what changed.

- 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 `${` substitutions
- Fixed `Read` deny rules not applying to files @-mentioned, changed, or selected in the IDE through a symlink
- [VSCode] Reverted a 2.1.288 change to `claude auth status` that may have made sign-outs more frequent
- Improved how quickly large files open in a plugin code pane by laying the highlighted view out once at its final width
- Fixed `plugin list`, `plugin eval` and `plugin update` showing a stale copy of a plugin installed from a local folder marketplace, and hot reload for a symlinked `--plugin-dir`
- Fixed installed mods not loading in the first session after an upgrade
- Fixed a plugin's rows above the prompt showing a stale row while the Background tasks dialog was open in fullscreen
- Fixed plugin panes drawing nothing when a link used a localhost address, an `@` in its path, an uppercase host or a `file:` path
- Fixed a user-installed plugin being able to rewrite the descriptions of an organization-managed MCP server's sign-in tools
- Fixed a freeze or forced quit at launch when a plugin drew a Box with a border style the terminal does not know
- Fixed supervised and background sessions ending when a plugin's on-screen handler threw asynchronously
- Fixed sessions ending with an interface error when a plugin region with no height kept growing
- Fixed Bash deny and ask rules missing a command behind an environment variable prefix with an expanded value (e.g. `TZ="$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
- Added `agent.spawn` for teammates, one agent id across plugin hook events, and idle and waiting states in `$.agent.list()`
- 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
- 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
- Fixed published artifact pages freezing or crashing the reader's browser tab on short code blocks with many unclosed `<script>` tags
- Fixed a mod's Client region staying failed for the whole session after the terminal threw while drawing it

- 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
- 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 session titles, memory recall and prompt hooks failing on Mantle or behind gateways that reject structured outputs; added `CLAUDE_CODE_DISABLE_STRUCTURED_OUTPUTS` to turn structured outputs off
- Fixed auto mode denials pointing Claude at a Bash permission rule when the blocked tool was not Bash
- Fixed auto mode on Bedrock and Mantle switching to the local classifier for the rest of the session after a request to an older model, such as a WebFetch summary or a `sonnet` subagent
- Fixed cloud sessions that restarted on a newly picked model replying with that model after the server refused it
- Fixed Cowork cloud sessions staying marked as waiting for input after a WebFetch permission prompt for an unapproved URL went unanswered for five minutes
- Fixed prompt suggestions not appearing on a phone that joins a Cowork cloud session started on another device
- Fixed a mod's button sometimes running a different button's action when pressed on a view drawn before Claude Code restarted
- Fixed a plugin's pane showing nothing when one `Code` element held a diff that does not parse; it now draws as plain code
- Fixed plugin LSP servers receiving literal `${user_config.*}` and `${CLAUDE_PLUGIN_ROOT}` placeholders in `initializationOptions` and `settings` instead of substituted values or manifest defaults
- Fixed a plugin's `tool.call` hook making Bash fail and file searches read the wrong folder in subagents that run in a worktree
- Fixed `git-subdir` plugin installs failing, or caching an incomplete plugin, on older git (before 2.39, e.g. Ubuntu 22.04's 2.34)
- Fixed plugins loaded with `--plugin-dir` not showing "Configure options" in `/plugin`
- Fixed background sessions ending when a plugin was reloaded or disabled while one of its timers or reads was still running
- Fixed sandboxed heredocs with an unquoted delimiter (`python3 <<EOF`) asking for approval on every run under sandbox auto-allow when the body holds only plain text and simple `$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
- 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
- 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
- [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/

these notes continue in the original release.

- 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
- 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 hooks configured with `asyncRewake` waking Claude over and over with "found issues" notifications when the hook's script file is missing; the broken hook is now reported once
- Fixed tool heartbeats not reaching SDK hosts while the model's response stream was stalled with no data arriving
- Fixed Bedrock and Vertex startup model checks ignoring an enforced `availableModels` list, which could collapse `/model` to one Opus row
- Fixed the Claude in Chrome browser picker showing a JSON parse error when Chrome could not be reached
- Fixed picking Fable in `/model` on a claude.ai login saving the current version's id, so your saved default now follows the newest Fable like Opus and Sonnet do
- 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 dangerous `rm` (such as one on `/` or the home directory) losing its always-ask safeguard when the same command also redirected output to a `~` or wildcard path
- Fixed `claude -p` and SDK sessions repeating a model fallback on every later message after the model was switched while a reply was running
- 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 the commit attribution reminder being delivered inside a tool result after a compaction
- Fixed screen reader mode leaving the cursor away from the typed text in search boxes (such as /resume and /permissions) and sign-in code fields
- 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
- 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
- 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 

these notes continue in the original release.

- 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
- 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
- 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
- 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
- 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] 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
- [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
- [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
- [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] 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
- [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
- [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

these notes continue in the original release.

- 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
- 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 `&nbsp;` 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
- 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 tok

these notes continue in the original release.

- 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
- 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
- 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
- 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

these notes continue in the original release.

- 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
- 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
- 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
- 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
- [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 a

these notes continue in the original release.

- 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
- 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
- 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
- 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
- [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] 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
- [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
- [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
- [Claude Tag] Fixed auto-join channel patterns saved for one workspace in Claude Tag ad

these notes continue in the original release.

- 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
- 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 o

these notes continue in the original release.

- 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
- 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
- Reverted `ctrl+l` / `cmd+k` in fullscreen mode clearing the transcript view (added in 2.1.260); they redraw the screen again
- 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
- 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: Chang

these notes continue in the original release.

- Changed auto mode for Claude API and Enterprise users, and on Bedrock, Vertex, Foundry and gateways, to default to the server-side classifier, which does not charge for classifier overhead (`CLAUDE_CODE_AUTO_MODE_SERVER=0` opts out on Bedrock, Vertex, Foundry and gateways); warns on billed fallback. See https://code.claude.com/docs/en/auto-mode-classifier-billing
- Added an `Auto mode server` row to `/status` showing whether this session's auto mode classifier runs on the server

- Added AGENTS.md support: in a project with no CLAUDE.md, Claude Code reads AGENTS.md instead; change it under "Project instructions" in `/config`
- Added `CLAUDE_GATEWAY_PROXY_IS_EGRESS_BOUNDARY=1` for Claude apps gateways whose only egress is a forward proxy: every outbound request hands the proxy the hostname instead of resolving it locally
- Added an optional `headers:` map on Claude apps gateway upstreams, to send static headers to a proxy you run in front of a provider
- Added a line saying a background task's update is waiting when it finishes while a panel such as `/tasks` is open
- Fixed `claude -p` and Agent SDK sessions that could hang with no result after an internal error; they now report the error and exit with code 1
- Fixed conversations failing every request with "text content blocks must be non-empty" when an earlier assistant turn held an empty text block beside other content, including after `--resume`
- Fixed being unexpectedly logged out when an older Claude Code build (for example an IDE extension's bundled CLI) runs on the same machine as the current one
- Fixed interactive start-up hanging or showing an error for `ANTHROPIC_API_KEY` users when `~/.claude.json` holds a malformed `customApiKeyResponses` value
- Fixed update checks erroring every 30 minutes, and `claude update` hanging when a minimum or maximum version is set, if a proxy returns an invalid version; a malformed `minimumVersion` is now ignored
- Fixed `claude update` on winget- or apk-managed installs reporting "up to date" when the version lookup failed
- Fixed `claude plugin install` sometimes failing and breaking the installed copy when reinstalling a plugin version that a session or another program was using; an unchanged copy is now left alone
- Fixed Grep and Glob reporting no matches when the search could not start because the system was out of processes, memory or file handles; they now return an error saying so
- Fixed the Write tool silently ending the turn as a declined permission when the target path is an existing directory; it now reports a clear error
- Fixed the Edit tool treating an escaped backslash followed by `uXXXX` text as a `\uXXXX` escape, which could make an edit of a non-ASCII character rewrite an escaped backslash sequence instead
- Fixed the Edit tool reporting "Invalid regular expression: regular expression too large" instead of "String not found in file" when a very large edit containing non-ASCII text did not match the file
- Fixed a turn ending early with "Path contains null bytes" when a tool call's file path contained `\u0000` written as an escape sequence; escaped control characters now stay as literal text
- Fixed background sessions (`claude --bg`) exiting when a plugin's LSP server exited or closed its stdin
- Fixed a crash ("Type error") when opening `/mcp` or `/plugin manage` with a malformed `claudeAiMcpEverConnected` value in `~/.claude.json`
- Fixed a crash at launch when `~/.claude.json` holds a malformed `theme` value
- Fixed a crash ("unrecoverable interface error") when the prompt held text containing terminal color codes, for example a prompt recalled from history or text loaded from the external editor
- Fixed a crash when resuming a session whose saved history holds an assistant message stored as a plain string
- Fixed sessions on slow or heavily loaded machines sometimes exiting with "Claude Code exited after an unrecoverable interface error" when the first spinner appeared
- Fixed a rare case where the screen could stop updating for the rest of the session after an internal rendering error
- Fixed a rare case on Windows where a turn could stop with an error such as "Out of memory" right after Claude replied, so that reply's tool calls never ran
- Fixed sessions continued after `/clear` (restart, `--continue`, `--resume`) missing part of their first message when a SessionStart hook printed output, causing a full prompt-cache miss
- Fixed messages from other agents (such as a subagent's SendMessage) that arrived mid-turn showing up below the "Ran N shell commands" row instead of where they arrived
- Fixed the "copied" notice not appearing after drag-selecting text in the fullscreen `/resume` picker and other panels that cover the prompt area
- Fixed `$TMPDIR` expanding empty in Bash commands that run outside the sandbox while sandboxing is enabled
- Fixed WebFetch and WebSearch in Cowork cloud sessions not telling Claude why a request was refused, such as a used-up fetch budget or an admin policy
- Fixed the Claude apps gateway's telemetry relay ignoring a collector hostname or domain listed in `NO_PROXY` when a proxy is set
- Fixed one malformed `strictKnownMarketplaces` or `blockedMarketplaces` entry silently disabling the whole enterprise marketplace policy
- Fixed failed auto-updates leaving large staged downloads behind in `~/.cache/claude/staging`
- Fixed `/plugin` not stripping terminal control characters from messages on the Installed tab, such as the error of a failed plugin update
- Fixed `/plugin` → Installed and `/skills` crashing when a skill or legacy command is named like a built-in Object property such as `constructor` or `toString`
- Fixed `/plugin` closing with no message when every install in a multi-select failed
- Fixed uninstalled plugins reappearing as "failed to load" rows in `/plugin` Installed, and Remove not clearing such a row
- Fixed plugins from the official marketplace being recorded without their commit in `installed_plugins.json`, and `installed_plugins.json` keeping the old commit after updating a pinned-commit plugin
- Fixed plugin reload previews keeping every previewed copy of a plugin archive unpacked until exit, and overwriting the cached `--plugin-url` archive a reload falls back to when its download fails
- Fixed Remote Control session bookkeeping failing when `~/.claude.json` holds a malformed placeholder record
- Fixed the error after a revoked claude.ai login blaming an expired Anthropic profile; it now leads with `/login`
- Fixed typed or pasted text occasionally coming out scrambled in the `claude agents` dispatch input during key repeat or very fast input
- Fixed a crash ("unrecoverable interface error") when resuming a session whose saved transcript contains a stop hook summary without a well-formed hook list
- Fixed Enter on a selected agent panel row doing nothing when `keybindings.json` rebinds Enter in the Chat context, for example to `chat:queueSubmit`
- Fixed PDF page reads on Windows failing when the working folder's path is long (about 120 characters or more)
- Fixed a headless resume (`claude -p --resume`, the SDK, a VS Code extension window reload) starting the session's cost and usage totals at zero; headless sessions now save their totals at exit
- Fixed project skills from the main repository not loading in `--worktree` sessions when `.claude/skills` is untracked
- Fixed a `sandbox.excludedCommands` glob exempting an entire compound Bash command from the sandbox when only one part matched; every part must now match
- Fixed resumed subagents and teammates re-rendering the MCP tool definitions they had loaded, which broke prompt caching for that agent
- Fixed rate-limited artifact publishes telling Claude to stop retrying; Claude is now told nothing was published and when to send the same publish again
- Fixed attachments recorded earlier in a conversation being re-rendered after a resume or relaunch, which dropped extended thinking and missed the prompt cache
- Fixed Console sign-in showing only "Request failed with status code 400" when the server refuses to create an API key; it now shows the server's message
- Fixed messages typed while Claude is still working sometimes being ignored by the model
- Improved session start-up for SDK and headless (`-p`) use: the first turn no longer waits on the per-directory CLAUDE.md lookup
- Improved the Claude apps gateway's loopback error messages to name `CLAUDE_GATEWAY_ALLOW_LOOPBACK`
- Improved `/plugin` Installed: an MCP server listed apart from its plugin now shows which plugin it belongs to
- Improved `claude plugin install` on an already-installed plugin: it now says when the marketplace offers a newer version and names the `claude plugin update` command
- Improved the startup notice overflow line under the logo: it now reads "N more notices hidden" instead of "+N more · /status"
- Improved prompt handling: invisible Unicode formatting and tag characters in a prompt are removed and the cleaned prompt is shown for review before it is sent
- Improved `/ultrareview` when there's nothing to review: messages say which case you're in, offer a command that reviews your latest commit, and a new repository's first commit is reviewed in full
- Improved artifact link handling so Claude reads claude.ai artifact links with the Artifact tool instead of WebFetch when that tool is available
- Improved the dangerous-rm permission prompt to name the flagged rm command and suggest a `${VAR:?}` guard, so headless runs can recover
- Improved the Artifact tool's permission prompts: shorter sentences, pages and artifacts named by title or file name, and links listed after the text
- Changed Fable to always appear in `/model` on the Anthropic API; it is greyed out only when your organization's settings disable it
- Changed the Bash sandbox instructions on Bedrock, Vertex and Foundry to the first-party wording, which frames the sandbox as the boundary of what the task was given
- Changed `/ultrareview` in non-interactive sessions to refuse when the repository has no base branch or shared history
- Changed subagent results to reach the main agent under a header marking them as subagent output, with the result indented, so text in a subagent's result cannot pass as the session's own instructions
- Changed workflow scripts' computed `agent()` prompts on Bedrock, Vertex and Foundry to reach the subagent framed as script-authored text, so the safety classifier does not read them as the user
- Removed the background Haiku auto-title request from `claude -p` runs launched outside an SDK or IDE
- Removed the deprecated TaskOutput tool; Claude reads a background task's output file with Read instead, and the `taskOutputMaxChars` setting and `TASK_MAX_OUTPUT_LENGTH` no longer have any effect
- [VSCode] Added a Sign out row to the panel menu, with `/logout` in the typed command menu
- [VSCode] Added background shells and other running tasks to the agent map, each with a Stop, and a typed `/tasks` that opens it
- [VSCode] Added a Copy response button on responses and a typed `/copy`
- [VSCode] Added a one-time notice when inactive sessions are archived automatically, and an "Unarchive all" action on the Archived sessions group
- [VSCode] Added the session's cost and token usage to the Account & usage dialog and the session manager where plan limits do not apply (Vertex, Bedrock, Foundry, API key)
- [VSCode] Fixed the "General config" menu row showing `/config` usage text instead of opening settings, and made typed `/mcp`, `/hooks`, `/memory`, `/rewind` and similar commands open their dialogs
- [VSCode] Fixed the effort slider's level not persisting into later sessions on a model that already had a level saved with `/effort`
- [VSCode] Fixed Auto missing from the mode picker for conversations opened in an already-used panel when the saved model setting is a differently-cased alias such as "Sonnet"
- [VSCode] Fixed `/fast` not saving fast mode as the default, so it was lost when the extension relaunched Claude Code
- [Claude Code on the web] Added Personal and Organization sections to the environment picker on Team and Enterprise plans, and admins can now share a personal environment with the organization
- [Claude Code on the web] Changed organization environments to open as a read-only summary from the Code tab on Team and Enterprise plans, with editing under Admin settings → Cloud environments
- [Claude Code on the web] Fixed a cloud environment saved with Custom n

