT

Added

Added agent.spawn for teammates, one agent id across plugin hook events, and idle and waiting states in $.agent.list()

Changed

[VSCode] Reverted a 2.1.288 change to claude auth status that may have made sign-outs more frequent

Improved

Improved how quickly large files open in a plugin code pane by laying the highlighted view out once at its final width
Improved the line a mod’s author sees when its band or pane fails to draw: it names the mod and says nothing was drawn

Show 23 bug fixes

Fixed a deny or ask rule on a nested part of a compound shell command not holding over a user-installed mod’s approval on managed machines
Fixed the terminal freezing on short code blocks with many unclosed <script> tags or deeply nested ${ substitutions
Fixed Read deny rules not applying to files @-mentioned, changed, or selected in the IDE through a symlink
Fixed plugin list, plugin eval and plugin update showing a stale copy of a plugin installed from a local folder marketplace, and hot reload for a symlinked --plugin-dir
Fixed installed mods not loading in the first session after an upgrade
Fixed a plugin’s rows above the prompt showing a stale row while the Background tasks dialog was open in fullscreen
Fixed plugin panes drawing nothing when a link used a localhost address, an @ in its path, an uppercase host or a file: path
Fixed a user-installed plugin being able to rewrite the descriptions of an organization-managed MCP server’s sign-in tools
Fixed a freeze or forced quit at launch when a plugin drew a Box with a border style the terminal does not know
Fixed supervised and background sessions ending when a plugin’s on-screen handler threw asynchronously
Fixed sessions ending with an interface error when a plugin region with no height kept growing
Fixed Bash deny and ask rules missing a command behind an environment variable prefix with an expanded value (e.g. TZ="$HOME" rm -rf build) when the sandbox auto-allows commands
Fixed a Bash deny or ask rule being skipped under sandbox auto-allow when a bare variable assignment came before the command
Fixed claude plugin validate skipping the plugin when the folder also holds a marketplace manifest
Fixed sessions ending with “unrecoverable interface error” when a value a mod’s ui.render hook wrote made a row throw while drawn; the engine now draws its own row instead
Fixed text with a tab, a stray escape and a C1 control, or a short text with a tab and CRLF line endings, drawing over the rows below it
Fixed right-aligned content in a mod’s pane or band drawing under the close mark or [-], which now also keep one column in from the terminal’s edge
Fixed a mod’s Client that fails while drawn taking down everything the mod drew around it; it now fails alone and raises ui.fault
Fixed claude plugin validate failing an Anthropic marketplace’s own plugin and listing a clean plugin.json in --json
Fixed a mod’s band that fails to draw briefly telling the cards under it to step aside
Fixed a failed plugin component showing Error or nothing as its reason when the failure carried no message

2.1.288

Thu, 01 Oct 2026 16:00:00 GMT

Added

Added $.ui.selection() for mods: returns the text you last selected in fullscreen mode and, when the selection lies within one transcript row, that row
Added a built-in gh api to cloud sessions whose image has no GitHub CLI, and fixed the built-in sending control characters from file names, jq filters or GitHub errors to the terminal
Added recovery for a prompt cleared with Ctrl+C: pressing Up on the empty prompt brings the draft back, including pasted text and images
Added a re-authenticate prompt when an MCP server asks for more OAuth scope during a tool call
Added --max-findings <n>|all to /code-review to report more or fewer findings than the usual limit; the choice is reused until you pass --max-findings default
Added Ctrl+F to find a session by name and Alt+↑/↓ to jump between groups in the agents view; both, and rename, can be rebound in keybindings.json
Added a screen reader mode announcement of the new permission mode when you approve a plan, including with Shift+Tab

Changed

Changed the background command time limit to apply only in unattended sessions (-p, Agent SDK, CI, cloud); terminal, desktop app and VS Code sessions have no limit
Changed the client-side auto mode classifier to ignore an ANTHROPIC_DEFAULT_SONNET_MODEL pin that names Claude Sonnet 5.5 or Opus 5.5 and use Claude Sonnet 5 instead
Changed claude project purge to claude purge; the old name still works and prints a notice
Changed the agents view n: filter (and Ctrl+F search) so Enter opens the session whose name matches best instead of the top row
Changed /autocompact to save the auto-compact window per model, so each model keeps its own setting when you switch
Changed MCP URL prompts from servers that can’t report when you’re done to wait for “I’m done, continue” before the tool call continues, so you can finish in the browser first

Show 12 improvements

Improved auto mode: when a conversation grows too long for the client-side safety classifier to review, it is now compacted instead of prompting for, or failing, every tool call
Improved screen reader mode: short announcements, such as a deleted word, now stay on screen until your next key press or until something above them on screen changes
Improved screen reader mode: answered questions in question dialogs now say “answered” beside their box
Improved the /usage-credits message shown to Team and Enterprise members whose organization has turned off usage credit requests
Improved cloud sessions: a new conversation’s first turn no longer waits for a stdio MCP server whose config sets alwaysLoad: false
Improved “You should know” notes to say “we”, “the main agent” or “you” depending on who was responsible for a decision
Improved the error for an artifact database write refused at the database’s size limit: it now states the limit and what frees space
Improved Bash permission prompts to give a shorter reason when part of a command can’t be checked before it runs
Self-hosted runner: Improved the built-in gh api: a refused gh command now prints its gh api equivalent, --paginate follows every page of a repository’s lists, and a nested claude no longer removes it
Improved Remote Control’s recovery from an expired server credential: sessions stay connected during renewal and are kept if it gives up after a server outage
[Claude Tag] Improved Claude to also follow a related Slack thread in another channel that it only read, so updates there reach the conversation that depends on them
[Claude Tag] Improved save errors on a channel’s Configure page: too-long channel instructions now say to shorten them, and a save refused for lost access no longer says to try again

Show 64 bug fixes

Fixed mid-response API timeouts failing the turn: non-interactive sessions and subagents now continue from the partial response, and thinking-only responses are retried
Fixed long conversations failing with “Prompt is too long” instead of auto-compacting when the last reply reported zero token usage
Fixed --resume sometimes dropping files and other context that a compaction had just restored
Fixed a resumed session sometimes not saving the last response of a turn, so that the next --resume showed the prompt unanswered
Fixed resume occasionally loading a transcript cut short when the same session rewrote the file during the load
Fixed resuming a conversation started on 2.1.286 or earlier dropping the model’s earlier thinking

Fixed plugins loaded with --plugin-dir not showing “Configure options” in /plugin
Fixed background sessions ending when a plugin was reloaded or disabled while one of its timers or reads was still running
Fixed sandboxed heredocs with an unquoted delimiter (python3 <<EOF) asking for approval on every run under sandbox auto-allow when the body holds only plain text and simple $VAR references
Fixed Bash tool permission check to prompt before a BASHPID assignment whose value the shell would evaluate as arithmetic, instead of allowing it silently
Fixed fullscreen sessions exiting with “unrecoverable interface error” when opening the background tasks dialog while a plugin or mod showed rows above the prompt
Fixed Claude reporting a message to another session as delivered when that session held it: the notice now says it wasn’t delivered and names the session, and in SDK sessions Claude can now learn of it mid-turn
Fixed OpenTelemetry claude_code.tool.blocked_on_user spans reporting unknown source or decision in -p and SDK sessions and for PreToolUse hook approvals
Fixed permission asks that ended unanswered, in -p or on an interrupted turn, emitting no tool_decision event
Fixed Edit and Retry in Cowork cloud sessions refusing a message sent before /compact even though its history was still saved
Fixed unattended sessions (CLAUDE_CODE_RETRY_WATCHDOG) retrying for hours after a very long response stream failed; Claude Code now streams again, and gives up after three timeouts
Fixed /login reporting “Login successful” when credentials could not be saved to secure storage; it now shows the failure, and offers a retry when the new login didn’t take effect (anthropics/claude-code#73861)
Fixed a Stop during Bedrock credential lookup sometimes moving the session to a fallback model instead of ending the request
Fixed a second gcpAuthRefresh/awsAuthRefresh browser sign-in opening when a laptop wakes from sleep while another Claude Code process is signing in
Fixed agent teams: a plugin-defined agent spawned by name now runs with its own prompt, tools, disallowedTools and effort instead of the defaults
Fixed headless (-p / SDK) sessions occasionally ignoring SIGTERM when a supervisor such as timeout or systemd sends SIGCONT alongside it
Fixed restarted cloud sessions restoring a model that the organization’s enforced model list refuses
Fixed MCP tool calls sometimes running twice when a remote server’s result was over 16 MB or could not be parsed
Fixed subagents in Claude Desktop’s Code tab getting none of the tools of a user-configured MCP server named memory
Fixed Claude in Chrome asking before every screenshot and page read on a site you allowed when auto mode is unavailable (such as with disableAutoMode or an older model); typing, navigation and JavaScript still ask
Fixed claude plugin install failing for GitHub-source plugins on macOS and Linux machines with no GitHub SSH key: the clone now falls back to HTTPS and prints a notice
Fixed sandbox.credentials.files entries on git config files not taking effect while permissions.blockReadsOutsideWorkingDirectories is on
Fixed Claude leaving out your organization’s design systems when starting slides or a design with the Artifact tool on Team and Enterprise plans or machines with managed settings
Fixed the keyboard not working on Windows after Claude Code restarts itself (first sign-in to a Claude apps gateway, provider setup, /tui)
Fixed a stall when launching an agent whose tools: lists very many Agent(...) entries
Fixed sessions on Claude 3 Opus and Claude 3 Sonnet failing on every turn after a whole PDF entered the conversation
Fixed the npm auto-updater reporting success when the platform-native binary failed to download and only the placeholder claude stub was installed
Fixed Remote Control cleanup archiving a session that is still connected or was just re-attached by another Claude Code process
Fixed owner/repo plugin marketplaces showing only the second attempt’s error when both the SSH and HTTPS fetch fail; both errors are now shown, with the transport tried first on top
Fixed path-scoped .claude/rules and nested CLAUDE.md files not loading when Write or Edit creates or changes a file in their scope (previously only Read loaded them)
Fixed a dangerous rm (such as one on / or the home directory) inside a bash -c or sh -c script running without a prompt in bypassPermissions mode or under a shell allow rule (anthropics/claude-code#96300)
Fixed LSP tool calls hanging indefinitely when a language server uses dynamic capability registration or stops responding; requests now time out after 60s (per-server requestTimeout)
Fixed idle_prompt notification hooks firing while background agents are still running (anthropics/claude-code#93672)
Fixed PreToolUse and PermissionRequest hooks being skipped when matching them failed or the tool’s input could not be serialized to JSON; the call is now blocked
Fixed the first request in a fresh environment or after a model switch using the built-in output limit and auto-compact window, not the server’s; that request may now wait up to 1.5 seconds
Fixed the “What should Claude do instead?” hint showing on the Interrupted row after sending queued messages with ctrl+enter
Fixed /login in a --bare session running a sign-in the session never reads, which could replace your saved login; it now says which credentials work
Fixed the InstructionsLoaded hook omitting agent_id and agent_type when a subagent’s file access loads a rule or nested CLAUDE.md; rules and nested CLAUDE.md files loaded on file access now also report effort
Fixed the Agent tool in claude mcp serve always reporting no available agents and rejecting every subagent_type
Fixed the terminal cursor not following the typed text in the fullscreen transcript viewer’s search and in /theme’s custom color search
Fixed /permissions in screen reader mode: typing a rule’s number now picks it instead of opening the search box
[VSCode] Fixed a claude.ai connector staying on “Needs authentication” after you authorize it: the MCP servers dialog now offers Check connection
[VSCode] Fixed the opt-in New Conversation shortcut (Cmd/Ctrl+N) starting a conversation in every visible Claude view instead of only the one you are in
[VSCode] Fixed the chat view resuming the next saved session after you archive the one it shows; it now starts a new conversation instead

[Claude Tag] Fixed Claude Tag admin settings offering a “Remove this scope” option, which always failed, on channels whose settings were created automatically
Fixed claude plugin test reporting mods as turned off remotely when it had only read an out-of-date saved setting

2.1.287

Wed, 30 Sep 2026 16:00:00 GMT

Added

Added Claude Mods: plugins may now modify deeper behavior
Added You should know, a built-in mod where a side agent watches your back and flags things you or Claude might miss. Turn it on with /plugin enable cc-plugin-you-should-know@builtin (for first-party sessions with telemetry on)
Added an n:<text> filter to the agents view that matches session names and tasks; a filter now shows matches in collapsed sections and Enter opens the first match
Added prompt_text to the OpenTelemetry user_prompt event, a copy of prompt for backends that nest dotted keys; drop or mask it wherever you drop or mask prompt (anthropics/claude-code#70763)
Added URL prompts from MCP servers on the 2025-11-25 protocol, for example to sign in. If a server no longer connects after this update, add “bareElicitationCapability”: true to its MCP config entry
Windows: Added a startup warning when denying the Bash tool also turns off the PowerShell tool, so Claude has no shell tool
Self-hosted runner: Added a built-in gh api (REST only) for sessions that use Anthropic-managed git on macOS and Linux machines where the GitHub CLI is not installed
[VSCode] Added “Run in background” to a running command or sub-agent, to move it to the background and keep working
[VSCode] Added the output of background shells and Monitors to their cards in the agent map

Changed

Changed a shell write through a repo-committed symlink onto a sensitive file or out of the working tree to name where it lands and wait for a person, on lines with a ~ target too
Changed Opus 4.7+ and Fable to use a 1M context window by default on Bedrock, Vertex, Foundry and the Claude apps gateway, with no [1m] suffix (CLAUDE_CODE_DISABLE_1M_CONTEXT=1 keeps 200K)
Changed replies from claude agents to arrive as queued messages; slash commands other than /stop sent while a turn is running now run when it ends
Changed whole-tool Bash allow rules and allowing hooks to prompt for, not run, shell writes to files Claude Code’s file tools refuse outright (the Anthropic profile store, the host credentials file)
Changed right-click paste on Windows and Linux, and middle-click paste on Linux, to happen when the button is released; moving the pointer away before releasing cancels it
Changed MCP server alwaysLoad: false to defer all of that server’s tools behind tool search
Changed screen reader mode to write new or changed lines without first pausing with the cursor at the start of the line; set CLAUDE_AX_PREPARK_MS=50 to restore the pause
Changed automatic model switches after a flagged message to keep your current effort level instead of the new model’s default
Changed waiting permission prompts to show oldest first, so a new prompt no longer covers the one you’re reading (prompts with a countdown still open on top)
[VSCode] Changed the Claude in Chrome “Enabled by default” switch to also connect the editor’s own sessions, which still ask before browser actions

Show 20 improvements

Improved /config: settings that cycle show ‹ › and step both ways with ←/→, narrow terminals stack each value under its label, and PgUp/PgDn page the list
Improved plugin marketplace errors to say in plain words why a marketplace was ignored or refused, and what to do
Improved plugin listings to note when a plugin’s dependencies were not installed, and updating a plugin now retries an install that did not finish
Improved the Claude apps gateway’s error when Amazon Bedrock rejects a model ID: developers now see which model is unavailable, and the gateway log names the ID that was sent
Improved SDK sessions so a message sent with priority “now” no longer cancels a running web fetch or web search; it keeps loading in the background
Improved /memory: the left and right arrow keys now flip its on/off settings, such as Auto-memory
Improved /skill names typed mid-message: Claude is now told they are skills, including disable-model-invocation ones
Improved the contrast of the prompt input border in light themes and of the ❯ before your earlier messages
Improved delivery of files Claude sends from cloud sessions and Remote Control: an upload that fails on a timeout, a network error or a 502, 503 or 504 is now retried once
Improved what Claude says when a file cannot be sent for a reason that may be temporary: it now mentions that you can ask for the file again in a few minutes
Improved the prompt for a held message from another session to show the message between dashed lines, matching other permission prompts
Improved MCP and other tool permission prompts to show the tool call between dashed lines, matching file edit prompts
Improved MCP startup in headless mode: a remote server whose first connect fails transiently is now retried without waiting for the slowest server to finish connecting
Improved files Claude sends from a remote session: large files now stream from disk instead of being read into memory, and a file over the size limit is refused with the server’s limit named
Improved the explanation Claude gives when the server refuses a file it sends from a Remote Control or cloud session, such as an oversized image
Improved handling of large MCP tool results: less memory, smaller session files, and no extra upload to count tokens for results far over the limit
Windows: Improved Bash tool speed by removing a subshell that ran before every command
[VSCode] Improved the Manage plugins dialog: a failed marketplace add, remove or refresh now says what went wrong
[Claude Tag] Improved Claude’s task list in long Slack threads: background work no longer reposts it as a new message on its own, so people following the thread aren’t notified
[Code Review] Improved the failed-review card on a pull request whose conversation is locked: it now says the lock blocked the review and that nothing was posted or charged

Show 67 bug fixes

Fixed fast mode staying off in remote sessions owned by an agent with no user account, even when the organization allows it
Fixed Remote Control not receiving messages for minutes at a time when a reconnect request got no response; it now gives up after 30 seconds and retries

Fixed switching between Opus 5.5 and Sonnet 5.5 (/model, opusplan) rewriting earlier MCP tool announcements, which could drop earlier extended thinking
Fixed Amazon Bedrock Guardrails blocks that arrive mid-response ending the turn with an API error instead of the guardrail’s message when the reply began with thinking

Fixed a folder’s CLAUDE.md being attached a second time after resuming a session or after a compaction
Fixed background sessions that could not be reopened from claude agents after the agent exited and removed the worktree the session was started in
Fixed /advisor pairing checks: Sonnet 5.5 can now advise Opus 4.7 and 4.8, and advisors the API would refuse are flagged up front instead of being silently dropped
Fixed Bash permission prompts showing internal parser names such as “Contains simple_expansion” instead of a plain explanation
Fixed a cause of fullscreen sessions on slow or busy machines exiting with “Claude Code exited after an unrecoverable interface error” while a scroll key was held in a long conversation
Fixed organization per-tool permission ceilings being silently dropped for an MCP tool named __proto__
Fixed Claude being told to page large MCP results saved as JSON with Read’s offset and limit, which cannot split one long line

Fixed screen reader mode refusing Enter with nothing typed on /rewind’s summarize options, whose added context is optional
Fixed screen reader mode showing a “Tab to amend” hint on approval prompts, where Tab does nothing
Fixed screen reader mode listing arrow keys that do nothing in /permissions and /mcp, and saying “Select with numbers” in empty menus or while a search box has the keys
Fixed screen reader mode leaving out the changed lines in file edit approval prompts and other diffs
Fixed screen reader mode sending the claude --teleport progress screen, and an MCP form field while it is being checked, to the screen reader again on every spinner frame
Fixed CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS not removing the structured-output format from session-title and prompt-hook requests, which Bedrock-backed gateways reject
Fixed screen reader mode leaving out the top lines of a second approval prompt, a changed /config row or the rejected-plan line when the previous screen was taller than the terminal window
Fixed --include-partial-messages sending a cut-short reply’s message_stop late or never, so apps could show the reply as still in progress
Fixed claude agents sometimes not showing the permission prompt a background session is waiting on
Fixed /ultrareview giving advice about .git/info/attributes when the upload stops on a committed .gitattributes it cannot read, such as one saved as UTF-16
Fixed claude remote-control failing to register behind an HTTP proxy with a misleading “Check your organization permissions” error (anthropics/claude-code#97352)
Fixed sandboxed Bash commands on Linux inheriting an open handle on the Claude Code executable
Fixed the running-tool dot and three spinners still moving with the “Reduce motion” setting on, and /rewind’s confirm screen updating its “ago” time while you type a note
Fixed times in claude agents changing every second in screen reader mode; they now change at most every 10 seconds
Fixed a revoked claude.ai login showing a generic API Error: 401 instead of “OAuth token revoked”; in -p mode the error now starts with “Failed to authenticate”
Fixed /ultrareview upload refusals advising you to copy a variable named by a repository’s settings file into your own user settings
Fixed --output-format stream-json and the SDK not streaming the turns of a context: fork skill run by typing /<skill> as the prompt, as they do for the Skill tool’s fork
Fixed /feedback and /bug: the pre-filled GitHub issue no longer includes your recent error messages, and the confirmation screen now lists them as part of the report
Fixed claude plugin marketplace add --sparse and git-subdir plugin installs failing with “transport ‘http’ not allowed” when the repository is served over plain http
Fixed cloud sessions sometimes losing the earlier conversation when the session restarted while it was being compacted
Fixed a plugin reload that overlapped the startup --plugin-url download corrupting the session’s cached copy of the plugin archive
Fixed /desktop quoting partial output when opening Claude Desktop timed out or printed too much output; the error now names the cause
Fixed an MCP connector tool call occasionally running twice, or the connector’s calls failing until restart, when its server changed which MCP protocol version it supports
Fixed SessionStart hooks from synced plugins not running in new cloud sessions
Fixed the transcript’s “N hooks ran” summary and the verbose debug log’s matched-hooks count including Claude Code’s internal callbacks, so one configured hook no longer shows as two
Fixed files Claude sends from cloud and Remote Control sessions failing when the upload finished just after the 30-second timeout; it now waits 35 seconds
Fixed repositories added mid-session in cloud and SDK sessions not loading their skills and plugins, and loading CLAUDE.md late, after Claude changed directory
Fixed PNG, JPEG and WebP images over 8,000 pixels on a side failing to send from a remote session; Claude now sends a scaled-down copy
Fixed messages sent from the Claude apps with 17 to 20 attached files delivering only the first 16
Fixed headless sessions reporting an MCP server as needing authentication after one refused call, even though later calls succeed
macOS: Fixed Remote Control sessions started with claude remote-control stopping mid-turn when the Mac went to idle sleep
Windows: Fixed interactive claude hanging or crashing with “Raw mode is not supported” when its input is piped or redirected; it now says why and exits (use -p for piped input)
Bedrock, Vertex, Mantle: Fixed model availability checks under CLAUDE_CODE_SKIP_*_AUTH sending a different Authorization header than real requests when ANTHROPIC_CUSTOM_HEADERS repeats it
[VSCode] Fixed settings dialogs blaming a timeout when Claude Code’s reply was too large to confirm a save
[VSCode] Fixed reopening a cloud session that the side bar already brought to this machine opening it again in a new tab; the side bar is shown instead
[VSCode] Fixed the side bar’s Web tab not listing cloud sessions started after the window loaded; a failed load now says “Remote server is not connected” instead of “No web sessions yet”
[VSCode] Fixed a tab restored after a reload starting a second Claude process on a conversation the side bar already has open; it now shows the “still open somewhere else” notice
[VSCode] Fixed tool-row file links, session-list links and two hints showing in plain text
[VSCode] Fixed a background agent’s still-running command showing as failed once the main turn ended
[VSCode] Fixed a user’s own /usage or /context command opening the extension’s dialog instead of running when picked from the command menu
[VSCode] Fixed file links in the plan preview tab doing nothing when clicked; they now open the file like links in chat replies
[VSCode] Fixed opening a tool’s input or output in an editor tab failing with “Timeout waiting after 1000ms” on remote hosts such as WSL when the tab is slow to appear
[Cloud sessions] Fixed occasional failures to fetch from or push to GitHub when GitHub briefly refused a newly issued access token
[Claude Tag] Fixed Claude posting a failure warning, such as a spend limit notice, in a Slack thread when a background event like GitHub activity woke it and nobody was waiting on a reply
[Claude Tag] Fixed Claude Tag’s spend limits page in admin settings leaving out recently created and private channels in organizations with many channels
[Code Review] Fixed finding comments and their “Why this was flagged” text stopping mid-sentence; they now end on a complete sentence
[Code Review] Fixed Code Review skipping a pull request after a new push when its review had failed twice on the previous commit; it now reviews the latest commit

2.1.286

Tue, 29 Sep 2026 16:00:00 GMT

Added

Added a count such as “2 of 5” to the permission prompt when several permission requests stack up
Added mouse support for the “N more” rows of lists in fullscreen mode: click one to jump to that end of the list, with hover and pressed states
[VSCode] Added bookmarks: save Claude’s responses and keep them in view in a Bookmarks side panel
[VSCode] Added the questions Claude asks and your answers to the conversation: after you answer a question card, a Questions row shows each question with your picks
[VSCode] Added option previews to question cards in the chat panel: the highlighted choice’s mockup or snippet shows beside or under the options
[VSCode] Added rows under a message that open to the terminal output, browser tab, browser instructions and selected code sent with it
[Claude Tag] Added an Add channel button to Claude Tag’s spend limits page in admin settings, so a limit can be set on any channel, including a private one, from its channel ID or Slack link

Changed

Changed prompts sent while nothing is running or queued to show in the normal text color right away instead of gray
Changed how failed API requests are retried: one limit now covers a whole model call, so with the default retry settings a failing call sends at most 14 requests
Changed --bare to connect only the MCP servers named on the command line, send the model no system reminders, and start no background tasks; under --bare, a shell command that reaches its timeout now stops instead of moving to the background
Changed the send-now key (ctrl+enter) to move a skill’s own shell command to the background instead of ending it
Changed the WebFetch error for a rate-limited domain safety check to tell Claude not to retry it in a loop
Changed plugin installs to refuse npm sources that are git repositories or folders, and to install plugin dependencies only from registry packages
Changed list screens (/artifacts, /mcp, /skills, /hooks and others) to always line up each row’s details in one column after the names
Changed the overflow rows of lists to read ”↑ N more” / ”↓ N more” instead of “N more above” / “N more below”
Changed /hooks to open on one list of your configured hooks grouped by event, so viewing a hook takes one Enter instead of three
Changed the theme picker to a scrolling list that fits your terminal instead of pushing the preview off screen; number keys no longer pick a theme
Changed /exit’s Remove worktree to run after Claude Code stops the servers and shells it started there, which on Windows could keep the folder from being deleted
Changed the claude-api skill’s Managed Agents examples to create environments with limited networking
Removed the browser link from /ultrareview and claude ultrareview output
[VSCode] Changed Stop and Escape to end only the current turn; background agents keep running and can be stopped one by one from the agent map
[VSCode] Changed the ”✻ Claude Code” status bar item to show in every window, so you can open Claude when no file is open
[Cloud sessions] Changed a routine’s page to read “Due” with the scheduled time, instead of a next run time in the past, when a scheduled run is late and hasn’t started

Show 16 improvements

Improved commit guidance: when your project or user skills include one named verify, Claude is now told to run it right before committing, except for docs-only and tests-only commits
Improved send now (ctrl+enter) in a subagent’s view: it now moves the subagent’s running command to the background so your message is read right away
Improved replies from background agents to your messages so they no longer open with a separate recap of what you said
Improved claude.ai artifact link reads: WebFetch now asks the same questions as the Artifact tool’s read (no artifact prompt while the session’s network access is on, one per artifact while it is off), and an auto-mode yes no longer counts where only you can answer
Improved fetch, skill, file read, sandbox network, Claude in Chrome, workflow script and notebook edit permission prompts to match the look of file edit prompts
Improved Bash, PowerShell and Monitor permission prompts to show the command between dashed lines, matching file edit prompts
Improved list scrollbars in fullscreen mode: in most lists the bar no longer shifts as the “N more” rows come and go, and it now has ↑/↓ arrows you can click or hold to scroll
Improved the external editor (Ctrl+G): editors that take a line number now open on the line your cursor is on in the prompt
Improved slash command suggestion responsiveness while typing when many skills or plugin commands are installed; command descriptions now match by word prefix
Improved the output style picker: it now opens on your current style instead of Default, with each style’s description on the line under its name; number keys no longer pick a style
Improved /hooks: the closing line of a hook’s detail screen now says “this hook” instead of “it”
Improved the model fallback notice and the autocompact-thrashing error to say when a fallback dropped the context window from 1M to 200K tokens
Improved responsiveness of SDK and -p sessions when a host re-sends an MCP server enable for a server that is already connected
Improved the protocol page a Claude apps gateway serves at /protocol: it now says not to reject unknown input and matches what Claude Code sends today
[VSCode] Improved the Manage plugins dialog: it says when a turned-off plugin is still on because of other settings, and explains a plugin folder clash
[Claude Tag] Improved the titles of sessions started from Slack as shown on claude.ai: they now read as the words you typed, without Slack user IDs or escape codes

Show 49 bug fixes

Fixed several Claude Code processes and IDE extensions each opening a login browser when gcpAuthRefresh or awsAuthRefresh credentials expire
Fixed claude --resume and --continue sometimes losing every turn after a batch of parallel tool calls when the earlier session crashed or was killed
Fixed API 400 errors after a tool or hook returned an object, number or boolean instead of text, including in resumed sessions
Fixed cloud sessions with very large histories never waking up because the container was stopped while the transcript was still loading
Fixed the Claude apps gateway’s spend meter pricing 1-hour prompt cache writes at the cheaper 5-minute rate, and counting only the first model call’s input tokens on streamed turns that run a server-side tool such as web search
Fixed macOS sessions still showing “Not logged in” or “Login expired” after /login succeeds in another Claude Code window when a leftover ~/.claude/.credentials.json exists
Fixed every turn failing when the Anthropic API refuses the model your default or a model alias resolves to: Claude Code now retries once on the previous model of the same tier
Fixed Remote Control sessions (including claude remote-control) staying connected after your organization’s policy turns Remote Control off; they now disconnect with a notice
Fixed refusal and --fallback-model retries failing when the fallback model can’t run fast; they now run at standard speed, with a one-time notice in interactive sessions
Fixed headless sessions repeating the “MCP servers require authentication” reminder after a successful re-authentication when the MCP discovery cache is enabled
Fixed claude auth status reporting a Console sign-in’s stored API key as claude.ai; it now reports api_key, and the VS Code extension treats that session as an API key session
Fixed /status listing an Anthropic profile beside an API key as if both were in effect; the profile is now marked as not in use
Fixed Claude not being told when a file attached to a message sent over Remote Control did not arrive, and a file sometimes getting only 10 seconds for its last download try
Fixed a Remote Control message that arrived while Claude Code was exiting being marked delivered and then never answered; it now stays queued for the session’s next run
Fixed MCP error messages showing a credential’s value when “Bearer” or “Basic” came before its key name
Fixed percent-encoded Bearer tokens being only partly masked in error messages
Fixed redacted logs and transcripts showing a secret whose key name has an invisible character inside, such as a zero-width space
Fixed logs and transcripts showing part of a URL password that contains punctuation such as ), quotes, ], & or a second @, or that runs past a / to a bracketed host such as [::1] in an ssh URL
Fixed the session transcript in the zip that /feedback saves to disk containing invalid JSON lines after secret redaction
Fixed MCP connectors listing no tools for up to a day after their server dropped the older MCP handshake
Fixed a repeat MCP sign-in request from Claude replacing the pending sign-in link, which could stop that link from working
Fixed /usage not crediting an MCP server for a tool call made while that server was still connecting or had only just connected, such as right after a restart
Fixed plugins enabled on claude.ai occasionally going missing from Claude Code for a session after a transient server error
Fixed a message typed into a running subagent showing twice in its transcript after the subagent read it
Fixed subagent hand-back messages showing a raw task id instead of the agent’s name when the subagent had no registered name
Fixed foreground subagents sometimes missing the task-tracking tools (TaskCreate/Get/Update/List, TodoWrite) in sessions that have them enabled
Fixed subagents spawned with worktree isolation loading the project CLAUDE.md and its imports a second time from the worktree copy on their first file read
Fixed Workflow tool subagents being restarted from their original prompt when a connection stalled for a few minutes mid-response
Fixed /compact, /clear, and /rewind typed while viewing a background agent’s or teammate’s transcript silently acting on the main conversation: a dialog now names the target and asks first
Fixed background jobs showing done while waiting for your approval
Fixed the commit attribution reminder being re-sent inside tool output when a model fallback lasts only one turn
Fixed a click on the space between words of a collapsed row (such as “Thought for 4s”) highlighting the row without expanding it in fullscreen mode
Fixed a row with no details, such as an action row with a long name, pushing every other row’s details to the right in list screens
Fixed files with very long names not reaching a cloud session when attached to it
Fixed plugin errors for a marketplace Claude Code refuses to load: they now say why and how to fix it instead of “not found”
Fixed /plugin’s Discover tab showing a marketplace name unquoted in its “Checking … for new plugins” line when its rows already show that name in quotes
Windows: Fixed claude --bg and the agents view refusing a folder that claude already trusts when its trust record was saved with different letter case
[VSCode] Fixed a second copy of a conversation opening in a tab when it was already open in the side bar; the side bar now switches to it
[VSCode] Fixed settings dialogs reporting a failed save, without re-checking, when Claude Code printed more than 1 MB of output
[VSCode] Fixed an endless “Teleporting session…” spinner when the extension stops responding
[Cloud sessions] Fixed an answered question card or approved tool call getting no reply when the session had gone idle after Claude sent a message
[Cloud sessions] Fixed clearing an organization environment’s setup script in admin settings leaving new cloud sessions still running the old script
[Cloud sessions] Fixed the Runner actions menu on the self-hosted environments admin page closing on its own a few seconds after it opened
[Cloud sessions] Fixed routine runs whose cloud session never started showing as Succeeded in the Runs pane, the routine’s page and the sidebar; they now show as Failed
[Cloud sessions] Fixed clicking an audio or video file in a cloud session’s Outputs card opening an empty file search instead of playing the file
[Claude Tag] Fixed memory recall finding nothing in organizations that cannot use the default Sonnet model
[Claude Tag] Fixed a Slack channel losing its Claude settings when an Enterprise Grid admin moves it to another workspace and the first post afterward doesn’t mention Claude
[Claude Tag] Fixed Claude in a Slack thread occasionally starting over on a fresh machine, losing work it hadn’t pushed, when your reply answered a question it had just asked
[Claude Tag] Fixed public channel names on Claude Tag’s spend limits page in admin settings showing as raw Slack IDs in larger organizations