these notes continue in the original release.

- Fixed every request failing with `400 … Input tag 'advisor_20260301'` when `ANTHROPIC_BASE_URL` points at a proxy or gateway (2.1.275 regression)

- Added the signed-in account to Claude apps gateway sign-in: when the gateway names it, you confirm it before the credential is saved, and `/status` shows it
- Added a send-now key (ctrl+enter, or ctrl+x ctrl+s) that interrupts the current turn and sends all queued messages at once; sent and queued messages show in gray until the model receives them
- Added a startup warning when a configured `otelHeadersHelper` fails, so sessions that silently export no telemetry are noticed
- Added syncing of the skills and plugins enabled on your claude.ai account to terminal sessions signed in with it; opt out with `syncClaudeAiSkills: false` or `syncClaudeAiPlugins: false`
- Added `/plugin install <plugin> --marketplace <source>`, which offers to add the marketplace before installing the plugin
- Fixed a restored memory file's age note changing between requests after a compaction or resume, which caused prompt cache misses
- Fixed `--forward-subagent-text` stream-json and SDK output dropping the messages of subagents spawned by a `context: fork` skill, and of forked skills invoked by a subagent or another forked skill
- Fixed @-mention file suggestions being buried below MCP resources when using a custom `fileSuggestion` command or typing `@.`/`@./`
- Fixed fullscreen mode placing background-task completion notices beneath a long turn's collapsed tool row instead of where they arrived; each notice now closes the open row
- Fixed `claude plugin marketplace update` deleting a GitHub marketplace's local copy when the fetch failed and the marketplace was named after its repository
- Fixed plugin and marketplace messages, logs and `claude plugin marketplace list` showing a password or token stored in a git, ssh or marketplace URL
- Fixed a resumed cloud session leaving an unanswered question open in the transcript after a queued message superseded it
- Fixed vim mode placing the cursor one character right after a dot-repeated "!" or a fast-typed "i!" switched a non-empty prompt into shell mode
- Fixed fullscreen mode freezing or blanking for several seconds when scrolling up past a large file diff
- Fixed a stray `</ccmemory>`-style closing tag occasionally appearing in responses
- Fixed plugin messages, logs and the VS Code plugin dialog showing the wrong server for some git addresses
- Fixed a terminal `API Error: 400` on every turn for users behind a network gateway that rewrites API error responses when a beta request header is rejected
- Fixed sandboxed Bash commands on Linux reporting exit code 0 for failed commands when the shell is zsh
- Fixed the Read tool hanging instead of reporting an error when part of a large file could not be decoded under memory pressure
- Fixed `--resume`, the resume picker preview, resumed background agents and the transcript view failing on a session whose saved history contains a malformed task-reminder or @-file attachment entry
- Fixed a crash when resuming a conversation whose transcript contains a malformed message entry, and a fullscreen crash when such a conversation received new messages while scrolled up
- Fixed sessions failing to resume or start when their saved transcript contains a malformed message content block
- Fixed Grep, Glob and @-file suggestions hanging or running out of memory on searches over the 20MB output cap, and system ripgrep reporting "no matches" instead of an error after a flood of warnings
- Fixed `/rewind` in a forked or background session restoring a zero-filled or truncated file when the session's file-history backups could not be fully copied
- Fixed fullscreen sessions sometimes exiting with "Claude Code exited after an unrecoverable interface error" when typing fast or holding a key with the slash-command dropdown open
- Fixed background sessions crashing and restarting their worker when a command fed through stdin ran on a machine that had run out of file descriptors
- Fixed a crash at launch when `~/.claude.json` holds a malformed `mcpNeedsAuthNoticed` value
- Fixed `--resume` and `--continue` dropping a conversation's earlier thinking when a built-in tool it started with has since been switched off by a server-side flag
- Fixed text selected with the mouse in the fullscreen `claude --resume` session picker never reaching the clipboard
- Fixed plugin reload previews replacing a running session's extracted plugin files when the plugin was loaded from a `--plugin-dir` or `--plugin-url` archive
- Fixed self-hosted runners with `--drain-wait-sec` losing the final result of a turn that finished during a SIGTERM drain; the runner now waits briefly for the turn to be reported
- Fixed `SubagentStop` hooks with a specific `matcher` firing for every stopping subagent whose agent type was empty
- Fixed sandboxed Bash commands being unable to write to project directories named `hooks/` or `config/`
- Fixed Artifact updates failing with "File not found" after a session resumes on another machine or its scratchpad is cleared: the page's last published version is restored
- Fixed `/update-config` writing `Write(path)` permission rules, which file permission checks don't match, instead of `Edit(path)` rules
- Fixed four dead documentation URLs (Pricing, Computer Use, Skills, CLI) in the bundled claude-api skill's live-sources table
- Improved prompt caching for a `--system-prompt` that contains a `__SYSTEM_PROMPT_DYNAMIC_BOUNDARY__` line: the text above it is now cached globally, as the SDK's array form already is
- Improved the `/desktop` error when Claude Desktop does not open: it now says why and what to do next
- Improved the Artifact tool's publish and read results: they now say who can open the page and what the owner's Share menu offers
- Improved artifact publish results: they name the tab icon sent, warn when the page contains a NUL byte, and retry a flaky fetch of the newer page to merge after a stale publish
- Improved pasted and attached images: they are now saved where Claude can open them as files without a permission prompt, including in Desktop and VS Code
- Improved the Artifact tool's guidance so Claude updates a shared artifact in place when you were given edit access to it, instead of publishing a separate copy
- Improved plan-usage reads: editor windows and non-interactive sessions on one machine now share a read made in the last minute instead of each calling the usage endpoint
- Improved the `ListPlugins` tool description so Claude knows it lists plugins enabled on your claude.ai account, not plugins installed locally with `/plugin`
- Improved responsiveness when the terminal is slow or paused: output no longer falls further behind while the terminal catches up
- Improved Write and Edit results for files in the synced account-skills folder: they now say the change is not saved to your account and how to save it
- Updated `/logout` for Claude apps gateway sign-ins to also end the session on gateways that advertise token revocation
- Changed hosted sessions to keep an unanswered permission prompt up after a container restart, instead of asking again
- Changed the Artifact tool to ask for a one-word tab icon on a first publish instead of an emoji favicon
- Changed Claude in Chrome in auto mode to skip the extension's per-site check for classifier-approved calls, as bypass mode does, fixing `browser_batch` "Permission denied" after a redirect
- Changed plugins installed from an npm source to be fetched with `npm pack --ignore-scripts` and integrity-verified, so a package's install scripts no longer run
- Changed scheduled and Run now routine runs to save data to, and republish the page of, an artifact you can edit without asking; public artifacts, first publishes and deletes still ask
- Removed the startup notice that told you a one-off scheduled routine had run since your last session
- [VSCode] Added viewing, editing and deleting a saved memory inside the Memory dialog
- [VSCode] Added sending an attached image without typing any text
- [VSCode] Added a Retry link to the MCP servers dialog when the server list fails to load
- [VSCode] Added accept and reject buttons under each change in the proposed-change diff tab, so an edit can be reviewed change by change
- [VSCode] Fixed the transcript creeping toward the bottom in small steps while a permission card waits and content keeps arriving
- [VSCode] Fixed rewound and forked conversations not keeping the permission mode you had picked for the original conversation
- [VSCode] Fixed an empty `CLAUDE_CONFIG_DIR` entry in the `environmentVariables` setting making Claude Code keep its files in the workspace
- [VSCode] Fixed plugin install links opening the Manage plugins dialog for plugin names and marketplace addresses that can't be used in a link
- [VSCode] Fixed Remote Control staying shown as connected after a turn-off that Claude Code reported as failed; it now shows as off
- [VSCode] Fixed the scroll to the bottom on send stopping short of the reply when the reply starts arriving during the scroll
- [VSCode] Fixed the agent map showing agents a crash left unfinished as stopped instead of failed once the session is reopened
- [VSCode] Fixed the "Continuing the step" notice not appearing, and the continue limit resetting, after a reload that follows a crash with background tasks still running
- [VSCode] Fixed the session list showing when a session was last reopened, such as after a window reload, instead of when its last message was sent
- [VSCode] Fixed "Fork conversation from here" failing on the message right after one sent while Claude was working
- [VSCode] Fixed the prompt cache clock showing too few minutes after reopening a session with a message sent while Claude was working
- [VSCode] Fixed a background agent that finished while Claude was running a tool losing its completion notice, and its result on the agent map, after a window reload
- [VSCode] Fixed a rare case where text selected in a git-ignored file could be sent to Claude after the extension was unresponsive for several seconds
- [VSCode] Fixed renaming a running session reverting to the generated name (regression in 2.1.269)
- [VSCode] Fixed slash commands typed while Claude is responding being sent to the model as text instead of running once the response finishes
- [VSCode] Fixed unreadable code in the plan preview and the Hooks and Permission rules dialogs with the High Contrast Light theme
- [VSCode] Fixed `/remote-control` being ignored while Remote Control is still connecting: running it again now turns Remote Control off immediately
- [VSCode] Fixed the conversation pulling you back to the bottom while a reply streams after you scroll up, and added a `claudeCode.scrollToBottomOnSend` setting to turn off the jump on send
- [VSCode] Fixed the Manage plugins dialog showing a password or token that was typed into a marketplace URL
- [VSCode] Improved the agent map: the pill counts running agents and turns red after a failure, the main agent stays in view while the map scrolls, and agents sort by state then end time
- [VSCode] Changed New session in a Claude editor tab to open in the sidebar when Preferred Location is set to Sidebar, instead of always opening another tab
- [VSCode] Changed a message sent while Claude is working to wait at the bottom of the conversation until Claude starts on it
- [Claude Code on the web] Added a "New routine" button to the page shown when a routine link no longer resolves, next to the link back to your routines list
- [Claude Code on the web] Fixed routine "paused" and "on hold" notifications being cut off mid-sentence; the paused-subscription notice now says to turn the routine back on yourself
- [Claude Code on the web] Fixed cloud environments with a very long allowed-domains list saving fine and then failing every session start; saving now fails up front and says how much to trim
- [Claude Code on the web] Fixed Claude's guidance when a cloud session on a personal account is denied GitHub access: it now links to claude.ai/connect-github instead of

these notes continue in the original release.