2.1.285

Mon, 28 Sep 2026 16:00:00 GMT

Added

Added CLAUDE_CODE_DISABLE_WEB_FETCH environment variable to turn off the WebFetch tool
Added claude --desktop to open the Claude desktop app on the current directory, or on a session with --continue / --resume <id>
Added claude plugin configure <plugin> to show a plugin’s options and which are unset, or save new values read from stdin with --values-stdin
Added <server>.<key>=<value> to claude plugin install --config, so a bundled .mcpb MCP server’s own settings can be set at install time and it starts without visiting /plugin → Configure
Added allowedProviders managed setting to limit which API providers a machine may use (Anthropic API, a custom endpoint, Bedrock, Mantle, Vertex AI, Foundry, Claude Platform on AWS, or a Cloud gateway)
Added CLAUDE_CODE_NONSTREAMING_TIMEOUT_RETRIES environment variable to cap re-sends of a non-streaming fallback request that timed out
[VSCode] Added a note under a restored tab’s last message when a window reload interrupted it and no reply will follow
[VSCode] Added a plugin options form to Manage plugins: installing a plugin that has options asks for the unset ones, and a gear on its row changes them later
[VSCode] Added an on-demand diagnostics tool so Claude in the panel can read the Problems panel’s current errors and warnings at any time, not only right after it edits a file
[Claude Tag] Added direct messages with Claude for members on an Enterprise plan Standard or Usage-Based Chat seat who also have Cowork; a seat that includes Claude Code is no longer required

Changed

Changed MCP tools so a tool that sets its own _meta['anthropic/alwaysLoad'] to false stays deferred when its --mcp-config, Agent SDK or plugin server is set to alwaysLoad
Changed background Bash and PowerShell commands to stop after a time limit (their timeout with run_in_background, default 30 min, max 2 h); Claude is notified when one is stopped
Changed Code Review’s pull request reviews and /ultrareview to run when disableWorkflows is on, unless the machine running the review has it set by its own administrator (MDM or the managed-settings file)
Changed sessions behind a custom ANTHROPIC_BASE_URL to use the 1M context window of models that have one (Opus 4.7+, Sonnet 5+, Fable); run /autocompact 200k if your gateway stops at 200K
Changed Team and Enterprise sessions, and sessions whose sign-in plan Claude Code can’t determine, to withhold WebFetch until the organization policy loads if it couldn’t be loaded at startup
Changed /memory so that Auto-memory can no longer be turned on from a background session or from a session one of Claude Code’s own tools started; turning it off there still works
Changed the one-time offer to make auto mode your default permission mode to also show on third-party providers and with telemetry off, when your user settings default to another mode
Changed claude -p and Python Agent SDK sessions on third-party providers or with telemetry off to start in auto mode when no permission mode is configured, like interactive sessions; --permission-mode still overrides it
Changed Bedrock, Mantle and Claude Platform on AWS requests to a base URL with a non-default port to include the port in the SigV4-signed Host header
Changed the MCP server name widgets to be reserved in cloud sessions and on self-hosted runners: your own server under it, or a close spelling such as widgets_, no longer loads, so rename it
Changed /ultrareview on macOS and Linux to leave symbolic refs out when uploading a local checkout; a checkout whose current branch is a symbolic ref is now refused with an explanation
Windows: Changed project and local settings env to no longer set ALLUSERSPROFILE, SystemDrive, or the CommonProgramFiles variables; set them in user or managed settings instead
Changed /tasks to fold background work Claude Code runs for itself under one “System tasks” row; press Enter on it to show those tasks
Changed /ultrareview on macOS and Linux to require git 2.31 or newer to upload a local repository; checkouts made with --separate-git-dir are now refused instead of being uploaded with an older method
Changed /ultrareview uploads on macOS and Linux to send a partial clone as a working-tree snapshot on git 2.31 or newer, instead of falling back or refusing when git’s version looked too old
Changed /ultrareview uploads on macOS and Linux to refuse, instead of fetching, a partial clone missing some of its working tree’s files on older git versions; a clone made without --filter uploads
Changed Bedrock, Vertex and Mantle start-up model checks to identify themselves as Claude Code, like other Claude Code requests
Changed claude mcp get to hide the command, arguments, and environment values of stdio MCP servers provided by plugins; variable names are still shown
Changed /claude-api so it can no longer be run from Remote Control clients
Changed /config chrome=true to direct you to the /config panel instead of enabling Claude in Chrome by default; /config chrome=false still turns it off when it was on
Changed sandbox settings so project settings cannot widen or turn off an admin-required sandbox, replace the proxy behind a managed deny list, extend a strict allowlist, or reopen managed read-denies
[VSCode] Changed the Manage plugins dialog to ask before removing a marketplace or turning off a plugin that your project’s shared .claude/settings.json turns on
[Cloud sessions] Changed MCP_DISCOVERY_CACHE=1, when set in your cloud environment’s variables rather than a settings file, to reuse your connectors’ tool lists after a session restart; other MCP servers are no longer cached and connect at startup

Show 17 improvements

Improved Claude in Chrome: the native host now reports your computer’s name, so connected browsers can be labeled by computer instead of “Browser 1” / “Browser 2”
Improved Bedrock and Vertex AI sessions to switch to an older available model of the same tier, instead of failing, when an admin removes access to the default model; session titles and summaries now fall back with it
Improved plugin marketplace errors to name why a git address is refused instead of citing enterprise policy
Improved validation of git URLs for plugins, marketplaces and the current repository’s remote
Improved Artifact tool results: they now suggest publishing in the same step as writing or editing the page, which can save a round trip
Improved Remote Control: a /btw side question asked of a session hosted by an app such as Claude Desktop now sees the turn in progress, not only the last finished one
Improved pictures Claude sends as BMP, HEIC, HEIF, AVIF or TIFF files: the Claude apps now show a preview where Claude Code can convert them
Improved subagents in auto mode: a subagent’s run now ends as soon as it hands its report back to its caller, instead of taking extra turns that reach no one
Improved Bedrock and Vertex start-up model checks: models your account cannot use are now remembered for up to a day instead of being re-checked on every launch
Improved Artifact tool publish results to use fewer tokens: the note on updating an artifact is shorter, and where to find your artifacts is no longer repeated after every publish
Improved SDK liveness during a non-streaming fallback request: with partial messages on, a ping stream event is now sent every 30 seconds on the Anthropic API, Claude Platform on AWS and gateways
Improved /resume and claude --resume on a session that is running in the background: they now open that session instead of refusing, and a prompt given with claude --resume <id> "prompt" is sent to it as its next turn
Improved per-turn performance when many permission deny rules and MCP tools are configured
Improved responsiveness when leaving the ctrl+o transcript view in long sessions when fullscreen rendering is off
Improved Bedrock, Vertex and Mantle start-up model checks to send the same User-Agent, x-app and session ID headers as regular requests
[VSCode] Improved the Manage plugins dialog: a failed plugin action now opens a popup that explains it and, where there is one, offers the fix
[Code Review] Improved the Code Review check run to say when your repository’s REVIEW.md wasn’t applied, for example on a very large pull request or when REVIEW.md is a symbolic link

Show 86 bug fixes

Fixed claude -p with CLAUDE_CODE_FORK_SUBAGENT=1: a subagent’s own Agent call now runs in the foreground, so the subagent gets the child’s result
Fixed plugin and marketplace installs and updates over SSH ignoring the ssh program set in GIT_SSH or in your git config’s core.sshCommand
Fixed Claude Code refusing to start when the OS denies reading the managed settings file; it now warns and starts without that file’s policies. Other read errors and unparseable files stop every session
Fixed cloud sessions that restarted after their conversation was compacted refusing the next update to an artifact the session had already read or published
Fixed claude plugin disable and enable with a full name@marketplace id changing a settings entry in another letter case instead of the installed plugin’s own
Fixed files attached to a message sent over Remote Control being left out after a single failed download; a network error, timeout or server error is now retried up to twice
Fixed switching models mid-session with a set_model request (such as the Agent SDK’s setModel) leaving the new model on the built-in output-token limit and auto-compact window until restart
Fixed redacted logs and transcripts showing part of a URL password that contains @, or all of it when the URL writes its @ as %40
Fixed SSH passphrase and new-host prompts from worktree and /teleport fetches taking over the terminal; these fetches now fail fast instead of asking
Fixed switching off an MCP server added mid-session in SDK and -p sessions leaving its tools available
Fixed claude -p --permission-prompt-tool: a background subagent’s permission request now goes to the prompt tool instead of being auto-denied
Fixed claude mcp list and claude mcp get, and the not-found error of claude mcp remove, login and logout, printing line breaks and terminal escape sequences from MCP server names and values
Fixed sandbox auto-allow asking for approval on every run of many inline scripts (python3 -c, node -e) just because they contain =
Fixed fork subagents not keeping the session’s plan mode or dontAsk mode: a fork now runs under its parent’s permission mode and cannot exit plan mode
Fixed claude remote-control --help saying --[no-]chrome defaults to the machine’s /chrome setting; spawned sessions keep Claude in Chrome off unless --chrome is passed
Fixed background subagents in auto mode prompting a second, redundant reply after each report
Fixed cloud session creation and /remote-env reading only the newest 20 of an account’s environments
Fixed Remote Control marking a message as read as soon as it arrived instead of when Claude started on it, and losing a message still queued when the terminal quit (it now arrives on the next resume)
Fixed installing a plugin with claude plugin install or /plugin putting it into an installed plugin’s cache or data folder when their ids differ only in ., -, @ or (macOS, Windows) capitals; the install is now refused
Fixed hooks and SDK permission callbacks seeing a missing or outdated plan on ExitPlanMode when the plan was written in the same response
Fixed the first reply in cloud sessions arriving tens of milliseconds late, a regression in 2.1.283
Fixed sessions that authenticate with ANTHROPIC_AUTH_TOKEN against the Anthropic API never loading the organization’s policy
Fixed a failed agent(), parallel() or pipeline() call that a workflow script awaits later, or not at all, being treated as an unhandled promise rejection, which could end a background session
Fixed synchronous hooks hanging Claude Code while a background process the hook started (for example some-daemon &) kept its output open; the hook now finishes shortly after its own process exits
Fixed WebFetch reporting a rate-limited domain safety check as a network or enterprise policy block
Fixed the fullscreen ctrl+o transcript freezing briefly when opened on turns with hundreds of file reads or searches; tool calls still running when the transcript opens now show their results when they finish
Fixed Amazon Bedrock mid-stream modelTimeoutException and serviceUnavailableException errors showing a raw JSON body instead of the error message
Fixed /autofix-pr and /schedule saying the Claude GitHub App is not installed on a repository whose install status had not been checked yet
Fixed dismissing a row (x) in /artifacts unlinking its file from the artifact, so publishing the same file again created a new artifact instead of updating it
Fixed Artifact tool publishes after a conversation rewind (Esc Esc) overwriting a file’s newer content that Claude had read only in the rewound turns; the publish is now refused until Claude re-reads the file
Fixed an Artifact allow rule (“don’t ask again”) letting the Artifact tool publish a file outside the working directories without asking; add the file’s folder with --add-dir for the rule to cover it
Fixed /cost and SDK modelUsage reporting a turn under the wrong model when the server answered a refusal with a different fallback model than the client expected
Fixed the Artifact tool so that publishing a page no longer lets Claude overwrite its source file without re-reading it when Claude’s earlier read was cut short or the file had changed since
Fixed auto mode skipping its classifier for Artifact tool asset uploads and reads of someone else’s artifact when you had approved that artifact earlier in another permission mode
Fixed a misleading “core.worktree is set” error from /ultrareview when the project folder briefly could not be read
Fixed /ultrareview on macOS and Linux failing to upload the working tree from a git worktree whose per-worktree config sets core.longpaths
Fixed the Artifact tool sometimes reporting a publish as a conflict with another session after retrying a temporary server error, when the first attempt had actually succeeded
Fixed /ultrareview uploads including uncommitted changes to credential files whose name has a colon before the extension, such as server:8443.key
Fixed a rare auth failure when two sessions recover a login refresh lock left by a crashed process at the same time
Fixed the PowerShell tool’s permission check skipping deny and ask rules, and caching that failure for later checks, when its command parser failed to start (for example when the machine was out of memory)
Fixed /ultrareview uploads on macOS and Linux running slowly on some unusual file names, and their credential-file check missing file or folder names with many backup or editor marks
Fixed a cancelled shell command or hook still starting, and running to its end, when the cancel arrived while it was being set up
Fixed vim mode: after editing in the external editor (Ctrl+G), x or r in NORMAL mode no longer breaks a pasted-text placeholder at the end of the prompt
Fixed responses blocked by the API’s output content filter being re-sent and retried, sometimes for minutes, instead of showing the filter’s error right away
Fixed plugins silently skipping a bundled .mcpb MCP server that still needs configuration: /plugin, the install message and claude plugin install now say so and point to Configure
Fixed compacting or resuming a session failing, opening without its history, or crashing when its saved transcript holds a compaction marker or loop wakeup entry with missing or malformed fields
WSL: Fixed /ultrareview refusing to upload a checkout on a Linux volume when a changed file’s name has a colon or ends in a dot or space
Fixed CLAUDE_CODE_RESUME_INTERRUPTED_TURN re-running a turn that had ended at --max-turns
Fixed sign-in that could wait forever after the browser showed success
Windows: Fixed /ultrareview uploading a linked worktree of a repository rooted at your home folder in some cases
Fixed cloud sessions reporting the uploads folder as missing before any file had been uploaded
Fixed a reply sent from claude agents to a background session waiting on a permission prompt sometimes approving the pending command
Fixed claude attach, logs, stop, respawn and rm starting a new session with the command name as its prompt when options came before it, such as from a shell alias
Fixed claude mcp list leaving out WebSocket (ws) MCP servers; each is now listed with its URL and health status
Fixed claude mcp get showing no Type, Command, Args, or Environment for stdio servers whose config entry omits the type field
Fixed .claude/settings.local.json allow rules being held back outside a git repository when git’s trace2 output is configured
Fixed the /claude-api eval runner scaffold and report builder writing through a symlink or hard link planted at an output file
Fixed the /claude-api eval runner scaffold counting responses cut off at max_tokens in the score averages; they are now marked truncated and counted separately
Fixed   showing as literal text in the terminal when a reply uses it to indent text, such as row labels in a markdown table
Fixed a brief freeze (up to a second) partway through long sessions outside fullscreen mode, which came back after /clear or /compact
Fixed an approved Edit never going through when its target is a device, such as a file symlinked to /dev/null, and the approval came from the IDE diff view or changed the edit
Fixed a failing API request being retried up to 21 times when streaming kept failing; the non-streaming fallback now shares the request’s retry budget instead of getting a fresh set of retries
[VSCode] Fixed pressing Enter after typing a slash command running an unrelated menu item picked by fuzzy match, or doing nothing
[VSCode] Fixed an open agent transcript losing the agent’s newer messages during a long session
[VSCode] Fixed a message that quotes a Claude Code or IDE tag losing the rest of its text in the chat
[VSCode] Fixed a message sent while Claude was working disappearing from the conversation after the session was reopened
[VSCode] Fixed the session list’s Web tab showing the previous account’s sessions after an account switch
[VSCode] Fixed restored tabs re-running an interrupted turn when VS Code was started with CLAUDE_CODE_RESUME_INTERRUPTED_TURN set, even with Continue After Reload off
[VSCode] Fixed Escape stopping the running turn instead of closing the command menu after clicking one of its rows
[VSCode] Fixed opening Past conversations replacing a live conversation with its saved copy
[VSCode] Fixed a Claude tab reloaded after an extension restart staying blank instead of saying how to recover
[VSCode] Fixed opening a conversation that is already open in another window or app starting a second copy of it without warning; it now asks first
[VSCode] Fixed a hook’s reason for blocking or stopping a prompt disappearing after a window reload
[VSCode] Fixed tabs stuck on a conversation that can’t be resumed: the error now says so and offers to start a new conversation
[VSCode] Fixed every file Read, Write and Edit stalling for ten minutes and then being skipped when the editor stops responding to the extension’s automatic save before the tool runs
[VSCode] Fixed the agent map labeling a sub-agent with the session’s model instead of the model it actually ran on (e.g. under CLAUDE_CODE_SUBAGENT_MODEL_FORCE or an agent’s own model)
[VSCode] Fixed uninstalling a plugin from the Manage plugins dialog, which removed the wrong installation or failed for a plugin installed for the project
[VSCode] Fixed sign-in staying on the authorization-code step after going back and choosing the same sign-in method again
[VSCode] Fixed the chat panel stalling when a long session trims its oldest rows
[VSCode] Fixed the conversation disappearing from a session when many agents run
[VSCode] Fixed the editor tab keeping an old name after a session was renamed with /rename, by a SessionStart hook, or on claude.ai
[VSCode] Fixed the agent map’s transcript view leaving out messages sent to a running agent
[Cloud sessions] Fixed Run now on a routine showing internal error text when the run is refused before it starts; it now shows the same explanation as the routine’s failure notification
[Claude Tag] Fixed the Default model setting in admin settings and a channel’s Configure page offering models your organization can’t use, which made saves or new sessions fail
[Claude Tag] Fixed the note under Claude’s Slack messages saying it answered on a fallback model, and why, disappearing when Claude later edited that message
[Code Review] Fixed the organization menu in Code Review’s “Add a repository” dialog showing only a few of your GitHub organizations; it now loads more as you scroll

2.1.284

Sun, 27 Sep 2026 16:00:00 GMT

Added

Added Claude Sonnet 5.5 (claude-sonnet-5-5), now the default Sonnet model on the Anthropic API — 1M context, $2/$10 per Mtok with $0.20/Mtok cache reads
Added a “Yes, but ask again next time” answer to auto mode’s prompt before a read outside the working directories, so you can allow that one read and still be asked about later ones
Added dollar amounts to the Claude apps gateway spend limit in /usage and the status line (for example “$271.40 / $500.00 spent this month”) when the gateway runs this version or later; the status line’s rate_limits.spend_limit also gains used_usd, limit_usd and period
Added effortSlider:decreaseEffort, increaseEffort and toggleUltracode keybinding actions, so the /effort slider’s arrow and Tab keys can be rebound in keybindings.json
Added /rate-limit-options to /help and the command menu for claude.ai subscribers, so the usage-limit notices that mention it point to a command you can find
Added /mcp reconnect all in the interactive terminal to retry every MCP server that failed to connect or needs authentication at once
Added Claude apps gateway startup warnings when a managed policy’s availableModels is empty, or leaves out the model Claude Code starts on without setting model or enforceAvailableModels
Added auth: { google: {} } for Claude apps gateway telemetry.forward_to destinations, so telemetry can be exported straight to Google Cloud’s OTLP endpoint using the gateway’s Google Cloud credentials
Added certificate client authentication (private_key_jwt) between the Claude apps gateway and its identity provider, for identity providers that issue certificate credentials instead of client secrets
[VSCode] Added an optional time above each prompt and response, with a date line where the day changes (Claude Code: Show Message Timestamps setting, off by default)
[VSCode] Added plugin load errors and notes to the Manage plugins rows, with a popup to disable, uninstall or copy the error
[VSCode] Added an Ultracode on/off switch under the Effort slider, replacing the slider’s Ultracode stop; the model pill shows ”· Ultracode” at any effort level
[Claude Tag] Added model family choices such as “Opus (latest)” for a thread, a channel default or your DM, so the choice follows the newest model in that family
[Claude Tag] Added the spend that counts toward your organization-wide limit to the analytics spend projection chart, with how much of the limit is used

Changed

Changed interactive terminal and VS Code sessions to start in auto mode when no permission mode is configured, on every plan and provider; permissions.defaultMode still overrides it
Changed Ultracode into its own toggle in /effort (Tab, or /effort ultracode [on|off]): it no longer forces xhigh effort and stays on at any effort level
Changed retries after a dropped connection mid-response to share one budget with the rest of the request’s retries, so a failing request gives up sooner
Changed the notice shown when a Sonnet model’s safeguards flag a message to explain why it happened and to offer editing and retrying
Changed safety-related model switches in sessions that pin an Opus model with ANTHROPIC_DEFAULT_OPUS_MODEL or modelOverrides: on the Anthropic API, the API now picks the model to switch to for each kind of flag, not the pinned model
Changed the non-interactive first turn to still wait up to 2s for connecting MCP servers named by --allowedTools or an mcp_tool hook, even when CLAUDE_CODE_MCP_STARTUP_WAIT_MS is 0
Changed /recap to decline with a short notice when it arrives relayed from a chat thread (your own included) or from a routine or webhook; typed in the terminal, the Claude apps, Remote Control, -p or an SDK host, it runs as before
Changed /artifacts to show its filter tabs beside the title with one-word labels (All, Mine, Shared), using the same tab bar as /config and /plugin
Changed artifact publishing to refuse a file on a network share (a \\host\share path or a /net automount) unless it is on a mapped network drive added with --add-dir
[VSCode] Changed CLAUDE_CONFIG_DIR in the claudeCode.environmentVariables setting to apply only when it is an absolute path, and passed it to terminals that continue the chat
[Claude Tag] Changed Claude to post its private sign-in notice at every @mention from someone who hasn’t connected their Claude account, instead of going quiet after the first

Show 18 improvements

Improved the usage-limit wait: the limit’s state and the countdown with the usage-credits option now show as one block under the prompt, and limit messages no longer repeat the countdown
Improved the “No such tool available” error for Claude in Chrome tools called without their prefix: it now names the tool to call
Improved Monitor event rows to show what each event printed instead of repeating the description, and stopped repeating an unchanged “Waiting for N … to finish” line after every event
Improved Workflow tool sandbox hardening for errors thrown by async script hooks
Improved startup time and memory use by building only the parts of the settings schema that your settings files actually use
Improved /claude-api: hillclimb no longer spends rounds on prompt rewordings too small for the eval to measure, and an extra page you ask for beside report.html is built as one local file that loads nothing from the network
Improved lists such as /tasks, /copy and /hooks: the details after each name now line up in one column when they fit, and otherwise sit at the right edge
Improved claude plugin marketplace add to say when it replaces a marketplace already added under the same name from a different source, and how to undo it
Improved the startup refusal when managed settings require a sign-in (forceLoginMethod or forceLoginOrgUUID) and an API key, token or apiKeyHelper is configured: it now names the credential in use, where it is set, and how to remove it
Improved auto-memory loading: invisible characters and tags that imitate Claude Code’s own markup are neutralized in MEMORY.md and recalled memory notes before they reach Claude
Improved claude remote-control: in a folder you haven’t trusted yet, it now asks for workspace trust on the terminal instead of exiting
Improved artifact pages: Claude writes its design plan into the page instead of the reply, and uses the name you already gave something as the page title
Improved the Artifact tool so that when Claude is given a claude.ai chat or project link, an artifact from a chat, or an artifact id on its own, it asks for the right link or the content instead of stopping
[Claude Tag] Improved “Notify members now” in admin settings: one press reaches every workspace your organization claimed in an Enterprise Grid, and more members in large workspaces
[Claude Tag] Improved Claude’s wait notice on self-hosted environments with on-demand runners: it now says whether a runner is starting, a start will be retried, or no runner will start
[Claude Tag] Improved the error shown when adding a channel manager fails because the channel’s Slack workspace can’t be confirmed as connected to your organization
[Claude Tag] Improved a channel’s access lists in admin settings to show the connectors, repositories and plugins an auto-join pattern attaches, and where each comes from
[Claude Tag] Improved adding repositories as a channel manager: when your GitHub sign-in can’t confirm you’re a repository admin, the page asks you to sign in with GitHub

Show 57 bug fixes

Fixed a damaged response stream showing raw errors such as “JSON Parse error” or “undefined is not an object”, or writing the word “undefined” into an answer, instead of being retried or reported as an interrupted response
Fixed an overloaded or server error arriving right after a thinking block ending the turn with an error instead of being retried
Fixed “Prompt is too long” errors that persisted after compacting: when the compacted request is still too long, Claude Code now compacts once more, keeping less of the recent conversation
Fixed a session whose model is unavailable, with no fallback model left, showing a bare “is currently unavailable” message (or “Something went wrong” in cloud sessions) instead of the model-unavailable notice and its Learn more link
Fixed Agent SDK sessions crashing when a user message contains an image with a malformed source, and failing on every later turn after a malformed document block; a malformed image is now replaced with an explanatory note
Fixed MCP tool calls in a resumed session failing with “No such tool available” while their server was still connecting; the call now waits up to 10 seconds for the server
Fixed repeated calls to the plan-usage endpoint after it rate-limits or rejects your login: /usage, /extra-usage and IDE usage views now back off instead of re-asking
Fixed claude mcp add reporting success when managed settings restrict MCP servers to plugins; it now refuses and says what to do, instead of saving a server that never loads
Fixed the /plugin configure screen: boolean options are now a true/false choice instead of free text, number options refuse invalid input, and ←/→ change an options field instead of switching tabs
Fixed ANTHROPIC_FOUNDRY_RESOURCE being interpolated into the Foundry endpoint host unvalidated; a value that is not a plain resource name is now refused
Fixed Claude Desktop behind a Claude apps gateway offering no 1M context option: the gateway now marks each 1M-capable model for Desktop automatically
Fixed ↓ in shell mode selecting a hidden background-tasks pill, which stopped Backspace and Ctrl+U from editing the prompt
Fixed Bash tool failing on Windows with many plugins enabled: plugin bin/ directories that don’t exist are no longer added to PATH, and inherited entries aren’t added twice
Fixed sparsePaths plugin marketplaces cloning empty and replacing a working local copy on older git (before 2.39), which failed every refresh with “marketplace.json file is no longer present”
Fixed fullscreen rendering erasing the terminal output above the session when [ in transcript mode writes the conversation to scrollback (macOS and Linux)
Fixed fullscreen scroll position jumping to the previous message or to the bottom when a reply finished streaming while scrolled up
Fixed tab bars in dialogs such as /config and /plugin breaking the title and tab labels mid-word in a narrow terminal; a tab that doesn’t fit now moves to the next line whole
Fixed the /model picker showing “+1 model” below the list after scrolling to the last model; the count now covers only the models below the visible rows
Fixed /keybindings writing Backspace and Delete bindings for a footer action that does nothing into the generated keybindings.json
Fixed a rebound agent panel close key (footer:close) typing “x” instead of itself on the row of the agent you’re viewing
Fixed vim mode . not repeating text typed very fast (for example over ssh or in tmux) or pasted without bracketed paste, and leaving the prompt in INSERT mode after repeating a change with nothing typed (such as cw then Esc)
Fixed vim mode leaving the cursor on an image placeholder’s opening bracket after dd on the last line or yy at the end of the prompt, where r or x would break or delete the image
Fixed a key pressed the instant the terminal regained focus answering the Remote Control enable prompt before its short safety delay restarted
Fixed the workspace trust dialog appearing a second time after switching renderers or updating when Claude Code was started in the home directory
Fixed rules symlinked into .claude/rules from outside the project being skipped without ever showing the external-imports approval prompt; a .claude directory symlinked from outside the project now asks for the same approval
Fixed plugins from marketplaces, claude.ai and npm pre-approving their own tools via allowed-tools under managed allowManagedPermissionRulesOnly; only plugins from an official Anthropic source or a source that managed settings vouch for keep that pre-approval
Fixed a failed first claude plugin install leaving the plugin enabled and recorded when a dependency’s version range could not be met
Fixed the debug log dropping a failed hook’s stderr when the hook also wrote to stdout, and logging nothing for a failed hook with no output; failed hooks now also log their status code
Fixed {"decision":"block"} returned by Elicitation and ElicitationResult hooks being ignored; it now declines the MCP elicitation, as exit code 2 does
Fixed sessions launched without the SendMessage tool (such as by Claude Desktop) still being told to message other sessions with it
Fixed a photo sent from the Claude app over Remote Control being lost when its queued message was pulled back into the terminal prompt to edit, and the cursor moving one character for a photo with no caption
Fixed typing a message during an automatic usage-limit wait taking the wait out of the “Continue automatically at usage limit” setting’s control when that turn hit the limit again
Fixed usage-limit warnings suggesting /upgrade to users already on the highest Max plan; the warnings and /upgrade itself now point at /usage-credits when it is available
Fixed the Explore subagent switching to Opus on the Claude API when the session runs a model ID Claude Code doesn’t recognize, such as a custom model behind a proxy; Explore now inherits that model
Fixed /loop status updates in self-paced mode often not being shown because Claude wrote them only in its reasoning; Claude now writes each update, and the outcome when the loop stops, as visible text
Fixed /ultrareview failing to upload the working tree when started from a git worktree that the Claude desktop app created on macOS or Linux
Fixed sandboxed Bash commands failing to start on Linux when the working directory is write-denied and contains a read-denied directory
Fixed artifact database write results telling Claude that every viewer sees a write to a viewer’s private data/users/ subtree, and added a “view” level to as_level
Fixed the Claude apps gateway answering 431 Request Header Fields Too Large to every request from a sign-in whose identity provider lists many groups; it now accepts request headers up to 256 KiB
[VSCode] Fixed Reload Claude from the Memory dialog restarting before an edited file was saved
[VSCode] Fixed a restored tab opening a conversation another Claude process still has open; it now asks first
[VSCode] Fixed Focus view sections you expanded closing on their own while a sub-agent is working or when the section’s first step is trimmed from view
[VSCode] Fixed typing /model and Enter printing usage text into the chat instead of opening the model selector
[VSCode] Fixed /feedback on Vertex, Bedrock and Foundry being refused after you pressed Send; the report is now saved on this computer, as the terminal does
[VSCode] Fixed sign-in waiting up to a minute for the Python extension after a window reload
[VSCode] Fixed Claude Code tabs that stopped responding after Restart Extensions: they now reopen on their conversation
[VSCode] Fixed a message from another agent with no recorded sender showing as raw XML in the chat
[VSCode] Fixed messages from other agents, sessions or channels disappearing after a reload
[VSCode] Fixed a user’s own /mcp, /config or /settings command being shadowed by the extension’s dialog
[VSCode] Fixed Escape stopping every background agent when no turn was running
[VSCode] Fixed plugin install links replacing a marketplace you already have that uses the same name
[VSCode] Fixed “Prompt is too long” errors after compaction when a large text file is attached to a message
[VSCode] Fixed chat links to files with non-ASCII characters, spaces or brackets in their path not opening
[Cloud sessions] Fixed a routine’s Edit and Duplicate controls saying the routine was still loading while you were offline; they now tell you you’re offline
[Claude Tag] Fixed the earlier Claude in Slack app’s progress card and link previews omitting the repository and Create PR button when a GitHub Enterprise host name contains an underscore
[Claude Tag] Fixed Claude staying silent in a channel whose environment declines to start it; it now posts one notice asking you to contact an admin, and retries when @-mentioned
[Code Review] Fixed Code Review giving up without posting a finished review when an unsubmitted review under its GitHub App was open on the pull request; it now retries the post first