- Added a visible warning when memory usage is critical, with steps to free memory or restart safely
- Added `CLAUDE_CODE_MCP_STARTUP_WAIT_MS` to bound how long the first non-interactive turn waits for connecting MCP servers (`0` = don't wait)
- Added `effort` attribute to the `claude_code.llm_request` OpenTelemetry trace span, matching the `api_request` event
- Added `claude_code.managed_settings_resolved` OTel event: managed-settings sources and policy helper state; redacted settings and digests with `OTEL_LOG_MANAGED_SETTINGS=1`
- Added `store.connect_timeout_seconds` to the Claude apps gateway config to lengthen the Postgres connect timeout (default 5 seconds), and improved the boot error when the database is unreachable to point to `store.postgres_url` and the configured timeout
- Added `enduser.sub`, the IdP subject, to the telemetry Claude Desktop and Cowork send through a Claude apps gateway
- Added a Claude apps gateway warning when a replica has more requests open than the 256 it sends upstream at once, and a startup log line showing that limit
- Added click-to-expand for collapsed teammate and agent messages in fullscreen mode
- Fixed sessions getting stuck endlessly retrying "unexpected tool_use_id" 400 errors: corrupted transcripts now self-heal where possible, and otherwise a clear error (with a `/rewind` hint) ends the loop
- Fixed MCP servers configured as `http` that only speak legacy HTTP+SSE failing to connect when they answer the first request with 422 or another 4xx error
- Fixed Streamable HTTP MCP tool calls timing out after about 5 minutes even when a longer per-server `timeout` was set
- Fixed MCP prompts and resources not refreshing when a server sends list-changed notifications without declaring `listChanged`
- Fixed MCP tool calls refused with 403 insufficient_scope being reported as an expired sign-in: the error now names the missing permissions and points to `/mcp` re-authentication
- Fixed hook-driven sessions (such as an active `/goal`) ending with "Prompt is too long" instead of compacting when the context overflowed again after a reactive compaction
- Fixed an active `/goal` being lost when resuming (`--continue` / `--resume`) a session that had compacted
- Fixed `claude agents` losing `--model`, `--effort`, `--permission-mode`, `--allow-dangerously-skip-permissions` and `--agent` after an auto-update relaunch
- Fixed a per-turn slowdown when a language server publishes project-wide diagnostics for thousands of files
- Fixed subagents with `model: "opus"` on Bedrock, Vertex or Foundry leaving the session's model when its id has no recognizable model family (unless `ANTHROPIC_DEFAULT_OPUS_MODEL` is set)
- Fixed self-hosted runner sessions failing every turn with a 401 after a few failed token refreshes, until the next scheduled refresh; the runner now keeps retrying, and fetches a new token after a 401
- Fixed clickable links to local file paths doing nothing in VS Code and other terminals that require a `file://` URI
- Fixed the transcript renumbering ordered lists in your own messages (typing "3. 2. 1." displayed "3. 4. 5."); numbers and "N)" markers now show as typed

- Fixed a local `claude -p --resume` started with `CLAUDE_CODE_RESUME_INTERRUPTED_TURN` not reporting background tasks the previous process left unfinished
- Fixed the first turn of a cloud session sometimes starting without the tools of an SDK-hosted MCP server that was still connecting
- Fixed background agent notifications claiming the agent had no live background work when it was still waiting on its own background task and would resume
- Fixed error hints in Claude Desktop sessions to suggest slash commands like `/usage-credits` instead of CLI flags that cannot be used there
- Fixed `/schedule` saving a routine's prompt without its message role when Claude writes the routine in the shape that listing routines returns
- Fixed `/status` not showing the `apiKeyHelper` failure that its own error banner told you to check
- Fixed `/fast on` in non-interactive sessions reporting on and then turning off under an organization's managed fast mode policy; it now says the organization has disabled it
- Fixed the Artifact tool asking you to approve an update to an artifact that it then refused because the session had not read the latest version
- Fixed Cowork and claude.ai cloud sessions with network access on treating reads of a teammate's artifact as if network access were off
- Fixed a plugin or marketplace directory with no git repository of its own taking its version from an enclosing git repository, such as a git-managed `~/.claude`
- Fixed `--strict-mcp-config` with an empty `--mcp-config` holding the first non-interactive turn for up to `MCP_TIMEOUT` on incidental MCP servers
- Fixed Stop prompt hooks re-sending their whole prompt on every block in a conversation; repeat blocks now name the condition with a 500-character label
- Fixed extra empty editor windows opening at startup on Linux under Wayland when running inside the Cursor or VS Code terminal
- Fixed an unhandled promise rejection in the Claude apps gateway when Postgres drops a connection during a spend check
- Fixed Claude apps gateway cutting every open stream on SIGTERM: it now lets in-flight requests finish for up to 25 seconds before exiting (`CLAUDE_GATEWAY_DRAIN_TIMEOUT_MS`)
- Fixed `installed_plugins.json` being rewritten on nearly every start-up when plugin policy comes from remote managed settings, which made Claude Desktop reload every open session's plugins
- Fixed headless and SDK sessions making a separate model call for every background task that finished; completions already queued are now answered by one call
- Fixed the Bash tool re-sourcing the shell profile (a multi-second stall on the next command) after every plugin reload; it now does so only when the plugins' `bin/` directories changed
- Fixed plugins with a top-level `$schema` in `hooks/hooks.json` showing an "unknown key" notice
- Fixed MCP connection errors and the MCP login tool's description showing secrets resolved from `${VAR}` placeholders in MCP configs
- Fixed Bash permission checks for commands that loop over or assign certain special shell variables; these commands now ask for permission
- Fixed worktree-isolated sessions accepting Bash commands with certain nested shell expansions; these are now refused
- Fixed the Edit permission prompt preview sometimes showing a different location than the approved edit in files with multi-byte characters
- Fixed background commands being stopped after 30 idle minutes on machines under mild memory pressure; they're now stopped only when memory is critically low, and the debug log says why
- Fixed a message a subagent sends to the main session disappearing from the Claude Desktop transcript after a relaunch
- Fixed a plugin loaded from a `.zip` being served from a stale extraction after several overlapping reloads
- Fixed a sub-agent's progress summary being replaced by a runaway multi-paragraph reply
- Improved startup in `--input-format stream-json` sessions: the first turn no longer waits up to 2s for still-connecting MCP servers whose tools tool search defers; they arrive on a later turn
- Improved Monitor tool notifications: a script's final output and its exit now arrive as one notification instead of two, saving a model turn
- Improved Artifact tool errors: when you are not signed in to claude.ai the terminal now says so on the first attempt, and Claude is told to stop retrying a rejected call sooner
- Improved artifact publishing: a publish built on an older version is stopped before it is sent, with the newer page to merge
- Improved safety checks before removing an agent worktree that contains submodule checkouts
- Improved `OTEL_LOG_RAW_API_BODIES=file:<dir>` output: a new `index.jsonl` and `request_body_id` / `message.id` event attributes link each response to its request file and transcript message
- Improved Claude apps gateway boot: it now tries the first Postgres connection up to three times before exiting, so a database that is reachable a few seconds late no longer fails the boot
- Improved the Claude apps gateway's spend-limit check under load: it now takes one database round trip instead of four, so fewer checks time out on a busy gateway
- Improved Claude apps gateway sign-in rate limit errors: `/login` now explains the refusal, and the gateway log says which limit was hit and which setting to change
- Changed Bedrock, Vertex, Foundry and telemetry-disabled installs to use the v2 MCP client and MCP 2026-07-28 negotiation with direct HTTP servers by default, as other installs already do (opt out: `MCP_SDK_GENERATION=v1` or `MCP_PROTOCOL_NEGOTIATION=legacy`)
- Changed `/code-review` to use leaner inline review prompts for every model that has no tuned settings of its own, instead of spawning many review subagents
- Changed `"type": "sdk"` MCP entries in `.mcp.json`, settings, plugins and agent files to be skipped with a warning: only an SDK host application can register in-process servers
- Changed artifact watching in local sessions: a new version published elsewhere no longer starts a turn; Claude learns of it from a later Artifact tool result
- Changed plugin and marketplace clones to leave Git LFS files as pointers instead of downloading them; `git lfs pull` in the checkout fetches them
- Changed self-hosted runners to skip a read-only repository the git host refuses at the access check instead of failing the session start
- Changed the `/status` GitHub line to read "Cloud sessions", and `/web-setup`, `/ultrareview`, and teleport messages to say "cloud session" instead of "Claude Code on the web"
- [VSCode] Added continuation of the step a window reload interrupted, labeled in the chat, with a Claude Code: Continue After Reload setting to turn it off
- [VSCode] Added Memory and Instructions entries to the Customize menu: Memory shows the auto-memory toggles, the saved memories and the memory folders, and Instructions edits the CLAUDE.md files
- [VSCode] Added a `claudeCode.lockEditorGroups` setting to stop Claude from locking the editor groups it opens in
- [VSCode] Fixed a `/btw` side question asked in a new conversation's first seconds occasionally showing another session's side-question history
- [VSCode] Fixed a brief freeze when the extension first looks up your global gitignore file
- [VSCode] Fixed a message sent while Claude was running a tool disappearing from the conversation after a window reload
- [VSCode] Fixed the Manage Plugins enable toggle and MCP servers dialog rows being unreachable from the keyboard
- [VSCode] Fixed sign-ins and sign-outs made in a terminal not showing until a reload after `CLAUDE_CONFIG_DIR` changed in the Environment Variables setting
- [VSCode] Fixed Edit diffs in the chat being cut off at the bottom at some panel widths and for long wrapped lines; diff boxes now fit the rows shown
- [VSCode] Fixed overlapping settings writes from the extension leaving `~/.claude/settings.json` unparseable or dropping a setting
- [VSCode] Fixed Open in New Tab (Ctrl/Cmd+Shift+Esc) sometimes leaving the new tab's message box unfocused, so typing went nowhere until you clicked it
- [VSCode] Fixed reopening a closed Claude tab splitting the editor layout when its locked group still holds another Claude tab and a file
- [VSCode] Fixed New session opening another locked editor group whenever a file tab shared the group with your Claude tab
- [VSCode] Fixed session names shifting sideways in the session picker while typing a search query
- [VSCode] Fixed the plan review card cutting off its Send feedback button a

these notes continue in the original release.