2.1.283

Thu, 24 Sep 2026 16:00:00 GMT

Added

Added x-claude-code-prompt-id to the gateway hint headers so LLM gateways can group the requests that serve one user prompt; opt in with CLAUDE_CODE_GATEWAY_HINT_HEADERS=1
Added availableModelsMatch managed setting: with "exact", an availableModels entry allows only the model version it names, so new releases stay blocked until listed
Added deniedModels managed setting to block specific models, even when availableModels allows them
Added MCP tool, WebFetch and WebSearch outputs to the tool.output OpenTelemetry span event when OTEL_LOG_TOOL_CONTENT=1
Added /doctor prompt-audit (also /checkup prompt-audit) to audit your CLAUDE.md files, skills, agents and commands for prompting patterns written for older models
Added click-to-expand for truncated messages from your other sessions in fullscreen mode
Added path to --plugin-dir load-failure entries in the stream-json system/init plugin_errors, naming the directory that did not load
Added an opt-in load_test_mode block to the Claude apps gateway config: requests are built and signed but not sent upstream, and clients get a canned reply, so a deployment can be load tested
Added a mantle upstream provider to the Claude apps gateway for Amazon Bedrock’s Mantle endpoint
[Claude Tag] Added a “Channels Claude can search” admin setting that limits Claude’s Slack search to public channels it has been added to, set per organization, workspace or channel
[Claude Tag] Added a Back to Slack button on the page shown after connecting your Claude account, returning you to the thread you started from

Changed

Changed interactive sessions on third-party providers or with telemetry off to start in auto mode when no permission mode is configured; permissions.defaultMode still overrides it
Changed the /ultrareview launch dialog to say that reviewing a local branch may upload uncommitted changes to tracked files
Changed the /model picker’s Opus row and the Default model’s name to drop “(1M context)” where Opus already has a 1M context window; the window is unchanged
Changed prompt suggestions in the terminal to appear less often after 20 in a row go unused; using one brings them back
Changed --system-prompt and --append-system-prompt to accept their text and -file forms together; the file’s text comes first
Changed Skill(anthropic-skills:<name>) deny rules to also block that skill when Claude Desktop delivers it as a plugin, and Skill(skill:<name>) denies to match the skill’s alias and display name
Changed /rewind and /diff lists to move on the same keybinding actions as every other list (select:*); messageSelector:*/diff:* rebinds still work
Changed the /workflows run list to size itself like other lists: half the terminal inline, and it keeps its title on screen when the prompt shows below
Changed claude plugin eval to require git 2.31 or later when git is installed; a run on an older git is refused with a message naming the version
Changed artifact watching: a watch that was armed automatically (not one you asked for) now ends after 3.5 hours with no activity; publishing or watching the artifact again re-arms it
Self-hosted runner: Changed lifecycle hooks’ git to skip a repository’s Git LFS pre-push hook, ignore a writable system core.hooksPath, and not sign commits without --configure-git
Self-hosted runner: Changed GIT_SSL_CAINFO and GIT_SSL_NO_VERIFY under Anthropic-managed git: the runner’s own git always verifies Anthropic’s git route, and warning lines say what applies where
Reverted the 2.1.282 reservation of the claude-ai name: skills, commands, workflows and MCP servers’ skills and prompts so named load again, and Skill(claude-ai:*) rules are ordinary prefix rules
[Cloud sessions] Changed new routine schedules to default to a few minutes past the hour, with a note that routines set exactly on the hour can start several minutes late

Show 16 improvements

Improved the /mcp tool list: it shows more tools at once, scrolls with the page keys and mouse, and marks tools your organization blocked with a warning icon
Improved MCP tool results: images returned by MCP tools are now also saved to a file, so Bash, Read and other tools can open them
Improved /tasks: rows show a status icon, the name and whole facts, the title and key hints stay on screen with many tasks, and the list gains paging keys, the mouse wheel and clicks
Improved lists in /help, /hooks, /copy, /chrome, /memory, /ide, /release-notes, /rewind, /diff, /remote-env, /plugin and other pickers with page keys, mouse wheel and clicks
Improved lists beside a search box, such as /skills and /artifacts, to draw their pointer dim while the search box has the keys, so only one pointer is highlighted
Improved the compaction spinner: its timer now starts when compaction begins and it counts the summary’s tokens as they stream, replacing the percentage bar
Improved the browser page shown after signing in to an MCP server: centered layout, dark mode, and new artwork
Improved the Skill tool’s reply when a skill belongs to a plugin that failed to load, so Claude tells you the plugin could not be loaded instead of calling the skill uninstalled
Improved prompt-audit on Claude Code configuration: stale paths, stale commands and contradicting instruction files now lead the report, and thinking keywords that Claude Code documents are kept
Improved recovery from an installed_plugins.json that cannot be read at all: its contents are kept in a file beside it before it is rebuilt, and claude plugin list names that file
Improved artifact database reads: an ordered query that returns a full page now says it is one page and how to read the rest
Improved first-reply latency: a pattern-compile step that ran at the end of a session’s first reply now runs while the reply streams in
Improved first-request latency by reusing the preconnected API connection
Improved startup: claude -p and Claude Code Remote no longer load the interactive UI, and the auto-mode classifier’s rules and the Artifact tool load on first use instead of at launch
Improved startup for claude.ai accounts whose Artifact tool features aren’t known yet, as on a first run: the prompt no longer waits up to 1.5 s to check them; the first message waits if needed
[Cloud sessions] Improved adding a repository to a running cloud session: a private repository your GitHub account can read but not push to now attaches for reading

Show 53 bug fixes

Fixed SDK sessions losing a deferred tool call or finished tool result when a turn ended early, a held approval prompt after a worker restart, and a non-streaming fallback’s result.usage
Fixed MCP progress notifications being discarded once a long-running tool call moved to the background; the background task now shows the latest progress
Fixed stdio MCP servers being left running when the session ended while they were still starting
Fixed a brief HTTP 404 from a stateless remote MCP server (for example a proxy mid-redeploy) leaving that server unusable for the rest of the session while still shown as connected
Fixed MCP sign-in for a server with no valid URL failing with an opaque SDK error; /mcp no longer offers Authenticate for such servers
Fixed the weekly Fable limit not appearing in /usage and the VS Code usage meters when telemetry is disabled
Fixed /model accepting Sonnet 4.6 or Sonnet 5 with [1m] when the id carried a date or -v1:0 suffix, in the cases where the plain id was refused
Fixed /model picker showing a hardcoded Haiku version and price when ANTHROPIC_DEFAULT_HAIKU_MODEL pins a different model
Fixed dynamic workflows started during a model fallback running every agent on the fallback model instead of retrying the configured model
Fixed DISABLE_PROMPT_CACHING_HAIKU having no effect when Haiku is the session’s main model
Fixed claude plugin validate saying Claude Code accepts a plugin or marketplace name it cannot install; such names in marketplace.json now fail validation
Fixed claude plugin validate passing plugins whose outputStyles, themes, monitors, or lspServers paths are missing or point outside the plugin directory
Fixed claude plugin details showing 0 MCP servers for plugins that declare their servers in plugin.json
Fixed claude plugin marketplace remove not saying which installed plugins it uninstalled with the marketplace; it now lists them
Fixed claude plugin uninstall removing the other of two installed plugins whose ids differ only in case, with its options and secrets, when the one named had no enabledPlugins entry at that scope
Fixed plugins that declare no version being silently restored at their source’s newest commit, not the installed one, when their cached files were missing
Fixed user-installed plugins and marketplaces failing to load with “cache-miss” after the home or config directory was moved, for example in bind-mounted devcontainers
Fixed installed_plugins.json showing no plugins when it holds a record under an invalid plugin id; such a file loads again
Fixed installed_plugins.json being rewritten, losing records, when it holds a record this version cannot read; claude plugin commands now name the record and say how to recover
Fixed permission dialogs in screen-reader mode reading quoted commands and paths as if they were the dialog’s own text
Fixed /context not counting MCP server instructions: they now appear as their own row and count toward the total
Fixed markdown links in the Warp terminal rendering as plain text instead of clickable hyperlinks
Fixed claude mcp add, add-json, and remove reporting success when the user or local config file could not be written, for example inside a sandbox
Fixed the first words of a reply in a cloud session sometimes appearing late instead of streaming as Claude writes them
Fixed Claude’s built-in keybindings guide saying chords time out after 1 second instead of 3, and calling cmd an alias of meta, which could produce cmd+ shortcuts most terminals never send
Fixed keybindings.json silently accepting a misspelled modifier such as ctl+k; it now warns in the debug log and suggests the fix
Fixed footer hints still saying “Enter to view” after footer:openSelected was rebound or unbound in keybindings.json
Fixed keys typed quickly together (type-ahead, key repeat, bursts over ssh or tmux) sometimes being handled against stale state
Fixed worktree checkouts failing certificate verification (for example on Git LFS downloads) when the CA certificate is passed to git as GIT_CONFIG_COUNT environment pairs
Fixed sandboxed git asking credential helpers to store the sandbox proxy’s login, which printed “failed to store”
Fixed managed sandbox settings being ignored entirely when one nested value was invalid; the invalid value now fails closed and the rest of the block still applies
Fixed Claude’s edits to its own auto-memory notes being blocked as sensitive-file writes when Claude Code was started in a subdirectory of a git repository
Fixed Remote Control being unavailable on paid plans when telemetry is turned off with DISABLE_TELEMETRY or DO_NOT_TRACK
Fixed the /remote-control menu cutting its QR-code hint mid-word in narrow terminals
Fixed vim mode . dropping a Shift+Enter newline, leaving the cursor inside an accented letter, and repeating an older change after 3J or Visual-mode J on the last line
Fixed vim mode cursor placement: recalling a prompt over 10,000 characters in normal mode no longer leaves the cursor past the end, and V then p now lands on the first non-blank
Fixed vim mode J joining lines with different spacing than Vim (such as a space before ) or after a tab), and 3J or Visual-mode J on the last line not moving the cursor as Vim does
Windows: Fixed the PowerShell tool letting cmd /c rd, rmdir, del or erase delete drive roots, the home folder and other folders that Remove-Item refuses
[VSCode] Fixed the permission mode indicator showing Default while the session kept running in auto or bypass mode after an automatic switch out of it failed; the switch is now retried until it lands
[VSCode] Fixed a session teleported from the web dropping the messages sent while Claude was working
[VSCode] Fixed a Web session staying hidden from the session list, and an empty chat opening in its place, when an older version had saved an empty local copy of it
[VSCode] Fixed a reopened session splitting a turn at a message Claude received mid-turn, such as an automatic continuation
[VSCode] Fixed a reloaded session showing a rewound-away turn, or only the rows before a compaction
[VSCode] Fixed the footer’s agents pill drawing its icon off-center, with the status dot against the edge, in narrow panels
[VSCode] Fixed the chat input showing its text slightly below the cursor and selection after pasting lines that end with a line break into a long prompt
[Cloud sessions] Fixed cloud sessions occasionally redoing an already-finished step, such as posting a duplicate comment or push, after recovering from a server-side restart
[Claude Tag] Fixed a channel’s configure page listing no connectors or plugins when the channel gets its access bundle through an attach rule; rule-attached bundles are now shown
[Claude Tag] Fixed access-bundle repository search missing repositories on GitHub App installs that are limited to a large list of selected repositories
[Claude Tag] Fixed Claude occasionally posting the same reply twice when a new message interrupted it mid-reply
[Claude Tag] Fixed channel routines that stopped running in older private channels whose Slack channel ID changed, for example after a Slack Connect share
[Claude Tag] Fixed conversations in a channel set to “Channel only” all ending when a non-guest member joined and Slack was slow to confirm their membership
[Code Review] Fixed “@claude review” requests going silent when GitHub failed to return the pull request: the request is retried once, and a comment explains if it still fails
[Code Review] Fixed billing for a review that stopped at its time limit with nothing verified: it now shows as incomplete, isn’t charged, and is retried once

2.1.282

Wed, 23 Sep 2026 16:00:00 GMT

Added

Added a maxProseWidth setting that caps the width of Claude’s prose in wide terminals while tables and code blocks keep the full width
Added a startup notice, and /status and claude doctor entries, listing telemetry variables in a project’s settings files that were ignored or that turned telemetry off
Added the allowClaudeInChromeWithManagedMcp managed setting to let claude --chrome run alongside an exclusive managed-mcp.json; the error shown when Chrome is blocked now names it
Added store.readiness_grace_seconds to the Claude apps gateway so /readyz can stay ready through a short Postgres outage such as a database failover
Added a scrollbar to the /feedback drafts list in fullscreen mode; it appears while the mouse is over the list
[Cloud sessions] Added Claude GitHub App status to Settings › Connectors › GitHub: whether the app is installed and reachable for your account, plus steps to connect, install or reconnect
[Cloud sessions] Added “Open repository” and “Open compare page” links to the repository menu of a cloud session whose repository is hosted on a Git server other than GitHub
[Cloud sessions] Added attaching a repository from a different GitHub owner, such as a fork’s upstream, to a running cloud session that already has one, including sessions started from Slack

Changed

Updated the claude-api skill: pre-output refusal billing now links to the How refusals are billed docs, mid-stream refusals bill at normal rates, and pre-output refusals count against rate limits
Updated the claude-api skill to recommend ant apply for keeping Managed Agents resources as version-controlled files
Changed auto mode to use the server-side classifier by default on a direct Anthropic API connection when telemetry is off (CLAUDE_CODE_AUTO_MODE_SERVER=0 opts out)
Changed sandbox.excludedCommands to ignore project and local settings entries when managed settings or --settings set allowUnsandboxedCommands: false, or managed allowManagedDomainsOnly: true
Changed project and local settings to ignore OpenTelemetry variables that turn on export, set its endpoint, or capture content, like CLAUDE_CODE_ENABLE_TELEMETRY and OTEL_LOG_*
Changed Windows/WSL managed settings so an admin policy that is present but invalid or unreadable (HKLM, managed-settings.json) keeps user-writable HKCU and WSL /etc/claude-code from applying
Changed Skill(anthropic-skills:*) and Skill(claude-ai:*) allow rules to cover only skills synced from claude.ai, not plugins or other skills that merely use such a name
Changed skill folders, command files and workflow commands in the anthropic-skills or claude-ai namespace to no longer load; a plugin so named still loads but yields name ties to synced skills
Changed MCP servers configured under the name anthropic-skills or claude-ai to list no skills or prompts (their tools still work); rename the server in your MCP configuration to list them again
Changed the ultracode visuals in /effort and the prompt input to plain styling (no ripple, border flourish or keyword glimmer) and removed the dynamic-workflows spinner tip
Changed the Clawd mascot’s feet in the start-up banner to sit under the corners of his body
[Claude Tag] Changed the bordered cards Claude uses in Slack replies for plans, tables and details to render wide by default instead of a narrow width
[Claude Tag] Changed newly connected Slack workspaces to follow the current default model instead of keeping whichever model was the default when they were connected

Show 6 improvements

Improved the time to resume very large sessions, including ones that were never compacted
Improved the error shown on Windows when a session can’t be resumed because its transcript file could not be read (EBADF): it now names possible causes and what to try
Improved the Claude Desktop unknown-model error to suggest switching to a different model
Improved rendering of unusual Unicode in permission prompts
Improved /artifacts: titles line up in one column, details are dropped whole instead of cut mid-word, and the list supports PgUp/PgDn, Home/End, the mouse wheel and clicks
[Cloud sessions] Improved how quickly the Routines page and the sidebar’s Scheduled list load for accounts whose past sessions scheduled many check-in reminders

Show 59 bug fixes

Fixed every request failing with a 400 error in conversations whose history holds web search results the API cannot decrypt (for example, from a turn answered through a third-party gateway)
Fixed more cases of continued or resumed sessions (--continue, --resume) re-sending earlier messages in a changed form, which could make the API drop Claude’s earlier reasoning
Fixed earlier extended thinking being dropped when /model, /rename, /artifacts or another immediate slash command was used while Claude was working
Fixed continued or resumed conversations losing earlier extended thinking when relaunched with a --tools list that leaves out a built-in tool offered earlier in the conversation
Fixed sessions failing on every turn with an “Invalid data in redacted_thinking block” API error; Claude Code now drops the conversation’s thinking blocks and retries once
Fixed compaction failing when the summarization request is refused; it now retries on a fallback model
Fixed a failed turn (“Effort ‘xhigh’ isn’t available with thinking turned off”) after a safety-related model switch in sessions with thinking off and effort above high
Fixed an unanswered Fable usage-credits prompt switching models in SDK-hosted sessions such as Claude Desktop; the turn now ends instead, and Remote Control clients now see the model-switch notice
Fixed /model with a full Fable model id stopping at an API error instead of opening the usage-credits prompt when the plan needs usage credits that aren’t turned on yet
Fixed requests failing for up to a minute with an “another Claude Code process is refreshing it” login error after that other process was closed or killed mid-refresh
Fixed sessions started while another Claude Code window was refreshing the sign-in (common with several VS Code windows) not retrying their organization policy fetch
Fixed CLAUDE.md and rules being read at startup through a repository symlink reaching macOS’s /Network via .. or a /.vol-style kernel path, or a rules link to macOS’s /home being listed
Fixed Bash permission rules with a mid-pattern :* being skipped in settings files while --allowedTools honored them; they now work from every source, with a startup warning on how they match
Fixed a command approved on a restored permission prompt running twice when a remote session’s worker restarted
Fixed managed settings ignoring a mistyped value for boolean lock keys such as disableClaudeAiConnectors or allowManagedPermissionRulesOnly; the lock now applies and startup names the key
Fixed managed permissions, autoMode, worktree and attribution settings being ignored entirely when one nested value was invalid; the rest of the block now still applies
Fixed repository, user and --add-dir skills, commands and skills-directory plugin manifests pre-approving their own tools via allowed-tools under managed allowManagedPermissionRulesOnly
Fixed safeguard block messages on Amazon Bedrock and Bedrock Mantle not showing a request ID; block messages now also show the message ID
Vertex AI: Fixed web search not being offered for models Claude Code doesn’t recognize yet, such as newly released ones
Fixed Bash and PowerShell hiding a full disk quota behind “Exit code 1” and leaving large output files in temp
Fixed tool input validation errors naming only an unknown, missing or mistyped parameter when other parameters in the same call were also invalid; those are now listed too
Fixed pasted multi-line text being submitted line by line after the terminal’s bracketed paste mode was reset mid-session
Fixed the prompt’s example text flashing and disappearing at startup in projects with a SessionStart hook
Fixed a blank screen flashing before the first frame when starting in fullscreen mode
Fixed garbled, misplaced rows in the non-fullscreen renderer after the screen got shorter while still taller than the terminal, e.g. deleting a prompt line while a shell command streams output
Fixed a stale character left in the last column of a diff when a redrawn line’s CJK character or emoji wrapped to the next row
Fixed the cursor landing before the end of a prompt recalled from history when the prompt contains a tab
Fixed the send-now hint showing ctrl+enter on terminals that send it as a newline (Windows Terminal before 1.25); it now shows ctrl+x ctrl+s there
Fixed claude remote-control --debug failing with “Unknown argument: —debug”, although Remote Control’s own eligibility error says to run with --debug
Fixed /install-github-app saying “cancelled” and then still pushing the branch and saving the API key secret; leaving now stops the remaining steps and reports what was already done
Fixed /feedback, /bug and /share on Bedrock, Vertex and other third-party providers still saving the report file after you cancelled during the save
Fixed plugin uninstall reporting success and deleting the plugin’s saved options when its settings file still enabled it or could not be read; it now stops and names the file
Fixed plugin uninstall deleting a plugin’s saved options and secrets when the list of installed plugins could not be read after the removal; they are now kept and the uninstall says so
Fixed a key typed right after / in /skills moving the skill list instead of reaching the search box
Fixed the terminal cursor jumping from the /skills search box to the skill list while typing, which could hide the caret and put IME input in the wrong place
Fixed lists with a scrollbar, such as /skills and /mcp, being two columns narrower outside fullscreen mode, where the scrollbar can never appear
Fixed the agent panel footer wrapping onto two lines with long rebound keys, and its “Esc to collapse” hint ignoring a rebound collapse key
Fixed a doubled · separator in the /tasks dialog footer when the stop-all-agents shortcut is unbound in keybindings.json
Fixed artifact publishes failing when Claude gave the version a label longer than 60 characters; the label is now shortened
Fixed screen-reader mode, quoted lists and very long lists dropping the blank lines at the top of a code block that opens a list item, directly or inside a quote
Fixed PDF page-read error messages: paths with accented or non-Latin characters now appear readably, and a folder named like “password” or “invalid” can no longer make the error name the wrong cause
Fixed vim mode >> indenting empty lines, r with a count longer than the line changing text, 2J joining one line too many, and a count on the last line (2dd, 2>>) shifting or deleting it
Fixed vim mode cursor placement: after dd, dj, dG or a whole-line p/P it lands on the first non-blank, yy no longer moves it, and Esc after an emoji no longer leaves it inside the emoji
Fixed vim mode ignoring a count typed before . when repeating x, s, p, d or c, and whole-line p/P, o, O, J, >> and << acting on the wrong line when a line above wraps
Fixed vim mode leaving the cursor past the end of a prompt recalled from history or pulled back from the queue in normal mode, so x did nothing
[VSCode] Fixed long replies falling behind the stream: the panel no longer re-parses the whole reply on every update
[VSCode] Fixed the dictation mic button covering the message input’s scrollbar when the input is tall enough to scroll
[VSCode] Fixed Remote Control sessions started on this computer not opening from their Web entry in the session list; they now open the local conversation unless it’s running elsewhere
[VSCode] Fixed an editor tab’s sign-in screen hanging silently after the extension host restarts; it now shows the “stopped responding” notice too
[Cloud sessions] Fixed the next run time shown for an hourly routine being 30 minutes off for people in half-hour-offset time zones such as India
[Claude Tag] Fixed auto-join channel patterns saved for one workspace in Claude Tag admin settings being ignored on an Enterprise Grid org-wide install; Claude now joins matching new channels
[Claude Tag] Fixed Claude not responding in an Enterprise Grid channel shared between two workspaces of one organization when the channel’s Claude Tag version was saved from the other workspace
[Claude Tag] Fixed the earlier Claude in Slack app’s progress card for sessions on a GitHub Enterprise Server repository: it now names the repository and offers a working Create PR button
[Claude Tag] Fixed Slack threads whose model has been retired falling back to another model on every reply, slower and with a fallback note each time; the thread now moves to a working model
[Claude Tag] Fixed files Claude uploads to Slack not being able to carry a caption containing a table; captions now render with the same formatting as replies
[Claude Tag] Fixed Claude’s threads in Slack’s Agents & tools view sometimes being listed under their first message instead of their name; later renames now update the list too
[Claude Tag] Fixed removing a GitHub organization’s grant from an access bundle’s Repositories tab in Claude Tag admin settings failing to save after that GitHub organization was disconnected
[Claude Tag] Fixed Claude always replying “Couldn’t check this channel just now” in a channel shared with a Grid workspace it isn’t added to; the notice now says which workspace needs the app
[Claude Tag] Fixed the cost and token totals in Claude’s reply footer reading many times too high after the session’s cloud worker restarted

2.1.281

Tue, 22 Sep 2026 16:00:00 GMT

Added

Added Claude apps gateway support for newer Claude Desktop keys in desktop policy blocks, including blockReadsOutsideWorkingDirectories and disableBypassPermissionsMode
Added assume_role on Claude apps gateway Bedrock upstreams: the gateway calls Bedrock as an IAM role it assumes through STS, in another AWS account if needed, optionally one session per developer
Added guardrail: {id, version} on Claude apps gateway Bedrock upstreams to apply an Amazon Bedrock guardrail to every request sent through them (set it on all Bedrock upstreams or none)
Added telemetry.resource_attributes to the Claude apps gateway config, to put fixed labels on the telemetry of Claude Desktop and /login sessions
Added "attribution": false in settings.json to hide all commit and PR attribution; older CLI versions skip a settings file that holds it, so keep the object form in files shared across versions
Added MCP URL-mode elicitation on 2026-07-28 protocol connections, so servers can ask Claude Code to open a browser-based flow; no waiting dialog is left on screen when the server has no way to confirm completion
Added MCP server checks to claude plugin validate: it reports .mcp.json entries that would be silently dropped at load, undeclared ${user_config.*} references, and insecure URLs
Added an auto mode recommendation to /insights that estimates how many permission prompts auto mode could have handled in your recent sessions
Added a scrollbar to the /skills, /mcp and /plugin Installed lists in fullscreen mode, like the one /workflows now has: it appears while the mouse is over the list and can be clicked or dragged
[VSCode] Added a Continue/Stop prompt in the VS Code and JetBrains panels when auto mode falls back to billed classifier requests, replacing the unanswerable warning line
[Claude Code on the web] Added a Fast mode switch to the composer’s model menu in cloud sessions, shown when your plan includes fast mode and the selected model supports it
[Claude Code on the web] Added a settings shortcut on the GitHub setup tip and a “Troubleshoot GitHub connection” link in the repository pickers, both opening your GitHub connection page
[Claude Tag] Added a short line in the Slack thread after someone presses Stop, naming who stopped Claude’s response and saying to mention @Claude to continue

Changed

Changed send now (ctrl+enter or ctrl+x ctrl+s) to move running tools to the background instead of cancelling the turn
Changed auto mode so that, where its classifier review runs server-side, read-only and sandboxed shell commands also wait for that review and are blocked when it flags them
Changed CLAUDE_CODE_AUTO_MODE_SERVER to also apply on a direct Anthropic API connection: 0 opts out of the server-side auto mode classifier (the local classifier then counts toward usage), 1 opts in
Changed the dangerous rm prompt in --dangerously-skip-permissions and auto mode to wait 2 minutes for an answer, then deny the command with a rewrite hint so unattended sessions keep going (CLAUDE_CODE_DISABLE_DANGEROUS_RM_TIMEOUT=1 turns this off)
Changed AGENTS.md support to also work on Amazon Bedrock, Google Vertex AI, Microsoft Foundry, LLM gateways, and sessions with telemetry disabled
Changed Claude apps gateway to refuse to start when a managedMcpServers entry’s envHelper path starts with \??\ or /??/, a path form current Claude Desktop refuses to run
Changed self-hosted runners to pass system prompts to Claude Code as private files instead of command-line text, so large prompts no longer fail the launch; a wrapper or command hook that appends --system-prompt or --append-system-prompt must switch to --system-prompt-file or --append-system-prompt-file
Changed queued messages to show in the conversation above the spinner instead of under it
Changed the session artifact links under the prompt into one footer pill (⧉ name or ⧉ N) that opens /artifacts, which now lists this session’s artifacts first
Changed the Artifact tool to let Claude load scripts from unpkg.com in artifact pages
Changed hovering a list row in fullscreen mode, including in /config, to tint the row instead of drawing a second ❯ pointer beside the focused row’s
Changed /mcp: each server’s row now starts with its status icon and name, says its state once, and in a narrow terminal drops trailing facts like “managed” before shortening the name
Changed /workflows: each run’s row leads with its status icon and elapsed time, and a narrow terminal keeps the run’s name and time, dropping the agent and token counts first
Changed Remote Control attachment downloads to reuse connections and to skip files already downloaded in the session
Changed MCP resource lists (the resource list tool and @-mention suggestions) to skip MCP Apps UI resources; reading one by URI still works
Changed claude plugin uninstall --json and the /plugin dialog to say a plugin’s data was kept when its folder stays because another installed plugin uses it or install records cannot be read
Changed the background tasks list (/tasks): pressing x on a running /ultrareview now asks for confirmation before stopping the review
Removed the leftover “(removed)” /agents entry from the command menu and /help; typing /agents still explains where the wizard went
[Claude Tag] Changed the routine list Claude gives when asked in a Slack thread to show that thread’s own scheduled tasks by default instead of every routine in the channel