- Added `x-claude-code-request-class`, `x-claude-code-agent-type`, `x-claude-code-prev-tool-durations`, `x-claude-code-compaction` and `x-claude-code-context-compacted` request headers for LLM gateways; opt in with `CLAUDE_CODE_GATEWAY_HINT_HEADERS=1`
- Added a notification when an MCP server disconnects mid-session and automatic reconnection gives up, pointing at `/mcp`
- Added forking a session started with `claude --remote-control` or `/remote-control` from the Claude app; the fork runs as a background session on your computer
- Fixed Bash commands the permission checker cannot fully analyze skipping the prompt under `permissions.blockReadsOutsideWorkingDirectories`, and a subshell hiding a dangerous `rm` in bypass mode
- Fixed skills synced from claude.ai staying available after your organization turns Skills off; they now move to the recoverable trash
- Fixed `allowManagedMcpServersOnly`, `deniedMcpServers` and `disableClaudeAiConnectors` set via MDM or `managed-settings.json` being ignored when server-managed settings are also present
- Fixed 401/403 errors on Bedrock, Vertex and Foundry, and Claude apps gateway 403s, telling you to run `/login`; the message now names the credential to refresh or points to your gateway administrator
- Fixed `/login`, `/upgrade`, and `/extra-usage` discarding earlier thinking from the conversation, which forced a full prompt-cache rewrite on the next request
- Fixed auto mode stopping for approval when the Artifact tool uploads a file you attached to the chat in a cloud or Remote Control session
- Fixed a long-running session recreating a stub `.git/info/exclude` after the repository's `.git` directory was removed or moved away
- Fixed the main prompt dropping a `!` typed at the start while already in shell mode, so negated commands like `! grep …` can be typed
- Fixed Read on macOS refusing a dragged-in screenshot, or any file the system reports under a second path, with "symlink resolution changed after permission was checked"
- Fixed `permissions.blockReadsOutsideWorkingDirectories`: a memory directory chosen by a repository's settings is no longer loaded into the prompt, recalled, indexed, or used by memory extraction
- Fixed sub-agents and background agents being reported as failed, with their result never delivered, when the final streamed reply omitted token usage or carried no model id
- Fixed the context meter and auto-compact counting advisor-tool turns at roughly twice their real context size, which made auto-compact fire at about half the real window
- Fixed `/tui` refusing to restart because of an agent-team teammate that had already finished its work and was no longer shown in the agents panel
- Fixed saved scheduled tasks running in the wrong session after `.claude/scheduled_tasks.json` was copied into another folder, such as a new worktree
- Fixed SDK and `--output-format stream-json` output dropping a subagent's remaining messages and final report after it is moved to the background mid-run (e.g. by `CLAUDE_AUTO_BACKGROUND_TASKS`)
- Fixed `/install-github-app` reporting a SAML single sign-on block as "admin permissions required"
- Fixed Remote Control clients attached to a Claude Desktop, VS Code or JetBrains session being refused when they ask for the session's context window usage
- Fixed the spinner showing a doubled ellipsis ("……") on compaction status lines such as "Running PreCompact hooks…"
- Fixed a false-positive spinner tip suggesting the frontend-design plugin after reading or publishing Artifacts
- Reverted a 2.1.268 change that checked Read and Edit deny rules on Bash lines the permission checker can't analyze (`eval`, `env -C`); commands like `time -p make build` prompt again instead of being denied
- Improved responsiveness in long sessions: hook progress and sub-agent activity no longer re-process the whole conversation on every update
- Improved the Artifact tool's error when a publish includes a file type artifacts don't serve: Claude is told which types are served and what to do instead, and the terminal shows one plain line
- Improved the Artifact tool's page read to state the capabilities and database rules the artifact service holds for the page, for anyone who can publish to it
- Improved artifact database writes: an update can now remove a single field instead of rewriting the whole document
- Improved artifact publishing: a publish whose connection drops after reaching claude.ai is now re-sent safely instead of failing or creating a duplicate version
- Improved the cloud-session GitHub error for an IP allow list, a suspended app installation or SAML single sign-on to show the cause instead of a generic install hint
- Improved `/autofix-pr`: when `gh pr view` fails it now shows gh's own error (sign-in, SAML, rate limit) instead of a generic exit-code line
- Improved `/autofix-pr` to say why GitHub webhook delivery couldn't be set up for the PR (for example, no linked GitHub account) instead of a generic warning
- Improved `/web-setup` errors: a refused GitHub token now lists the likely reasons and the fix, and a connection failure names a configured proxy or TLS certificate problem
- Improved the in-session SSL certificate and proxy connection errors to name the error code and what to fix, such as `NODE_EXTRA_CA_CERTS` for an untrusted corporate CA
- Improved the error when a cloud session can't be created because your Claude login expired or was revoked: it now tells you to run `/login`
- Improved the error shown when an MCP server's sign-in expires mid-session to say how to re-authenticate (`/mcp`)
- Changed auto mode on Bedrock, Vertex and Foundry to use the local classifier by default for now; set `CLAUDE_CODE_AUTO_MODE_SERVER=1` to use the platform's server-side classifier
- Changed `OTEL_LOG_TOOL_DETAILS=1` to also include real agent, skill, plugin and MCP server names on cost and token metrics
- Changed sign-in with a Claude account to also request access to your claude.ai plugins
- Changed `/bug` and `/feedback` reports to include only model-behavior params (model, system prompt, tools) from the last API request, omitting request metadata and `CLAUDE_CODE_EXTRA_BODY` fields
- [VSCode] Fixed "Report a problem" still appearing, and `/bug` / `/feedback` opening a report form, for organizations that have product feedback disabled
- [VSCode] Fixed a red "Claude Code process exited with code 4294967295" banner appearing after completed turns on Windows
- Windows: Improved the network-path permission check for UNC paths when a mapped network drive was added with `--add-dir`
- [Claude Code on the web] Fixed routines losing access to an organization connector, and still calling the old one, after an admin removed and re-added that connector
- [Claude Code on the web] Fixed creating a self-hosted environment from organization settings occasionally failing with a server error and leaving a half-created environment behind
- [Claude Code on the web] Changed the admin "Share cloud sessions" setting to live under Data and privacy instead of the Claude Code page, where Data and privacy admins can also manage it
- [Claude Code on the web] Added a "Discard unsaved changes?" confirmation before the New routine page or the Edit routine dialog throws away a routine name, prompt or edit you typed
- [Claude Code on the web] Removed the full-page desktop-app download screen that new users without a cloud environment saw on Mac and Windows; they now go straight to setup
- [Claude Code on the web] Improved the routine detail page: menu and rename in the breadcrumb, the on/off switch and Run now at the top, and run history beside the routine's settings
- [Claude Tag] Fixed Claude going silent minutes after reinstalling the app when an Enterprise Grid was disconnected but one of its workspaces stayed connected
- [Claude Tag] Fixed scheduled tasks set up in an organization-shared private Slack channel silently never posting; they now keep running in the thread they were created in
- [Claude Tag] Fixed replying in an older Slack thread while Claude is mid-task sometimes restarting it from scratch and losing work it had not pushed yet
- [Claude Tag] Fixed Claude occasionally dropping a message with an incorrect "couldn't find a Claude Code environment" notice right after your account token refreshed
- [Claude Tag] Fixed AWS connections refusing region-less endpoints such as Budgets, Savings Plans, WAF Classic and Import/Export; Global Accelerator requests now sign correctly
- [Claude Tag] Improved AWS connection failures: when a request can't be signed, such as a hostname with no region, Claude is told why and how to fix it instead of a bare error
- [Claude Tag] Fixed OAuth client-credentials and JWT-bearer connections failing with providers that return a lowercase token type; requests now send the standard Bearer scheme
- [Claude Tag] Fixed adding a channel manager being refused on Enterprise Grid shared channels, on channels where Claude hasn't been used yet, and on legacy private channels
- [Claude Tag] Changed Claude to start watching related public channels on its own, such as an incident channel a conversation depends on, instead of only when asked
- [Claude Tag] Fixed the admin Memory page not listing Slack channels Claude set up on its own even when they had saved memory; admins can now open, edit and delete that memory
- [Code Review] Fixed merging the base branch into a PR whose earlier review listed "Additional findings" triggering a full re-review; these pushes now get the lighter follow-up review
- [Code Review] Fixed a whole REVIEW.md being ignored because of an @-mention, a code span wrapped across lines, or a backticked HTML tag; only lines linking to changed files are withheld
- [Code Review] Improved suggested fixes to say what the fix must keep working when other code depends on the behavior being changed
- [Code Review] Improved review comments that point to a second affected location to state that location's issue in a full sentence instead of a cut-off stub
- [Code Review] Fixed `/ultrareview --post` so a retry after a GitHub error posts the findings comment exactly once instead of never or twice; the comment now names the reviewed commit
- [Code Review] Fixed empty or content-identical pushes being re-reviewed on GitHub repositories whose owner or name contains a capital letter; these pushes are now skipped