Show 33 improvements

Improved Claude Desktop sign-in and usage-limit error messages to point at the app instead of terminal commands
Improved startup: managed settings and policy fetches no longer retry requests that can never succeed
Improved interactive startup time: git reads, startup telemetry and the Bedrock/Vertex model-upgrade checks no longer run before the first frame
Improved the time to resume long sessions that read many files; the restored file cache now matches the files as they were read
Improved the time to resume very long sessions that have been compacted, most noticeably through the Agent SDK and Claude Desktop
Improved “Prompt is too long” recovery in sessions dominated by one very large first prompt: that prompt is now summarized on its own instead of being left out of the summary
Improved auto mode after resuming a session in a new process: the permission classifier can now reuse its earlier prompt cache instead of rewriting it
Improved the auto mode denial message so Claude treats a denial as covering the outcome, not only the exact command
Improved the dangerous-rm check to also flag a removal at a shell variable followed by a top-level directory name, at a variable derived from the working directory, or at a backslash-only target
Improved sandbox guidance on macOS: when a local dev server can’t bind a port, Claude now points to sandbox.network.allowLocalBinding
Improved --agents to accept the path to a JSON file (with -p) as well as inline JSON, and to allow an empty prompt
Improved /batch to run where a WorktreeCreate hook provides the agent worktrees, not only inside a git repository
Improved plugin hook-failure errors to name the offending plugin, and added a claude plugin validate warning when a shell-form hook leaves ${CLAUDE_PLUGIN_ROOT} unquoted (it breaks on plugin paths with spaces)
Improved the / menu, /skills, /context and the /plugin Installed list to show skills synced from claude.ai by their short name when no other command uses it, not anthropic-skills:<name>
Improved /deep-research reliability on long research briefs by removing unused required fields from the scope step’s output
Improved the writing in published artifact pages: the bundled artifact-design skill now asks Claude for plain, direct prose
Improved artifact publishing on slow connections: large page uploads are now sent compressed
Improved the large CLAUDE.md startup notice to also count instruction files together, so many mid-sized files and @-imports are caught
Improved debug logs to name settings env variables ignored because the session’s launch environment already sets them
Improved keyboard navigation in tabbed dialogs such as /permissions and /usage: ↑/↓ move focus between the tab row and the content, and a list responds to keys only while it has focus
Improved /help and /sandbox: ←/→ and Tab switch tabs from inside a tab’s list, and ↓ on an empty Custom commands tab in /help no longer leaves the keys stuck until Esc
Improved /install-github-app, /desktop, the /permissions auto mode environment prompts, and the /plugin “Add marketplace?” and “Run this command?” prompts: they now use the standard dialog frame with key hints, and Ctrl+C or Ctrl+D cancels them on the second press like other dialogs
Improved the /workflows and /mcp lists: they page (PgUp/PgDn, Home/End) and take j/k and the mouse like other lists, their arrows follow select:previous/select:next rebinds, and x in /workflows stops the run the pointer is on
Improved the /plugin plugin and marketplace details menus and the /remote-control already-connected menu: they now support Home/End and clicking a row
Improved the background workflow row below the prompt: it now shows the name, a progress bar, the agent count on wide terminals, elapsed time, total tokens, and the large-workflow warning
Improved the /plugin Installed list: rows now line up in columns (status, name, type, details) across every section
Improved /skills: each row now leads with the skill’s name, with ✔ or ◯ alone showing on or off, and stays on one line in narrow terminals
Improved narrow list rows (/skills, /workflows, /feedback): a name keeps 20 columns beside its first detail, and details are shown whole or not at all
Improved /diff: a scrollbar shows where you are in a long list of changed files, and long paths no longer wrap their rows
Improved /hooks: a hook’s detail screen now says what kind of hook it is and where to change it, instead of always pointing at settings.json, and the hooks-disabled, safe mode and managed-hooks-only notices each say what is happening in one plain sentence
Improved screen-reader output in /mcp: a disabled server is read as “off” instead of “pending”
Improved the Remote Control confirmation: its options are briefly inactive again after the terminal window regains focus, so a key pressed while switching back cannot answer it
[Claude Code on the web] Improved the file card shown when a cloud session can’t open a file: it now says whether the file no longer exists or the session’s permission settings block reading it

Show 112 bug fixes

Fixed a crash (“unrecoverable interface error”) that could end a session while an API request was being retried
Fixed a turn that could retry indefinitely, ignoring --max-turns, when the model alternated unparseable tool calls and output-limit truncation
Fixed resumed sessions re-sending earlier turns in a changed form (a parallel tool-call turn, an MCP tool call’s input or a tool-search result while its server was still reconnecting, or a tool-search result whose loading turn was interrupted), which could make the API drop the conversation’s prior reasoning
Fixed resuming a very large session sometimes restoring only its last few messages
Fixed a session resumed after a restart during a pending permission prompt sending a different history than before, which broke the prompt cache from that point
Fixed resuming a session that ended during a tool call: Claude now sees the call and is told its outcome is unknown, and a manual resume no longer adds a hidden “Continue” message
Fixed sessions with an earlier advisor result the API could no longer read failing one request every turn and repeatedly losing earlier reasoning; the history is now repaired once
Fixed the prompt cache being lost when an MCP server disconnects mid-conversation, or is still connecting after a resume, while tool search is off (for example behind a proxy or gateway)
Fixed responses cut short by a proxy or gateway that closes the stream cleanly being shown as complete with no warning, and tool calls running twice on duplicated stream events
Fixed responses failing with “Content block not found” when a proxy drops a stream event mid-response; the partial response is now kept, and web search keeps results that already arrived
Fixed an empty completed response being requested twice when the connection dropped before the stream’s final event
Fixed the stop reason being lost when a proxy sends a trailing usage-only frame
Fixed CLAUDE_CODE_RETRY_WATCHDOG sessions failing on the first 5xx or dropped connection after a run of 429/529 waits, and sleeping uncapped and silently on a long Retry-After from a 5xx
Fixed fast mode retrying rate-limited requests back to back when the server sent Retry-After: 0
Fixed a tool that returned an oversized image leaving sibling tool calls unanswered and still running, or ending the turn with no final message
Fixed conversations getting permanently stuck on “tool_use.name: String should have at most 200 characters” after the model called a tool by an overlong name
Fixed tool calls failing with “Failed to get memory usage”, or being reported as failed after they ran, when Claude Code cannot read its own memory usage, for example when it has run out of file descriptors
Fixed --input-format stream-json sessions (Agent SDK, VS Code extension) and scheduled cloud sessions failing every turn with an error when an earlier assistant message had plain-string content
Fixed non-interactive sessions (-p, Agent SDK) failing on the next turn after the directory they were started in was deleted mid-session
Fixed headless sessions with host-side (SDK) MCP servers stalling on the first message when the host stops responding mid-handshake; remote sessions now wait a few seconds at most
Fixed interactive startup waiting on the managed-settings network request (about 80 ms, 17+ seconds when the network is unreachable) when no MCP servers or plugins are configured
Fixed a delay of up to two minutes before responding when reading or @-mentioning a PDF larger than 3 MB
Fixed an interrupted Read of specific PDF pages leaving its page render running for up to two minutes
Fixed permission dialogs and attachment checks reading a path under macOS’s /.vol, /.nofollow or /.resolve (which can reach a network mount) before approval
Fixed a recursive rm whose target is only command-substitution output, such as rm -rf "$(pwd)", running unprompted in auto and --dangerously-skip-permissions mode; it now asks even with a Bash allow rule, unless run with CLAUDE_CODE_DISABLE_SUBSTITUTION_RM_PROMPT=1
Fixed a permission rule containing a NUL byte being expanded into a wildcard match; such a rule now matches nothing
Fixed sandbox excludedCommands entries not matching git rev-parse --git-dir, programs named like shell builtins, and commit messages containing [WIP] or # lines
Fixed sandboxed Bash commands being unable to write to $TMPDIR when CLAUDE_CODE_TMPDIR is set
Fixed claude --bg starting a background session, and running its project hooks, in a directory that had not passed the workspace trust prompt; it now asks for trust first, or exits when not run interactively
Fixed --setting-sources (and SDK settingSources) not being forwarded to spawned sessions: teammates, /bg, claude agents sessions and --worktree --tmux now start with the parent’s restriction
Fixed Read, Write, Edit and NotebookEdit: a file path containing a null byte now fails that tool call with a clear error instead of ending the whole turn
Fixed Write refusing a call that gives the file path or content twice under two parameter names with identical values
Fixed CLAUDE.md and rules files from an --add-dir directory inside the working directory being sent to the model twice in headless and SDK sessions
Fixed remote sessions staying on “needs approval” with a stale prompt after a permission prompt and a sandbox network-access prompt overlapped and both were answered
Fixed cloud sessions not telling Claude about background agents that finished just before a worker restart
Fixed scheduled routine and notification turns in remote sessions not receiving turn-start notices (newly available tools, MCP changes, date, todos) until after the first tool call
Fixed scheduled tasks and /loop wakeups being fired again every second when their delivery failed, which could make Claude Code exit at the end of a turn
Fixed Remote Control reporting “disabled by your organization’s policy” when the org policy simply hadn’t loaded yet; it now retries the fetch and says it couldn’t verify
Fixed the Artifact tool missing from Remote Control sessions that claude remote-control starts for you to open from Claude Desktop, claude.ai or the mobile app
Fixed macOS credential writes dropping stored MCP OAuth tokens or deleting the keychain entry when the login keychain was locked (e.g. right after wake)
Fixed gcpAuthRefresh/awsAuthRefresh login processes being left running (and holding their localhost callback port on Windows) when Claude Code exits or the refresh times out
Fixed the “Not logged in · Run /login” footer and missing claude.ai connectors persisting in a session after logging in from another Claude Code process
Fixed mcp_tool hooks on blocking events (PreToolUse and similar) being skipped while their MCP server was still connecting; they now wait for it, up to the MCP connect timeout
Fixed the same MCP server being connected twice when a plugin or claude.ai connector and a configured server spell its URL differently (host letter case, default port, trailing slash)
Fixed MCP_CONNECTION_NONBLOCKING=0 giving up on claude.ai connectors after 1s instead of honoring MCP_CONNECT_TIMEOUT_MS
Fixed --channels plugin entries being checked against the installed plugin’s marketplace alone; the installed plugin’s name must now match the entry as well
Fixed --plugin-dir on a folder of plugins that also has a .claude-plugin/marketplace.json loading one empty plugin instead of the plugins in it
Fixed claude plugin uninstall refusing to remove a project-scope plugin that isn’t enabled, saying it is “enabled at project scope” while claude plugin disable says it is already disabled
Fixed claude plugin update failing for project-scoped plugins when --scope is omitted — it now resolves the scope the plugin is installed at instead of assuming user
Fixed claude plugin validate reporting privacyPolicyUrl, supportUrl and other listing metadata keys in plugin.json as unknown fields
Fixed known_marketplaces.json recording a marketplace as refreshed when its remote could not be reached and CLAUDE_CODE_PLUGIN_KEEP_MARKETPLACE_ON_FAILURE kept the existing clone
Fixed the /plugin Errors tab showing no confirmation after its last error is resolved
Fixed /plugin starting a second uninstall or update of the same plugin when Enter was pressed again while the first was still running
Fixed a y held while /plugin checks a marketplace source adding the marketplace the instant the “Add marketplace?” question appears, before it can be read
Fixed 1 answering Yes in /permissions’ delete and remove-directory confirms while the pointer is on No, which let a held 1 remove one workspace directory after another
Fixed Alt+T and /config offering to turn thinking off on models that can’t; thinking now stays on there, with a one-line reason in place of the switch
Fixed /context total leaving out messages added since the last response; it now matches its categories and can read higher than the status line
Fixed /model showing the raw API error JSON and request ID when the API refuses the picked model; it now shows the server’s message and says the model was not changed
Fixed API errors from an HTML error page (such as a proxy’s 429 or 502 page) printing the page’s raw markup or leaving out the HTTP status, and error messages breaking onto a second line when the server’s error text ended in a newline
Fixed /feedback, /bug and /share still sending your report after you cancelled it while it was being sent
Fixed /feedback, /bug and /share failing every send with “Couldn’t send feedback” after a Remote Control Stop arrived while the dialog was open
Fixed /ide showing “No available IDEs detected” while also listing a running IDE
Fixed the terminal being left in a broken state (crash or garbled input) when /setup-bedrock or /setup-vertex restarts Claude Code to apply new settings
Fixed /config exiting when respectGitignore or copyFullResponse in ~/.claude.json holds null
Fixed the session name from /rename disappearing while Claude asks a multiple-choice question, so side-by-side sessions stay identifiable
Fixed one-line pastes showing on their own lines in the sent message for prompts from VS Code or Remote Control and for expanded paste placeholders
Fixed a message queued while Claude is working losing or changing the IDE selection it was written with, and queued messages not showing their selection
Fixed pressing Shift+Tab twice quickly landing on the wrong permission mode
Fixed Ctrl+C or Ctrl+D pressed twice quitting Claude Code instead of closing the dialog in the remaining dialogs and pickers, such as /memory, /hooks, /mcp (including a server’s sign-in screen), /export, /copy, /theme, and /teleport’s uncommitted-changes and login prompts (where Esc also quit)
Fixed keys that arrive in one burst of input (e.g. over Remote Control), such as an arrow key followed by Enter, x or s, acting on the previous selection: a stale effort level in /effort and the model picker, and the previously highlighted row in /skills, the background task rows under the prompt, MCP server prompts and /install-github-app
Fixed /install-github-app updating the workflow after “Skip workflow update” was chosen, running setup twice on a repeated Enter, and ↑ on the repository step blocking a typed repository name when no repository was detected
Fixed vim mode: dj/dk/dG/dgg and their c/y forms acting on part of a line; 1G going to the last line; d0/c0/y0 doing nothing; the cursor being off by one after . repeats an insert; and o/p on a !-prefixed line switching to shell mode
Fixed vim mode cw on a space, an empty line, a word’s last letter or a one-letter word also changing the next word; word motions stopping inside words in Hindi, Bengali and other scripts; and ., p or P that inserts text starting with ! switching to shell mode, losing text or editing the wrong character
Fixed the prompt cursor moving one character too far after an accent typed as its own key
Fixed an extra blank line above a list item whose text starts on the line after its bullet, in screen-reader mode, quoted lists and long lists
Fixed bulleted lists of plain numbers (like - 316.) showing as letters, roman numerals or the wrong numbers
Fixed the agent panel’s footer hint ignoring keys rebound in keybindings.json, and showing a stray · when the stop-all-agents shortcut is unbound
Fixed the agent panel footer offering “Enter to view” and “x to stop” on the agent you are already viewing (where x types into its input), and “Enter to view” on the main row when main is already shown
Fixed a mouse click on an agent-panel row leaving the keyboard cursor on the previously selected row
Fixed Esc interrupting the running turn instead of deselecting the selected agent-panel row
Fixed PgUp and PgDn doing nothing in a dialog’s list (for example /skills) in fullscreen mode
Fixed /heapdump summary saying most memory is native when it is in the JS heap snapshot
Fixed Bash edit-diff snapshot directories piling up in the temp folder: abandoned ones are now deleted right away and the rest when Claude Code exits
Fixed /workflows moving the pointer to a different run, and x stopping it, when a new run started while the list was open
Fixed the selected tab in tabbed dialogs (/config, /plugin, /permissions) showing no highlight while the tab bar has focus when color is off (NO_COLOR)
Fixed the mouse wheel over the /plugin Installed list scrolling the pane behind it instead of the list
Fixed the hover highlight lingering on a list row in fullscreen mode after scrolling or filtering moved it away from the mouse
Fixed long list rows, such as in the /remote-control menu, wrapping onto a second line in narrow terminals; they’re now cut with …
Fixed /hooks and /mcp detail views printing a long value over the row below it in narrow terminals
Fixed lists such as a skill’s state options in /plugin not being answerable by typing a number in screen-reader mode
Windows: Fixed Bash commands that write to $TMPDIR/… failing with “Permission denied”
Windows: Fixed a race in which Claude Code sessions updating at the same moment could delete each other’s claude.exe backup, which could leave no claude.exe behind
[VSCode] Fixed opening a Web session with no messages saving an empty local copy that could not be resumed; an error now says where to continue it
[VSCode] Fixed a claude.ai/code session opening empty or with only part of its conversation, with no error, when the server failed to return its history, part of it failed to load, or a network sign-in page answered in its place; it now shows an error and can be opened again
[VSCode] Fixed conversations in editor tabs hanging silently after the extension host restarts; the tab now tells you to reopen it from the session list
[VSCode] Fixed Claude attaching option previews to multiple-choice questions in the chat panel, where the question card never shows them
[VSCode] Fixed the session manager’s cost and usage block wrapping mid-text on a narrow side bar, and showing totals from a previous login after an account switch
[Claude Code on the web] Fixed routines with a GitHub trigger for a pull request being converted to draft never firing; they now start a run when the pull request is converted
[Claude Code on the web] Fixed cloud sessions on a repository that isn’t hosted on GitHub showing a Create PR button that could never work; the button is now hidden there
[Claude Code on the web] Fixed the GitHub setup tip on claude.ai/code covering the repository picker’s search box and rows while the picker is open; it now steps aside until the picker closes
[Claude Tag] Fixed Slack channels where Claude could permanently stop responding to replies inside threads; affected channels now recover on their own with the next new message to Claude
[Claude Tag] Fixed Claude resuming a stopped request after you press Stop in Slack, for example when a check-in fired or a background task ended; messages sent mid-response are now read
[Claude Tag] Fixed Slack replies arriving many minutes late, or never, after Claude’s session crashed mid-task, such as on a failed setup script; it now restarts on its own within minutes
[Claude Tag] Fixed Claude in Slack promising an automatic restart, then failing generically, when a session’s configuration is too large to start; the thread now says why and how to retry
[Claude Tag] Fixed very long Slack threads: Claude could silently withhold a reply after judging it against weeks-old messages, and a restart deep into the thread could lose recent context
[Claude Tag] Fixed Claude answering every mention with “Couldn’t check this channel just now” in a Slack channel moved from Enterprise Grid org-wide sharing into a single workspace
[Claude Tag] Fixed very large Enterprise Grid workspaces reached mostly through channels shared across workspaces getting “Couldn’t check this channel” again after a quiet hour
[Claude Tag] Fixed a Slack request blocked by your organization’s inference hook showing a generic retry notice; the thread now shows the hook’s deny message and Claude doesn’t retry
[Claude Tag] Fixed Claude in Slack offering to switch to models your organization can’t use; it now lists and offers only models the switch will actually accept
[Claude Tag] Fixed requests to DynamoDB and Kinesis account-based endpoints failing to authenticate when sent through an AWS connection in Claude Tag
[Claude Tag] Fixed the Plugins sections in Claude Tag admin settings failing to load for organization admins and listing attached plugins as raw IDs; they now load and show each plugin’s name
[Code Review] Fixed a pull request getting no review when its reviewed commit was force-pushed away while a failed review was being retried in a repository not set to review every push

2.1.280

Mon, 21 Sep 2026 16:00:00 GMT

Added

Added Claude Opus 5.5 (claude-opus-5-5), now the default Opus model — 1M context, $4/$20 per Mtok with $0.20/Mtok cache reads
Added mouse support to more lists in fullscreen mode: the wheel scrolls the /skills list, and a skill’s state options in /plugin can be clicked
Added CLAUDE_CODE_MAX_MCP_DESCRIPTION_LENGTH to change the 2,048-character cap on MCP tool descriptions and server instructions for every MCP server in the session
Added hook output sizes and the number of oversized outputs saved to a file to the hook_execution_complete OpenTelemetry event
[VSCode] Added a Status dialog, with a typed /status, showing the session’s version, account, model and server details
[VSCode] Added a Sandbox dialog for the sandbox mode, the unsandboxed fallback and excluded commands, opened from the panel menu or by typing /sandbox
[VSCode] Added a Claude in Chrome dialog (extension status, the install, reconnect and permissions pages, the enabled-by-default setting), opened from the panel menu or by typing /chrome
[VSCode] Added Export conversation, with a typed /export, to copy or save the conversation as plain text
[VSCode] Added each skill’s source, token estimate and on/off state to the Slash commands dialog, with a click to change the state, and a typed /skills that opens it
[VSCode] Added a typed /plan that switches to plan mode, sends a first planning prompt, or shows the session’s plan
[Claude Tag] Added Slack’s native Working indicator, Stop button and thread title to Claude’s threads in channels; the indicator stays up until Claude finishes, and Stop interrupts the task
[Claude Tag] Added a short notice in the Slack channel when a guest joining, or the last guest leaving, changes how Claude responds there under a Restrict or Channel only guest setting

Changed

Reverted ctrl+l / cmd+k in fullscreen mode clearing the transcript view (added in 2.1.260); they redraw the screen again
Changed the default model on Pro and Team Standard plans from Sonnet to Opus, matching Max, Team Premium, and Enterprise
Changed an effort level saved before /effort became per-model to no longer apply to newly released models such as Opus 5.5; they start at their default until you pick a level
Changed Opus 4.7, Opus 4.8 and Fable 5 to stop holding their launch-default effort over /effort in -p or the Agent SDK, a project, managed or --settings effortLevel, or a per-model level
Changed /autocompact’s footer hint to name ←/→, the keys that adjust other ordered values
Changed /fast’s footer to name Space as the toggle key
Self-hosted runner: Changed git in lifecycle hooks to ignore hook folders and programs named in the runner’s shared git files; local-path and git:// remotes there now need GIT_ALLOW_PROTOCOL
Changed plugin marketplaces whose name imitates a reserved marketplace name to be refused when added, and to stop loading if one was already added
Changed PermissionRequest hooks: an agent-type hook no longer runs there, since its answer could never allow or deny the request; it now shows an error pointing to command or http hooks
[VSCode] Changed “Open in New Tab” to open Claude beside the editor group you are working in rather than after the last group
[Claude Code on the web] Changed the admin Routines on/off setting to live under Admin settings → Capabilities → Remote sessions; the Claude Code admin page now links to it
[Claude Code on the web] Removed the empty repository picker shown when starting a session on a self-hosted environment in an organization where an admin has turned GitHub off

Show 21 improvements

Improved /permissions: focus returns to the rule list after viewing, adding or deleting a rule, and the delete-rule and remove-directory confirmations now default to No
Improved /permissions tab navigation: ←/→ and Tab pressed in a rule list now switch tabs without moving focus to the tab bar
Improved /cost cache-miss causes to name thinking mode and thinking display changes
Improved the Artifact tool so that when Claude cannot read an artifact link it was given, it tells the user before continuing
Improved /install-github-app: the GitHub CLI check and repository selection steps now show “Esc to cancel”
Improved the /artifacts and /workflows lists: a scrollbar at the right edge shows how much of a long list is hidden and where you are in it
Improved the workflow progress tree: running agents and phases now show a dim dot instead of ⟳
Improved /plugin’s Add Marketplace form in fullscreen: it no longer draws a box inside the pane, and its text and key hints line up with the rest of /plugin
Improved the /workflows detail view in fullscreen: it no longer draws a second horizontal rule under the pane’s divider
Improved code blocks that don’t name a language: they are now colored like inline code, so commands stand out from the surrounding text
Improved /btw asked while a tool is still running: the side question now knows that call is in progress instead of reading it as a failed one
Improved the UserPromptSubmit hook timeout notice and the debug log to name which hook command timed out
Improved @ file suggestions: a file whose name contains the query now ranks above one that only matches across its folder names
Improved artifact pages: no Print buttons, confirm dialogs or device features the viewer blocks, email and phone details shown as text, and dark mode that reaches form controls and scrollbars
Improved /ultrareview uploads: renamed copies of key files, such as id_rsa copy or kubeconfig (1).yaml, now also stay on your machine
Improved the cross-session messaging startup warning to explain that --debug-file writes a debug log to a path you choose
[VSCode] Improved pasted-text handling in the chat box: a paste over 800 characters or over 2 line breaks is now marked so Claude can tell it from what you typed
[VSCode] Improved prompt handling in the chat box: invisible Unicode formatting and tag characters are removed from pasted text with a notice, and from anything else before it is sent
[Claude Code on the web] Improved cloud sessions viewed in the Claude app: Claude now saves files meant for you where the app can open them
[Claude Tag] Improved the GitHub banner in Claude Tag admin settings to say why GitHub isn’t connected: not signed in, app not linked or not installed, sign-in expired, or SSO not authorized
[Code Review] Improved the Code Review check run to say when REVIEW.md instructions were cut or left out of a review for exceeding a size limit, naming the file and the limit

Show 69 bug fixes

Fixed writes through a symlinked path being judged by their in-tree spelling: the prompt names where the write lands, and acceptEdits, allow rules and auto mode no longer approve one landing outside
Fixed auto mode retrying an action over and over when a safety check declined to review it; the action is now denied once, noting that retrying won’t help
Fixed auto mode denying actions over and over without pause when a safety check gave no answer; retries now back off, and the turn stops with a message after ten in a row
Fixed Write calls failing validation when a model sends path, file_text, file_content or a stray description instead of file_path and content
Fixed Ctrl+C or Ctrl+D pressed twice in most dialogs (/model, /effort, /config, /status, /usage, /plugin, /sandbox, /permissions, /artifacts, /mobile, /login, /upgrade, /usage-credits, /install-github-app, /setup-bedrock, /setup-vertex) quitting Claude Code instead of closing the dialog
Fixed a click that only brought the terminal window to the front also triggering the item under the pointer — in search pickers, tab bars, agent/workflow rows, slash-command links and suggestion dropdowns
Fixed a stray n closing dialogs and a stray y confirming them; Enter and Esc accept and cancel (bind y/n to confirm:yes/confirm:no in keybindings.json to restore)
Fixed text fields in dialogs losing a typed letter, digit or Space to a keybinding on that key
Fixed the prompt line staying scrambled on Windows terminals after invisible characters were removed on Enter; the screen is now repainted so you review the exact text that will be sent
Fixed the invisible-character cleanup removing the zero-width non-joiner that Persian and Arabic text uses to attach a suffix to a Latin word or number, such as the plural of “PDF”
Fixed voice dictation not stopping on Ctrl+C (the prompt cleared but the microphone kept recording), Esc not cancelling while a transcript was processing, and held Space starting dictation from the transcript view and vim NORMAL mode
Fixed a model switch made from a host app (Claude Desktop, VS Code, SDK) while Claude is working causing a prompt-cache miss on the next prompt
Fixed resumed fork subagents rebuilding their tool list instead of re-sending the one they first used, which broke prompt caching for that agent
Fixed subagent hand-back messages showing an internal provenance preamble when expanded outside verbose mode
Fixed installed_plugins.json keeping the install-time commit after updating a plugin from a GitHub repository or git URL that tracks a branch or tag
Fixed skills in ~/.claude/skills/ being moved to ~/.claude/skills/.trash/ when a manifest.json in that folder listed their names
Fixed the session feedback survey showing no hover highlight on light and ANSI themes
Fixed /workflows briefly showing a one-row list before opening the only run
Fixed the mouse wheel not scrolling selection lists with hidden options (such as /model and /permissions) in fullscreen mode
Fixed a skill you switched off showing the same red ✘ as a plugin that failed to load in /plugin and /skills; off now shows a dim ◯
Fixed multi-select option descriptions being indented under the option number instead of under the label
Fixed the search box in /plugin, /skills and /mcp losing its right border in fullscreen mode
Fixed /mcp showing △ in the server list but ⚠ in the detail view for the same server; the list, detail views and /plugin now all show ⚠
Fixed Home and End doing nothing in the /config settings list and in selection lists such as /model, /memory and permission prompts
Fixed PgUp/PgDn in the /skills menu wrapping past the first or last skill instead of stopping there
Fixed Tab silently changing the selected setting’s value in the /config list; it now does nothing there
Fixed conversations failing on every turn with a “role ‘system’ must precede an ‘assistant’ message” API error
Fixed conversations with the advisor on failing every turn with API Error 400 “Input tag ‘advisor_20260301’” behind a proxy or gateway that doesn’t support it; the request now retries without it
Fixed a session failing on every turn and /compact when its saved history held a malformed notice about MCP tools that could not be loaded
Fixed a crash when resuming a session whose saved transcript holds a malformed system message or a memory-saved notice without its file list
Fixed one cause of long-running fullscreen sessions exiting with “Claude Code exited after an unrecoverable interface error”: a damaged cached message list is now rebuilt
Fixed Claude Code hanging when a settings file, or a file it re-reads after an edit, is replaced by a named pipe mid-read
Fixed /config crashing and some on/off preferences being misread when a preference that has moved to settings.json still holds a value like null or "false" in ~/.claude.json
Fixed resuming a session with unfinished background agents, shells or workflows starting a model turn on its own before you typed anything
Fixed messages sent to a background subagent being silently lost in headless and SDK sessions when the subagent was finishing its turn
Fixed a finished subagent’s report being lost when the conversation that launched it was compacted before the report was read
Fixed background subagents being unable to use the LSP tool when an LSP plugin is active
Fixed background shell tasks reporting benign non-zero exits (e.g. grep with no matches) as failures
Fixed background sessions (claude --bg) being unable to run git, hooks, plugins and other helper programs when an environment variable handed to the session contained a NUL character
Fixed Ctrl+C needing three or four presses to exit while background subagents are running; two presses now exit
Fixed IDE selection being dropped when a sent prompt comes back into the input, such as pressing Esc to edit it, rewinding to it, or pressing Esc while startup hooks run
Fixed a ! shell-mode prompt stashed with Ctrl+S coming back as a plain prompt when restored, and / listing file paths right after stashing one
Fixed claude agents showing a blank, unresponsive screen instead of an error when the temp directory is full, not writable or owned by another user
Fixed an MCP server re-added under the same name after claude mcp remove still showing as needing authentication instead of reconnecting
Fixed background plugin marketplace auto-update ignoring git credential helpers, so private-repo marketplaces were re-cloned every run or never updated
Fixed claude plugin update clearing a plugin’s recorded commit and moving it to version “unknown” when the official marketplace’s snapshot file is a link or too large
Fixed the Artifact tool silently disappearing when your organization’s policy can’t be loaded (for example behind a web proxy); Claude now says what’s blocking it
Fixed artifact republishes silently resetting stored database access rules or dropping the viewer profile scope when that capability was re-sent without them; they are now refused
Fixed /ultrareview reporting a stopped cloud review as completed or as an error to retry, and waiting out the full timeout when its session was deleted or the signed-in account changed
Fixed the Claude app showing a missing or stale context usage figure for Remote Control and cloud sessions right after /compact or /clear
Fixed the Claude app’s diff view for Remote Control and cloud sessions dropping a branch’s committed files whenever there are also uncommitted changes
Fixed cloud and self-hosted runner sessions failing with “Authentication failed” after waiting out a long overload during which the session’s access token was rotated
Fixed memory write conflicts in Cowork sessions showing Claude only the start and end of a memory file over about 10,800 characters, so the retried write dropped the middle
Self-hosted runner: Fixed lifecycle-hook commits failing to sign under --configure-git
Windows: Fixed background cleanup deleting a directory symlink or junction used to relocate ~/.claude/session-env, image-cache or another cleaned-up folder
Self-hosted runner: Fixed a turn that ended right at a --retire-at release losing its finished signal; the runner now briefly waits for the turn to be reported before stopping the session
[VSCode] Fixed the effort chip showing a stale saved effort level instead of the level the session runs at
[VSCode] Fixed Claude Code never starting when the Python extension hangs while activating; it now starts after 60 seconds without the Python environment
[VSCode] Fixed the plan approval card never offering auto mode: when auto mode is available, its first option is now “Yes, and use auto mode”, as in the terminal
[VSCode] Fixed arrow-key navigation in the session list stopping after archiving or unarchiving a session from the keyboard
[VSCode] Fixed paste marker lines showing in your own messages after reopening a session
[Claude Code on the web] Fixed gh and GitHub API calls inside a cloud session on a GitHub Enterprise Server repository failing after about eight hours; the token now renews automatically
[Claude Code on the web] Fixed a routine that resumes an existing session running with its old prompt and name when it was edited moments before the scheduled run started
[Claude Code on the web] Fixed file links in a cloud session transcript that point outside the session’s working directory opening a file card that never loads; they’re now disabled and say why
[Claude Code on the web] Fixed auto mode refusing to retry a tool call because an approval prompt that expired unanswered, or was superseded by a newer message, had been recorded as your rejection
[Claude Tag] Fixed scheduled routines silently failing to run in Slack workspaces that were connected to Claude before the workspace joined its Enterprise Grid
[Claude Tag] Fixed Claude asking you to re-upload a Slack file when a brief file-scanning outage, not the file, was the problem; it now retries the scan and is told when the scanner is down
[Claude Tag] Fixed a bullet in Claude’s Slack reply whose text starts with +, - or * rendering as an empty bullet with a stray nested item; it now shows as one bullet with the character kept
[Claude Tag] Fixed the Slack notice for a failed cloud environment setup script sometimes being a generic “mention me to retry”; it now names the setup script and says to fix it first