- Bug fixes and reliability improvements

- Added fast mode in Claude Code Remote sessions (cloud and self-hosted runners): the host's fast-mode setting or `/fast` typed in the session applies where your organization allows it
- Added mouse support to the `/config` panel in fullscreen mode: the wheel scrolls the settings list, a click on a setting's value changes it, and the row under the pointer is highlighted
- Added `claude self-hosted-runner --drain-marker-file <path>`: when that file exists at a SIGTERM drain, the runner reports its exit to the server as a host drain (telemetry only)
- Added per-command `allowed_domains` to Bash, PowerShell and Monitor in auto mode with sandboxing: the hosts a command needs are reviewed with it and opened for it alone; other hosts are refused
- Added `omitClaudeMd` to agent frontmatter and `--agents` JSON, letting custom and plugin subagents run without user, project and local CLAUDE.md files; managed policy files still load
- Added `--accept-command <sha256>` to `claude plugin install` and `claude plugin update` to accept exactly the command a previous `--json` run displayed, instead of `-y`
- Added support for a `multiplier` above 1, up to 10, in the `modelPricing` managed setting and the Claude apps gateway `pricing` block, for marked-up internal chargeback rates
- Added a spinner tip pointing Bedrock, Vertex AI, Foundry and LLM gateway users to the Claude desktop app; the claude.ai desktop app tip now suggests `/desktop`, which offers to download the app
- Fixed a cached organization policy being reused after switching accounts, organizations, or API keys, and the policy not refreshing until the hourly check when the credential changes mid-session
- Fixed the tool and command lists not updating when the organization policy finishes loading after startup or changes mid-session
- Fixed an enterprise `managed-mcp.json` that can't be read or parsed being ignored: it now keeps exclusive MCP control (user, project and plugin servers don't load) and warns at startup
- Fixed org policy being fetched through, and rejected by, third-party local proxies set via `ANTHROPIC_UNIX_SOCKET`; they are again treated like other custom gateways, including for Remote Control
- Fixed cloud sessions rejecting every subagent tool call ("updatedInput … failed schema validation") when a workflow or agent approval was applied after the session's worker restarted
- Fixed `/fast off` answering "Fast mode unavailable" instead of turning fast mode off when the organization has fast mode disabled
- Fixed sessions started with `CLAUDE_CODE_SKIP_FAST_MODE_ORG_CHECK` re-sending fast requests every turn after the API rejected fast mode; the rejection now stands and its reason is shown
- Fixed fast mode under `CLAUDE_CODE_RETRY_WATCHDOG` failing the turn on a usage-credits limit, or retrying an overload at fast speed, instead of falling back to standard speed
- Fixed Bash permission checks missing the file that `fmt`, `column` and similar commands read when it follows an option the checker doesn't recognize
- Fixed Bash permission checks skipping files a wildcard expands to when the wildcard sits in a command's pattern or option value (for example `grep -v dir/* file`)
- Fixed Bash permission checks so that shell variable declaration flags cannot misrepresent the command being run
- Fixed Bash commands with two directory changes, a subshell, or a `cd`+`git` chain skipping the prompt under `permissions.blockReadsOutsideWorkingDirectories` in bypass and auto mode
- Fixed a stale `.git/config.lock` breaking `git checkout -b`, `git push -u` and `git config` for the rest of a session after a sandboxed command failed to start (Linux)
- Fixed settings file changes made outside the session going unnoticed on macOS machines whose system file-event service is saturated; the watcher now falls back to polling
- Fixed resumed `claude -p` sessions whose tools all come from MCP servers failing with "At least one tool must have defer_loading=false"
- Fixed turns failing with "API returned an empty or malformed response" when an LLM gateway returns the non-streaming reply as `text/plain`
- Fixed sustained high CPU usage and repeated tool-list requests when an MCP server sends `list_changed` notifications in a tight loop
- Fixed MCP OAuth mishandling client registrations: denying consent forced a new one, one for another redirect URI was reused, and a concurrent write could delete a valid one or keep a mismatched one
- Fixed tool search returning no match when Claude selects an MCP tool by its bare name instead of its full `mcp__server__tool` name
- Fixed Ctrl+O cancelling pending MCP server reconnects, and `/mcp` sent from Remote Control failing while the transcript view is open
- Fixed the Claude in Chrome prompt telling the model to load tools through ToolSearch when ToolSearch is unavailable
- Fixed cross-session messages held by the receiving session's permission-mode policy leaving no trace: headless senders now get a delivery notice, and `SendMessage` results no longer imply it was read
- Fixed Claude starting a second copy of a background command (such as a watch task or dev server) that was still running after the conversation was compacted
- Fixed `/model` warning about losing the conversation cache when switching back to the model the conversation actually ran on
- Fixed `/reload-skills` reporting a skill count that disagreed with the slash menu after `/cd`
- Fixed `/resume` and `/continue` showing only 1-2 sessions in fullscreen mode on short terminals
- Fixed `/resume` and `/teleport` keeping the previous conversation's file-read tracking, so Claude could edit files the resumed conversation had never read
- Fixed `--resume` dropping the 1M context window (`[1m]`) when the resumed session's model family differs from the configured default model
- Fixed artifacts attached with `/artifacts` disappearing from the session after `--resume`
- Fixed background sessions (`claude --bg`, `claude agents`) not watching the artifacts they publish for republishes made elsewhere
- Fixed custom agents, slash commands and output styles beyond the first not loading from a virtual drive that reports inode 0, such as an encrypted vault mounted as a Windows drive
- Fixed self-hosted runner sessions silently losing all host config (settings, skills, plugins, MCP servers) when the host config directory exceeds 64 MiB; added `--host-config-snapshot disk|memory`
- Fixed skills synced from claude.ai staying on disk indefinitely after signing out; copies not refreshed within `cleanupPeriodDays` now move to the recoverable trash at the next launch
- Fixed spinner tips suggesting commands that aren't available for your account type or are disabled in your session
- Fixed the `/add-dir` path input: the left and right arrow keys now move the cursor, and Enter adds only the typed path instead of also adding the highlighted completion
- Fixed text fields outside the main prompt moving a leading `!` to the end of what you typed (`!foo` came out as `foo!`)
- Fixed the interactive `/hooks` menu crashing when a hook matcher is named after an inherited object property such as `__proto__` or `constructor`
- Fixed a fullscreen rendering glitch where text kept a stale background color after the box around it lost its background
- Fixed Delete in st and Alt+arrow keys in rxvt-unicode not working in attached background sessions
- Fixed the terminal's replies to capability queries (`^[[?1;2c`) appearing at the shell prompt or in an editor when Claude Code exits, is suspended, or opens an editor right after starting
- Improved terminal rendering performance: large diffs and long transcripts render faster, with fewer slow frames
- Improved startup time slightly by skipping a redundant validation of built-in model data on every launch
- Improved hook feedback: while a SessionStart, UserPromptSubmit, PreToolUse or SessionEnd hook runs, the spinner says so with elapsed time, and Esc cancels a prompt waiting on a SessionStart hook
- Improved the spinner status during long thinking: it now reads "deep in thought" after 45s, and shows "picking the thought back up" while recovering from the output-token limit
- Improved dynamic workflows to pause when you hit your usage limit and continue automatically when it resets, instead of dropping the affected agents
- Improved Remote Control to leave fewer empty sessions on claude.ai when setup fails on a flaky network
- Improved the Claude in Chrome message in cloud sessions when the browser can't be reached: it now says the computer may be asleep before it suggests an install
- Improved `claude mcp serve`: a running tool call now sends a progress update every 30 seconds, so clients show it is still running and idle timeouts don't abort a long command that prints nothing
- Improved Foundry and Claude Platform on AWS sessions: an `alwaysLoad` MCP server that finishes connecting mid-conversation is usable on the next turn without a tool-search round trip
- Improved Markdown files published as artifacts: they now render as styled document pages (title header, document typography, syntax-highlighted code)
- Improved Artifact tool publish errors: a publish with no file now says to write the page to a file first, and an unsupported file type is reported before a missing favicon
- Improved the Artifact tool's error when a page declares a capability its contract version lacks: it now lists every supported capability and notes when a newer contract version has it
- Improved artifact watching: a session can now watch up to 10 published artifacts at once for republishes made elsewhere, up from 5
- Improved PDF @-mentions to say "page count unknown" instead of a page count guessed from the file size when pdfinfo cannot count the pages
- Improved `/mobile` to show a single QR code for claude.ai/mobile, which opens the right app store for your phone
- Changed auto mode so that a skill's or slash command's inline `!` shell commands follow default-mode permission rules instead of the classifier; a command no rule decides runs as a reviewed tool call
- Changed auto mode so a subagent reports back to its caller through a dedicated hand-back call that the safety classifier reviews, instead of its last message being reviewed after the fact
- Changed Monitor watches to always have a deadline (at most 30 minutes; 10 in single-prompt `-p` runs) and notify Claude to re-arm, replacing the no-timeout `persistent` option
- Changed the IDE selection indicator in the prompt to a `[⧉ …]` pill that wraps with the text instead of squeezing multi-line prompts; delete it with Backspace to leave the selection out
- Changed the default dynamic workflow size to small on Pro plans and lowered the medium size guideline from 15 to 10 agents
- Changed Claude apps gateway, Bedrock, Vertex AI, and Foundry sessions so that they no longer refresh a leftover claude.ai login that the session does not use
- Updated the bundled `claude-api` skill to enable `eager_input_streaming` on streaming custom tools, and to start deliverable-shaped Managed Agents work with `user.define_outcome`
- [VSCode] Added an Attach Open File setting that, when turned off, stops the open file from being added to messages; selected text is still attached
- [VSCode] Fixed the Hooks and Permission rules dialogs reporting a save that landed as failed, and the Hooks dialog going blank under a plugin-only policy lock or showing color codes in save errors
- [VSCode] Fixed Hooks dialog saves: no duplicate hook on replace, a header name retyped in other capitals keeps its secret, and settings.local.json is gitignored before the save returns
- [VSCode] Fixed session history showing only the current session when the workspace is on a Windows mapped network drive or SUBST drive
- [VSCode] Fixed the session list's Active filter hiding open idle sessions when Open is also checked in the filter menu
- [VSCode] Fixed a new chat switching back to the previous chat when the session list refreshed
- [VSCode] Fi

these notes continue in the original release.

- Fixed read-only git commands in Bash unexpectedly asking for permission after a session had been running for a while (regression in 2.1.269)

- Added `claude plugin eval`: run a plugin's eval suite against Claude Code and get scored, reproducible results (JSON + HTML report); see `claude plugin eval --help`
- Added `/output-style [name]` to list and switch output styles, including over Remote Control and in cloud and other headless sessions
- Added a diff of the files a Bash command changed to the Bash tool result when the Bash tool handles file edits (setting `bashEditDiffEnabled`)
- Added `OTEL_METRICS_INCLUDE_REPOSITORY` to tag OpenTelemetry metrics and events with `vcs.*` repository attributes; commit events get `vcs.ref.head.*` with `OTEL_LOG_TOOL_DETAILS`
- Added `CLAUDE_CODE_GATEWAY_MODEL_DISCOVERY_TIMEOUT_MS` to extend the LLM gateway `/v1/models` discovery timeout (default 3s)
- Added a spinner tip suggesting `/focus` for a view with just your prompt, a one-line work summary, and the response
- Added `CLAUDE_CODE_WORKFLOW_MAX_CONCURRENT_AGENTS` (1–256) to raise the Workflow tool's per-run concurrent agent limit for inference-bound fan-outs
- Fixed the prompt cache being partially invalidated on the turn after a response was cut off at the output-token limit and automatically resumed
- Fixed a case where resuming a session after interrupting Claude mid-thought could change how earlier context was re-sent, hurting prompt-cache reuse
- Fixed F1/F2/F4 not working in kitty-protocol terminals and Delete in st, Alt+arrows acting as Escape in rxvt-unicode, and Shift+punctuation typing the unshifted key in WezTerm (regression in 2.1.247)
- Fixed remote and headless sessions reporting "waiting for your input" while background agents were still running (set `CLAUDE_CODE_BG_TASKS_REPORT_RUNNING=0` to restore the old behavior)
- Fixed the terminal's replies to capability queries (`^[[?1;2c`) appearing as stray text at startup in some terminals
- Fixed rows at the top or bottom of the transcript going blank in fullscreen after resizing the terminal
- Fixed a deny or ask permission rule starting with `!` applying beyond the settings source that wrote it; such a rule now applies only within its own source, and a bare `!` negation is ignored
- Fixed the git status Claude is told after a compaction: it is now the current status, not the one from the start of the session
- Fixed synced plugin MCP servers not connecting when a remote session resumes
- Fixed resumed headless sessions losing a turn's replies when the model was switched or a request was retried mid-turn
- Fixed terminal escape codes, line breaks and oversized text from a background task's on-disk record reaching the task list and task notifications when work is resumed
- Fixed CMYK JPEG images failing to attach with "cannot decode"; they are now converted and resized like other JPEGs
- Fixed the managed settings approval dialog not naming the collector for a gRPC telemetry endpoint set without a scheme
- Fixed plugin `headersHelper` consent prompts showing a URL path that could be misread as a different host
- Fixed plugin errors showing `[redacted URL]` in place of a relative Windows path with a folder name that starts with `@`
- Fixed missing cursor in the permission-rule, auto-mode-rule, add-directory, session-rename and feedback-review text fields when the terminal's native cursor is enabled
- Fixed repeated clicks on a `/fork` receipt, each under a second apart, never backgrounding the session right away while it waited for the current tool to finish
- Fixed plugin LSP servers that reject `shutdown` params (e.g. rust-analyzer) being left running at session end; `exit` is now sent even if `shutdown` fails
- Fixed the attribution reminder overriding a CLAUDE.md or memory rule against commit and pull request attribution; lines set by managed settings still apply
- Fixed prompt suggestions being dropped for text in Japanese, Chinese, Thai and other languages written without spaces between words
- Fixed synchronized output being assumed from the terminal's name in GNOME Terminal and Konsole versions that do not support it
- Fixed `permission_denials` in `--output-format stream-json` results omitting Read, Edit and Write calls blocked by a path-scoped deny rule
- Fixed sessions run through the SDK or the desktop app showing an unknown status in other sessions' agent list
- Fixed `/insights` failing on Bedrock, Vertex, Foundry, and gateway deployments whose account can't reach the default Opus model by using the session model there instead
- Fixed organization policy limits not loading for the session when another Claude Code process refreshed the login at the same moment
- Fixed Claude Desktop sessions using Bedrock, Vertex, or a gateway not getting the contextual "what Claude needs" turn-end notification text
- Fixed MCP servers reconnecting when an updated config only changed the order of the server URL's query parameters
- Fixed the prompt box's top border splitting into extra lines when viewing a background agent whose name or description has line breaks or is wider than the terminal
- Fixed sessions getting permanently stuck on "Prompt is too long" when auto-compaction had no complete earlier exchange to summarize (mostly Agent SDK sessions with very large prompts)
- Fixed `/goal` runs silently stalling after API errors, network drops, or token limits: the goal now retries with backoff, or pauses and says why, including until a usage limit resets
- Fixed prompt cache misses in cloud sessions by waiting briefly for server configuration before the first request
- Fixed `/btw` answers that contained made-up tool calls and output: the side question is now told not to write them, and any that appear are flagged as not executed
- Fixed `CLAUDE_CODE_RESUME_INTERRUPTED_TURN` re-running a turn that had failed with an API error over 6 hours earlier, or longer ago than `CLAUDE_CODE_RESUME_INTERRUPTED_TURN_MAX_AGE_MS` when set
- Fixed organization plugins enabled through managed settings not loading in headless sessions and on Claude Desktop (once Desktop bundles this CLI version); they load from the next session
- Fixed plugin archives extracted for a session being readable by other local users, extracted files keeping world-writable bits from the archive, and stale files surviving re-extraction
- Fixed `Edit()` deny rules and the write-path check not applying to the file a Bash `tee` command writes; a `Bash(tee:*)` allow rule no longer covers destinations outside the working directories
- Fixed stray characters like `22c`, or a terminal's color or version reply, being typed into the prompt at startup over slow connections (ssh, browser terminals)
- Fixed the terminal's block cursor showing under the interface in rxvt-unicode after leaving or re-entering fullscreen
- Fixed the cursor block staying visible after returning from an external editor in fullscreen mode on rxvt-unicode
- Fixed the interface being drawn twice after returning from an external editor (Ctrl+G) outside fullscreen mode
- Fixed the interface being drawn twice in Konsole after returning from an external editor
- Windows: Fixed PowerShell tool commands sent to the background stopping when Claude Code exits
- Improved the `/diff` panel to open fully rendered in one step instead of showing a loading state first
- Improved prompt suggestion filtering for Japanese, Chinese and Korean text: mixed-script and single-word suggestions are kept, and meta or evaluative text is dropped as it is for English
- Improved the Skill tool's "Unknown skill" error to name the plugin skill's full name when a bare name matches exactly one plugin skill
- Improved keyboard support over SSH and in unrecognized terminals: terminals that answer the kitty keyboard query (such as foot and Alacritty 0.16+) now get Shift+Enter and Ctrl+Shift shortcuts
- Improved responsiveness in long sessions: transcript updates no longer re-process the whole conversation to build the collapsed tool-use summaries
- Improved first-party sessions with telemetry disabled: an `alwaysLoad` MCP server that finishes connecting mid-conversation is usable on the next turn without a tool-search round trip
- Changed `/ultrareview --post` to post the PR comment directly when the findings arrive and print the comment link, instead of starting a second cloud session to post it
- Changed artifact database reads that save into the session scratchpad so they no longer stop for working-folder approval
- Changed skills synced from claude.ai in cloud sessions to be named `anthropic-skills:<name>`, matching Claude Desktop; the bare name still works when nothing else uses it
- [VSCode] Added an agent map: an "N agents" footer pill opens a map of the session's sub-agents with per-agent cards, Stop agent, and read-only transcripts
- [VSCode] Added a Hooks dialog to the command menu for viewing hooks and adding, editing, or removing them in user, project, and local settings; managed, plugin, and session hooks stay read-only
- [VSCode] Added live progress rows for running subagents under the tool-call groups in Focus view
- [VSCode] Added a Permission rules dialog that lists permission rules and adds or removes them in user, project, and local settings; startup-option, session-only, and managed rules stay read-only
- [VSCode] Added a Cancel button to the Switch account screen that returns to your session as the current account
- [VSCode] Fixed Focus view showing a turn started by a delivered plain-text prompt, such as a scheduled task's, as part of the previous turn
- [VSCode] Fixed the footer's prompt cache clock hiding its minutes when the panel is narrow
- [VSCode] Fixed the session list keeping sessions from the default folder when `CLAUDE_CONFIG_DIR` is set in a settings file or the `environmentVariables` setting
- [VSCode] Fixed a plan preview that finished loading late sometimes hiding its comment box or showing an older plan
- [VSCode] Fixed a plan preview accepting comments that went nowhere after its Claude tab closed
- [VSCode] Fixed the prompt cache clock and reopen notice for a session compacted after its last reply and then closed, which now reads as cold when reopened
- [VSCode] Fixed a session renamed in the extension while Remote Control is on keeping its old name on claude.ai/code
- [VSCode] Fixed the "Enable Remote Control for all sessions" toggle keeping its last position after the setting was reset to default from a terminal
- [VSCode] Fixed restored Claude tabs not counting as open in the session list after a window reload until clicked, and their row opening a second tab
- [VSCode] Fixed Switch account making a tab forget its dismissed usage-limit warnings when you sign back in as the same account
- [VSCode] Fixed a session rename being replaced by the generated name after a window reload when the session was renamed during a long turn
- [VSCode] Fixed the sidebar usage meter keeping a stale per-model weekly limit row after the account loses that limit
- [VSCode] Fixed a rare case where an @-mention sent with the keyboard shortcut while a new chat view was still starting could be inserted into the input long after the keystroke
- [VSCode] Fixed the session list jumping down when the Account & usage header appeared a moment after opening the Claude side bar
- [VSCode] Improved documents and messages written for someone other than the user: Claude now writes them for that audience and names it at the top of its reply
- [VSCode] Improved screen reader and keyboard accessibility in the slash-command menu, @-mention menu, output-style picker, Send/Stop button, permission and question cards, and onboarding checklist
- [VSCode] Changed the current-file chip in the message box: an X now removes it, replacing the Hide toggle
- [VSCode] Removed the Claude Code items from a session tab's right-click menu and the editor title bar's "..." menu; they could not act on the tab the menu was opened on
- [Claude Code on the web] Added taking back a queued message in a cloud session before Claude reads it: remove it from the queue, or press Esc or Up, and the text 

these notes continue in the original release.

- Added to the Claude apps gateway: with `pricing:` set in `gateway.yaml`, signed-in Claude Code clients receive the same rates through managed settings, so `/cost` and telemetry match the spend meter
- Added a startup warning for gateways when `access_control.allow_cidrs` is empty, and a one-time warning the first time a request arrives from a public address
- Added the `gatewayInternalNetworks` managed setting, letting administrators allow `/login` to a Claude apps gateway on their organization's own public IPv4 block
- Added `claude self-hosted-runner --remove-session-state` (default off): delete each session's per-session directories under `<base-dir>/_sessions/` when the session ends
- Added `configDirectory` to the output of `claude auth status --json`
- Added `--json` to `claude plugin install`, `uninstall`, `update`, `enable` and `disable`, and `errorDetails`/`noteDetails` to each row of `claude plugin list --json`
- Added browser-tab icons for published artifacts, chosen by Claude to match each page
- Fixed every turn failing with HTTP 400 on third-party Anthropic-compatible endpoints (`ANTHROPIC_BASE_URL`) since 2.1.265: a regex in the Artifact tool's input schema that those endpoints reject
- Fixed WebFetch hanging indefinitely on a server that keeps the response open without finishing; a fetch now fails after 300 seconds. Set `CLAUDE_CODE_WEBFETCH_DEADLINE_MS` to override the deadline (0 turns it off)
- Fixed a respawned in-process teammate picking up tools or a system prompt from a same-named agent file in a folder you have not trusted
- Fixed sustained high CPU usage: a busy loop in long-running idle sessions no longer pins a CPU core, and rapid terminal focus reports during a session recap no longer keep the CPU high
- Fixed Claude sometimes replying "your message came through empty" after an MCP tool call
- Fixed deny and ask permission rules on symlinked directories (`/etc`, `/tmp`, `/var` on macOS; `/bin` on Linux) not applying when a path was given by its real location, and Bash commands ignoring deny rules written on a symlinked path spelling
- Fixed a case where a Read or Edit deny rule did not apply when an `env -C`, `eval` or similar command the permission checker cannot analyze was on the same line
- Fixed plugin and marketplace errors showing a token or password from a git source URL
- Fixed `/mcp` and `/plugin` server details, `claude mcp list`/`get`, and MCP login errors showing secrets resolved from `${VAR}` placeholders in MCP configs
- Fixed prompt caching and extended thinking breaking mid-session for SDK sessions using `excludeDynamicSections`: the first message is no longer re-rendered each request
- Fixed entitled users being told a model is restricted after restart or in the Desktop Code tab when a cached model-access denial was stale
- Fixed a running session silently switching to the organization's default model when another Claude Code process refreshed a stale model-access entry
- Fixed long-context 429s on Fable models showing the usage-credits consent prompt instead of the 1M-context message on Pro and Team plans
- Fixed workload identity federation via a profile (as claude-code-action configures it): processes sharing the profile could fail mid-run with `401 … jti reused`
- Fixed MCP server OAuth sign-in failing with "No available ports for OAuth redirect" when the local callback port range can't be bound
- Fixed the conversation summary produced by `/compact` and auto-compact mangling text that contained `$` sequences
- Fixed resuming a conversation that ended with `/compact`: its restored-file notes now load in the same order on every resume
- Fixed SDK prompt suggestions, side questions and `/rename` sending the conversation from before a compaction
- Fixed `@` file and `/` command suggestions not appearing after recalling a previous prompt with the up arrow and editing it
- Fixed `claude agents`: pressing ← again at a natural pace to go back to the agent list no longer gets ignored until you pause for over a second
- Fixed `claude agents` session delete getting stuck when a worktree can't be removed: the message names the cause and next step, and for a git worktree ctrl+x again deletes the directory anyway
- Fixed background agent and workflow rows in the agents panel expanding to many lines when their text contained line breaks
- Fixed Claude in Slack sessions losing their Slack tools when org managed settings set an MCP allowlist
- Fixed Claude in Chrome asking to allow the host "https" when a navigation URL had a scheme but a host that could not be parsed
- Fixed the spinner wrapping onto several lines when the current task's label is long; the label and the "Next:" task line now stay within one terminal row
- Fixed the `/bug` and `/feedback` description field showing no cursor when the terminal's native cursor is enabled
- Fixed Remote Control sessions served by `claude remote-control` showing a generated name instead of their session title in `ListAgents`
- Fixed `claude plugin validate` rejecting plugin paths whose directory name begins with two dots, which the plugin loader accepts
- Fixed plugins silently skipping a default monitors file or root SKILL.md that could not be checked
- Fixed WebFetch's error for localhost and other dotless hostnames to explain why the URL is refused and suggest curl
- Fixed PermissionRequest hooks not firing in `--print` mode
- Fixed policy-helper warnings not printing on headless (`-p`) runs
- Fixed `/resume` listing a `/fork` background session under its parent's name instead of its own `⑂` fork name
- Fixed `/remote-control` and other claude.ai-gated commands to suggest `/login` when signed out instead of showing a Claude for Enterprise migration message
- Fixed `CLAUDE_CODE_SESSIONEND_HOOKS_TIMEOUT_MS` not extending SessionEnd hooks that have no per-hook `timeout` (they were still cancelled after 1.5 seconds)
- Fixed `/autofix-pr` and other cloud-session commands saying to retry or install the Claude GitHub App when no GitHub account is connected; they now point to `/web-setup` or the web connect page
- Fixed cloud-session commands such as `/teleport` and `/remote-env` to explain when an organization policy turns them off, instead of answering "Unknown command"
- Fixed Bash sandbox instructions over-stating confinement: no unenforced path lists when filesystem isolation is off, and strict mode no longer claims commands can never run unsandboxed
- Improved fullscreen mode: adding or removing a prompt line (Shift+Enter) now repaints as fast as typing a character instead of re-rendering the visible transcript
- Improved `--continue` / `--resume`: the conversation appears immediately instead of waiting for SessionStart hooks, and the first message no longer re-reads the whole transcript
- Improved responsiveness during tool-heavy turns by no longer redrawing the transcript for a hidden per-tool-batch reminder
- Improved startup time in projects with `.claude/workflows/` scripts: listing them no longer parses each script
- Improved auto mode denials: the message Claude receives now names the rule that blocked the action and asks Claude to try a safer method and finish unrelated work before stopping to ask you
- Improved Claude in Chrome: long page reads now stay inline instead of being saved to a file and read back
- Improved the MEMORY.md truncation warning to say how many lines were cut and where the cut starts
- Improved the terminal permission prompt for artifacts: it now leads with the ask's question
- Improved the prompt footer: an editor or `/diff` selection now shows inside the prompt input, and fullscreen mode shows Remote Control status in the header instead of the footer
- Improved the "Usage credits required for 1M context" message to say that usage credits turned on mid-session take effect after restarting Claude Code
- Improved `/plugin`: installing, enabling or disabling a plugin now takes effect when you close the menu; `/reload-plugins` is no longer needed afterwards
- Changed the system prompt on Bedrock, Vertex and Foundry to deliver environment, model and settings details as attachments, matching first-party sessions
- Changed Bedrock, Vertex and Foundry sessions to keep the tool list byte-stable across a conversation (late-connecting tools load deferred instead of rewriting it), matching first-party sessions
- Changed the task-tracking tools (TaskCreate/Get/Update/List, TodoWrite) to be offered only on Claude 3.x, Opus 4.0–4.7, Sonnet 4.0–4.6, Haiku 4.5; set `CLAUDE_CODE_ENABLE_TODO_TOOLS=1` elsewhere
- Changed the artifact data-edit permission prompt in the terminal to a card that shows the document count and who can open the artifact
- Changed local Cowork sessions set to skip all approvals: the Artifact tool now refuses a local file outside the session's folders, or behind a symlink, instead of reading it without asking
- Changed plain `WebFetch` deny and ask rules to no longer apply to Artifact tool reads and updates; use an `Artifact` rule (or `WebFetch(domain:claude.ai)`) to block or gate them
- Changed the "N MCP servers need authentication" startup notice to announce each server once instead of at every launch
- [VSCode] Fixed the session list, settings toggles, and chat tabs when `CLAUDE_CONFIG_DIR` is set in a settings file or the `environmentVariables` setting
- [VSCode] Fixed the model pill, model picker and command menu going blank in open tabs for a few seconds after a login, logout or account switch
- [VSCode] Fixed Auto disappearing from the mode picker in new-tab or just-reloaded conversations when a project or local setting overrides the model named in `~/.claude/settings.json`
- [VSCode] Fixed session names reverting to the last prompt after a window reload when a SessionStart hook is configured
- [VSCode] Fixed the footer's model pill and Remote Control pill waiting for the new tab's Claude process to start when another tab in the window is already up
- [VSCode] Fixed a second Claude process running through its full startup when a session tab's launch arrived more than half a second after its config read
- [VSCode] Fixed resuming a session from the session list ignoring `claudeCode.preferredLocation: "sidebar"` (it always opened a panel), and programmatic opens resetting that setting to "panel"
- [VSCode] Fixed Windows issues: the WSL install prompt no longer appears on machines without WSL installed, and IDE diagnostics are now returned correctly for Windows files when WSL is installed
- [VSCode] Fixed the custom style builder saving a User level style in a folder the CLI does not read when `CLAUDE_CONFIG_DIR` is set through settings
- [VSCode] Added Left and Right arrow keys to change where an always-allow permission rule is saved, for keyboard and screen reader users
- [VSCode] Added a "Claude Code: Focus last message" command that moves keyboard focus to the newest message in the conversation, for keyboard and screen reader users
- [VSCode] Changed the Manage plugins dialog to apply installs, enables, disables and uninstalls to open sessions without a restart
- [VSCode] Changed some artifact permission prompts to omit the "don't ask again" choice, matching the terminal
- [Claude Code on the web] Fixed cloud sessions running longer than about six hours silently losing files saved to persisted session folders; saves now persist for up to a day
- [Claude Code on the web] Fixed "Invalid effort level" errors when a routine resumes a session, or a session starts with no set effort, in orgs where an admin caps a model's effort
- [Claude Code on the web] Improved routine creation from a conversation: when the new routine has no connectors, Claude now says so and how to add them instead of only confirming it
- [Claude Tag] Fixed the admin settings page hanging on a loading skeleton or going blank after a transient load failure; a section that fails to load now shows a Retry button
- [Claude Tag] Added a link from a Slack channel's configure page back to

these notes continue in the original release.

- Added `maxEffortLevel` setting (top-level or per model under `modelSettings`): caps the effort level on every provider, including Bedrock, Vertex and Foundry; users can still pick a lower level
- Added `--system-prompt-snapshot off` to render the system prompt fresh on every request instead of reusing the conversation's recorded prompt (for iterating on prompt text)
- Fixed Cowork scheduled tasks in the cloud failing at startup for organizations whose managed settings require sandboxing
- Fixed `/context` and other local command output rendering blank on mobile clients
- Fixed shift+enter and option+backspace not working after reconnecting to a tmux or ssh session inside an agent view
- Fixed the dim last-prompt header not appearing at the top of the conversation when scrolling up in fullscreen mode
- Fixed Workflow `agent()` calls with large output schemas being refused in auto mode instead of being checked by the safety classifier
- Fixed a case where a marketplace entry path containing a backslash could bypass the containment check for fetched marketplaces on macOS and Linux
- Fixed expired AWS or Google Cloud credentials under a host app such as Claude Desktop retrying ten times with a generic "request failed" before the re-authenticate error appeared
- Fixed resuming a session after `/compact` or another slash command ran via `-p --resume`: a spurious "Continue from where you left off." turn is no longer inserted
- Fixed resuming a large session (transcript over 5 MB): parallel tool calls and their hook output are no longer dropped from the reloaded conversation
- Fixed managed `allowedHttpHookUrls`, `httpHookAllowedEnvVars` and `allowedChannelPlugins` to admit nothing, not everything, when unreadable
- Fixed `/login` on machines whose managed settings require Claude apps gateway sign-in: Esc now closes the dialog instead of doing nothing
- Fixed artifact publishes cut off by a dropped connection mid-upload: they now retry once when Claude Code can tell the upload never completed, instead of reporting an unknown outcome
- Fixed `effort:` frontmatter on custom commands, skills, and subagents being ignored on models whose default effort is still pinned (Opus 4.7, Opus 4.8, Fable 5)
- Fixed artifact publish failing with an unhelpful error when the page file isn't valid UTF-8 or contains a replacement character (U+FFFD); the error now names the line and column to fix
- Fixed `claude agents` `@` directory menu not listing repositories created after the session started
- Fixed Remote Control clients that join a Claude Desktop or VS Code session showing a stale permission mode until it was changed again
- Fixed `claude remote-control` exiting and dropping every attached session when its server credential expires (about 30 days after start); the host now re-registers and keeps going
- Fixed the usage-limit warning flickering on and off during a session when requests for different models or modes report different limit windows
- Fixed earlier reasoning being dropped when an MCP server re-sends, or a built-in tool re-renders, a tool the model already loaded
- Fixed a tool that disappears mid-conversation, from a disconnected MCP server or an upgrade, rewriting the tool list and discarding earlier thinking
- Fixed a background worker forked from a conversation adding EnterWorktree to the conversation's tool block mid-session, which broke prompt-cache reuse
- Fixed mid-session MCP and plugin tools being added to the tool list in sessions without ToolSearch, which broke prompt-cache reuse; supported models now receive them as deferred definitions
- Fixed switching models with /model re-sending every tool definition (a prompt-cache miss); commit and PR attribution text now arrives as a conversation note that updates on model changes
- Fixed resumed sessions rewriting the inline tool set when an MCP connector reconnects at a different moment than before
- Fixed resumed sessions re-rendering tool descriptions instead of replaying the recorded ones when the first turn ran a tool
- Fixed prompt-cache misses and dropped extended thinking when a claude.ai connector's tools change between a session and its resume
- Fixed resumed sessions rewriting earlier MCP tool announcements (and dropping extended thinking) before their connectors reconnect
- Fixed a prompt-cache break when a print-mode (`-p`) conversation is resumed interactively: the system prompt prefix no longer changes
- Improved the `/diff` panel: it no longer flashes "0 files changed" and a spinner before settling, and its empty state is centered in the panel
- Improved the Bash tool's description guidance so Claude describes what a command does in plain words instead of echoing the command
- Improved sandbox guidance so Claude suggests `/copy` when clipboard commands such as `pbcopy` fail inside the sandbox
- Improved `--resume` first-render time for sessions with many Bash tool calls
- Improved prompt input responsiveness: keystrokes no longer occasionally wait a frame behind spinner or streaming repaints
- Improved prompt-cache stability: subagents and sessions started with `--system-prompt` or `--append-system-prompt` now record the system prompt and tool definitions once instead of re-rendering them
- Improved Artifact tool publish errors: when a publish is refused, the message now says why and what to do about it
- Self-hosted runner: Changed `--use-anthropic-git-proxy` to be reported to the server at registration and to print a warning for each session that still clones through the legacy git proxy
- Gateway: Changed `forward_user_identity` upstreams to return a 429 as-is to a developer whose email was forwarded, instead of failing over to the next upstream, so the proxy's per-user limits hold
- [VSCode] Fixed the extension host hanging at 100% CPU when forking, editing an earlier message, or rewinding in a conversation whose saved transcript contains a cyclic parent link
- [VSCode] Fixed pasting a screenshot on WSL2/WSLg inserting raw image bytes into the chat input; the image is now attached when the clipboard provides it, otherwise the paste is ignored
- [VSCode] Fixed chat diff blocks always rendering with a dark editor theme; they now follow the active VS Code color theme, including high contrast
- [VSCode] Fixed mixed right-to-left and English text rendering in the wrong order while typing in the message input
- [VSCode] Fixed accepting an edit in the diff view on a file with Windows (CRLF) line endings failing with "String not found in file"
- [VSCode] Fixed @-mentions dropping files whose paths contain spaces
- [VSCode] Fixed the sessions list view failing to load in windows connected over Remote-SSH when the workspace folder exists only on the remote host
- [VSCode] Fixed runaway ripgrep processes when viewing files in large or symlink-heavy workspaces
- [Claude Code on the web] Fixed GitHub Enterprise Server sessions showing your GitHub account as disconnected once its token expired; PR and issue operations now refresh it automatically
- [Claude Code on the web] Fixed `gh` and GitHub API calls failing in organizations without the Claude GitHub App; they now use your connected GitHub account and say so when none is connected
- [Claude Tag] Added a "Use a custom connector" link to the preset connection forms in Claude Tag admin settings, so you can switch to a custom connection without starting over
- [Claude Tag] Fixed Claude replying "The API rejected the request as invalid" when the organization has run out of usage credits; the reply now says so and explains how to add more
- [Claude Tag] Fixed thread requests to edit or delete a message Claude posted at the channel's top level being answered with a correction instead of reaching the session that posted it
- [Claude Tag] Fixed **Connect** on Tool access requests under Admin settings > Review requests failing with "Authorization failed" or showing the requested access bundle as deleted

- Fixed a 2.1.265 regression affecting LLM-gateway and proxy setups: the undocumented `CLAUDE_CODE_USE_GATEWAY` environment variable, previously ignored unless `ANTHROPIC_BASE_URL` and `ANTHROPIC_AUTH_TOKEN` were both set, began forcing Cloud-gateway sign-in on its own in 2.1.265, so configurations that set it alongside an API key, `apiKeyHelper`, or custom auth headers failed every request with "Not signed in to the Cloud gateway". The variable on its own is ignored again; no configuration change is needed

- Added `user.email` and `user.groups` to the telemetry Claude Desktop and Cowork send through a Claude apps gateway, matching terminal sessions
- Added support for pointing `--plugin-dir` at a folder of plugins: each child folder with a manifest loads, and children added or removed while running are picked up
- Added a 1 GB cap on tool results saved to disk; the in-conversation preview says when a saved file was truncated
- Fixed resuming a foreground-spawned subagent changing its tool list and system prompt prefix, which broke prompt-cache reuse for that agent
- Fixed agent teammates and resumed subagents moving SubagentStart hook context and preloaded skills out of the prompt prefix on later turns, which broke prompt-cache reuse
- Fixed resume after the previous process died while a tool was running: the last prompt is no longer rewritten, and the interrupted tool call is kept and marked interrupted
- Fixed `/model opusplan[1m]` being rejected with "Model not found"
- Fixed syntax-highlighted code in permission prompts and messages sometimes omitting a character after a Ruby `?`, Erlang `$`, or Perl `$` sigil
- Fixed the fullscreen transcript jumping by one row whenever the slash-command or @-file suggestion list opened or closed
- Fixed a plugin path containing a backslash bypassing the symlink containment check on macOS and Linux
- Fixed plugin directories whose names begin with two dots being wrongly refused as outside the plugin root
- Fixed VS Code and SDK sessions occasionally requiring re-login when a session was closed while refreshing its token
- Fixed Remote Control sessions sending the end-of-turn signal before the reply's last message, which could show a reply as finished in the Claude app before its last part arrived
- Fixed background (`--bg`) sessions occasionally being retired mid-turn when a message arrived just before the idle timeout
- Fixed Claude Code's own git status and diff probes running clean filters configured by a nested repository inside the working tree
- Fixed the advisor tool and its instructions being re-decided per request from the request's model; the decision is now made once and announced in the conversation when it changes
- Fixed artifact publish accepting connector tool names the connector doesn't expose; the publish is now refused when none of the declared tools exist, and warned when only some don't
- Fixed `/add-dir <subdirectory>` refusing to load a subdirectory's agents when managed settings lock only skills to plugins, and promising agents when only agents are locked
- Fixed two-key keyboard shortcuts cancelling silently when the second key arrived more than a second later, as happens inside tmux; they now wait 3 seconds and show a notice when they time out
- Fixed forked skills (`context: fork`) not streaming their kickoff prompt and, with `--forward-subagent-text`, their text turns as progress events in stream-json
- Fixed a plugin's default component folder that the OS cannot check, such as a symlink loop, being silently skipped; it is now reported in `/plugin` with the error code
- Fixed the Claude apps gateway's OTLP telemetry relay pausing all forwarding to a collector for 30 seconds after it rejected a few payloads as malformed or too large
- Fixed `/plugin` Discover/Browse and `claude plugin list --json --available` showing no description or display name for marketplace plugins whose metadata lives only in their `plugin.json`
- Fixed `/login` showing "no gateway URL is configured" when re-run in a session that signed in to a Claude apps gateway set by managed settings
- Fixed `/model` claiming a model was "saved as your default" when the settings file couldn't be written; it now says the save failed and why
- Fixed `/clear` from Remote Control waiting on SessionStart hooks and on open terminal dialogs before completing
- Fixed the `/config` dialog changing height when switching between its tabs
- Fixed resuming a workflow run after its container restarted; a resume whose run journal is missing now fails with a clear error instead of rerunning every agent
- Fixed the `claude-api` skill's error-code reference: model access failures return 404 and unavailable beta headers return 400, not 403
- Fixed non-interactive sessions (`-p` with stream-json input, Agent SDK, cloud sessions) resetting the shell working directory at each new user message; a `cd` now persists across turns
- Fixed MCP servers configured as `http` that only speak the legacy HTTP+SSE transport never connecting; Claude Code now falls back to SSE as the MCP spec describes
- Fixed some claude.ai connectors in cloud sessions showing as needing authentication even though they are connected in claude.ai (servers that answer an unsupported request with HTTP 401)
- Fixed remote sessions keeping their sandbox container alive while a connector approval or sign-in link waits for you
- Fixed resumed sessions showing long model-facing recovery instructions in "background task didn't finish" notices instead of a short status line
- Windows: Fixed Read, Write and Edit refusing every file ("symlink resolution changed after permission was checked") when running inside an AppContainer or restricted-token sandbox
- Improved `--worktree` startup on large repositories: the new worktree is now checked out in parallel (git 2.32+)
- Improved `/workflows` agent detail: tool calls are marked running, failed or done, the subagent's task list is shown when it has one, and Enter unfolds the listed calls with their inputs and results
- Improved slash commands typed mid-prompt: matches now show in a list (Tab opens it outside fullscreen) instead of a single suggestion, and a plugin skill is now found by its bare name
- Improved remote MCP servers that need sign-in: Claude Code no longer registers an OAuth client with them until you actually authenticate
- Improved the time to resume long sessions that read many files
- Improved the error shown when an image over the size limits cannot be decoded: it now names the cause and how to fix it instead of only citing the limit
- Improved the Artifact tool's read of an artifact someone else wrote: the summary now treats the page as untrusted content and flags embedded instructions rather than relaying them
- Updated the `.claude` folder permission option to say what it actually allows: editing files in the project's `.claude` folder (or `~/.claude`) for the session
- Changed machines with `forceLoginGatewayUrl` in managed settings to be Claude apps gateway sessions from startup, like `forceLoginMethod: "gateway"`; a leftover claude.ai login or API key is not used
- Changed image processing to use the runtime's built-in image support; the CLI no longer extracts a native image module to the temp directory
- Changed plugin display metadata to prefer the marketplace entry over `plugin.json` on the Installed tab and `claude plugin details`, filling gaps from `plugin.json`
- Changed Claude apps gateway sessions to export OpenTelemetry directly to a collector the gateway's managed settings name in `OTEL_EXPORTER_OTLP_ENDPOINT`, instead of through the gateway's relay; sessions without a named collector still use the relay
- [VSCode] Added automatic archiving of sessions inactive for a set period (new "Archive inactive sessions" setting, default 14 days)
- [VSCode] Fixed the sidebar chat coming back blank after Reload Window or a restart when the conversation had been open for more than 10 minutes
- [VSCode] Fixed the timeline dot sitting below the text on the "Remote Control is active" message

- Bug fixes and reliability improvements

- Added an "Organization policy" line to `/status` and `claude doctor` that says why your organization's policy could not be loaded, such as a proxy not passing the endpoint through
- Added `bashOutputMaxChars` and `taskOutputMaxChars` settings to raise how much command and background-task output Claude receives inline before it is saved to a file, up to 128K characters
- Added `--append-subagent-system-prompt-file` to read the subagent system prompt from a file, for prompts too large to pass on the command line
- Added `/skill-doctor` to show which loaded skills go unused and what they cost in context, so you can prune them
- Fixed typed or pasted characters occasionally landing out of order or being dropped during fast input or key repeat
- Fixed `/add-dir <subdirectory>` printing a false "couldn't be resolved" error when the working directory is on a `/net` automount
- Fixed the Bedrock setup wizard hanging when AWS or an AWS credential helper never responds (it now times out with a clear error), and its model checks failing behind a TLS-inspecting proxy
- Fixed cloud sessions discarding a plugin synced from claude.ai when managed settings force-enable it in `enabledPlugins`, then falling back to a marketplace clone that could fail
- Fixed being unable to delete the character immediately before an inline `[Image #N]` chip in the prompt input
- Fixed resuming a session losing hook output and other context around parallel tool calls, which changed the resumed request
- Fixed Remote Control showing a stale permission mode when a phone, browser, or claude.ai app attaches to a terminal session or after the mode changes in the terminal
- Fixed Remote Control sessions showing as still working (stuck spinner and Stop button) after stopping a turn from a connected phone or browser, or after a local slash command like `/clear`
- Fixed SDK and cloud sessions ignoring a Stop or interrupt sent just after the first prompt, before the turn had started; the turn now stops instead of running to completion
- Fixed Remote Control uploading a session pulled with `/teleport` into the connected session, which appeared appended to the original on phone and web
- Fixed Remote Control's inbound event stream failing behind TLS-inspecting corporate proxies on native Windows
- Fixed Remote Control sessions showing the default effort level on claude.ai when the effort comes from settings
- Fixed `gcpAuthRefresh` opening a browser at startup when the Google credential check was slow, even though the credential was still valid
- Fixed claude.ai connectors staying absent for the whole session when the startup connector fetch timed out — the CLI now retries in the background
- Fixed sustained high CPU usage when a background agent could not be resumed and its wake-up was retried in a tight loop
- Fixed feature flags gated to a newer version occasionally applying to an older Claude Code version running on the same machine
- Fixed `/usage` and the VS Code usage panel dropping a model-specific weekly limit row when the usage endpoint is rate limited or when opened right after startup
- Fixed `claude -p --resume <file>` adopting a malformed session ID recorded in the transcript; it now resumes under a fresh session ID instead
- Fixed the terminal progress indicator (iTerm2, Ghostty, ConEmu) showing the session as finished while a background workflow or agent was still running
- Fixed a rare layout glitch where a box could render with the wrong height after its container switched between row and column direction
- Fixed Claude apps gateway client IP when a trusted proxy appends a port to `X-Forwarded-For`; with an access list set, an unreadable entry now gets 403
- Fixed Claude apps gateway telling Claude Desktop to export OpenTelemetry as JSON even when the terminal CLI uses protobuf, so protobuf-only collectors rejected Desktop's data
- Fixed Desktop and web showing a session as busy while it only watches an artifact for updates
- Fixed Claude in Chrome `file_upload` failing with "paths: expected array, received undefined" in local Cowork sessions run from the Claude Desktop app
- Fixed `SendMessage` to an offline Remote Control session on another machine reading as delivered; the result now says delivery is queued until that machine reconnects
- Fixed plugin install hints from CLIs run in background Bash commands: they are now detected, and the raw `<claude-code-hint>` tag no longer leaks into the conversation
- Fixed in-process agent-team teammates re-sending their first-turn tool and skill announcements on the second turn, which changed the request prefix and missed the prompt cache
- Improved the `/model` picker and the VS Code model pill to show a model's name instead of its raw Bedrock, Vertex AI, or LLM gateway ID when Claude Code recognizes it
- Improved startup on Google Vertex AI when `GOOGLE_APPLICATION_CREDENTIALS` is set: API client creation no longer re-runs Google Cloud project discovery or spawns extra `gcloud` processes
- Improved streaming performance: already-rendered blocks are no longer re-checked by layout on each update
- Improved the dangerous-`rm` safety prompt to also catch `rm -rf` on positional parameters and inside double-quoted `sh -c` scripts
- Improved handling when the API sends no response headers: the retry now waits up to `API_TIMEOUT_MS` (10 minutes by default) instead of another 3 minutes, and the messages say what to change
- Changed a Claude apps gateway 403 on the managed settings load (at startup or after `/login`) to say Claude Code may not be enabled for the organization, instead of advising a new sign-in
- Changed machines whose managed settings pin `forceLoginMethod: "gateway"` to ignore a leftover API key or claude.ai login and ask for `/login`; Bedrock, Vertex AI, and Foundry sessions are unaffected
- Changed auto mode to treat a link that packs content into a public diagram renderer's URL as an upload to that site: no longer auto-approved unless you asked for it
- Changed the prompt's word-editing keys to match Bash: Ctrl+W deletes back to whitespace, Alt+F and Alt+D stop at word end, punctuation separates words; `keybindingFlavor` no longer has any effect
- Changed `/context` token counting to use a local estimate when the token-counting API is unavailable, instead of extra small-model requests
- [VSCode] Added a "Build a custom style" walkthrough to the Output styles menu that writes a custom output style file and lists it right away
- [VSCode] Added an Add server form and a Remove action to the MCP servers dialog, so MCP servers can be added and removed without leaving the IDE
- [VSCode] Added a hollow ring in the session list for sessions open in a terminal, another VS Code window, or Claude Desktop, so they no longer look closed
- [VSCode] Added a fold button to permission and question prompts so the conversation behind them can be read without dismissing them; the space beside the prompt now scrolls the conversation
- [VSCode] Added "Archive session" to the session list's right-click menu and gave Unarchive its own icon
- [VSCode] Fixed a session teleported from Claude Code on the web treating a question that was cut off when the cloud session shut down as declined
- [VSCode] Fixed the session tab's Rename box opening empty for a tab restored with the window; it now starts with the current name
- [VSCode] Fixed collapsed sections in the session list panel briefly showing expanded each time the panel loaded
- [VSCode] Fixed Focus view showing a tool call as still running after Claude had moved on, such as while a question waited for your answer
- [VSCode] Fixed the session list's active-row highlight going stale when an unfocused Claude tab's session ID is corrected
- [VSCode] Fixed Cmd/Ctrl+Shift+T reopen and deep-link opens placing the Claude tab outside the Claude editor group when a Claude tab has focus
- [VSCode] Fixed the session tab's "Add to group" putting a session opened from Claude Code on the Web in two groups; it now moves the entry the session list shows
- [VSCode] Fixed the model picker showing models an organization has since disabled until the window was reloaded twice
- [VSCode] Fixed a tab opened from the session list jumping back to that session, and a tab opened from a Web session restarting its teleport or staying empty, after VS Code reloads the tab's view
- [VSCode] Fixed `/btw` side-question history from earlier sessions being overwritten when a question is asked right after a window reload or while a settings file has errors
- [VSCode] Fixed the pending question card not reappearing after the Claude panel reloads when signed in with a Claude.ai or Console account
- [VSCode] Fixed claude.ai-only features staying visible in a window's other Claude panels after one panel picked up a third-party provider from a settings file
- [VSCode] Fixed the sign-in screen appearing despite the Disable Login Prompt setting when Claude Code reports no login or a request fails for lack of one
- [VSCode] Fixed the next queued permission prompt keeping text typed on the previous prompt and accepting an immediate second click
- [VSCode] Fixed install-plugin links opening the Claude sidebar without the install dialog in a window where only the session list had been shown
- [VSCode] Fixed the sidebar usage meter staying empty on a new window until the Account & usage dialog was opened, and a 0% usage limit being left out of the meter
- [VSCode] Fixed "Start new session in this group" losing the group after New conversation, and a missing unread dot for a session that finished before the sidebar's unread list loaded
- [VSCode] Fixed the editor tab badge showing unread during a running turn or missing on a tab opened from the session list, and "Add Session Tab to Group" doing nothing for an archived session
- [VSCode] Fixed "Enable Remote Control for all sessions" so flipping it also applies right away to sessions open in other VS Code windows
- [VSCode] Fixed the session list's Open filter for sessions continued from claude.ai whose tab was still recorded under the web session, and labeled the filter menu's sections for screen readers
- [VSCode] Changed the model picker to one flat list of every model, with rows kept for older model spellings listed last

- Added a diff panel that opens beside the conversation in fullscreen mode and shows your uncommitted changes as Claude edits; toggle it with `/diff`
- Added a likely cause for prompt-cache misses (e.g. tool definitions or system prompt changed, idle past the TTL) to `/cost` and the status line's `prompt_cache` field
- Added `/reload-plugins` to headless sessions, so it appears in the Claude Code Desktop and SDK command lists
- Added a text form of `/advisor` (`/advisor`, `/advisor <model>`, `/advisor off`) for the desktop app, Remote Control, and other headless (`-p`/Agent SDK) sessions
- Added `oidc.scope_on_refresh` to the Claude apps gateway for IdPs that return an id_token on refresh only when asked for `openid` again
- Added Claude apps gateway support for newer Claude Desktop keys in `desktop` policy blocks, including `userPluginMarketplacesEnabled` and `userPluginUploadsEnabled`
- Fixed `Edit`/`Write`/`Read` permission rules whose path contains parentheses being dropped as invalid or ignored by the Bash sandbox, which left "read-only" folders writable
- Fixed one file permission rule with an uncompilable pattern (e.g. an unclosed `[`) making every file edit fail with `Invalid regular expression`; such a deny rule now guards the literal path it spells
- Fixed Bash permission checks auto-approving zsh commands that hide a command substitution in a REPORTTIME, REPORTMEMORY or DIRSTACKSIZE assignment; these now prompt for approval
- Fixed Bedrock model discovery, token counting and AWS SSO/STS credential calls failing with "unable to get local issuer certificate" when the corporate root CA is only in the OS certificate store
- Fixed `permissions.blockReadsOutsideWorkingDirectories` on macOS hiding the user's git config from sandboxed git and hiding a worktree-isolated sub-agent's own checkout
- Fixed managed settings not loading for claude.ai Enterprise/Team users who also had a leftover API key from an earlier `/login`
- Fixed `/status` listing a signed-in claude.ai account and a configured API key as if both were in effect; the credential not in use is now marked
- Fixed managed `skillOverrides` entries keyed on a bundled skill's alias (e.g. `checkup` for `/doctor`) not applying, and `Skill(name)` deny rules not covering a nested skill listed as `<dir>:name`
- Fixed `model: fable` agents ignoring the `[1m]` tag on an `ANTHROPIC_DEFAULT_FABLE_MODEL` pin and silently running with a 200K context window
- Fixed the `/model` picker not showing Fable 5.1 for organizations that can use it, which was only accepted when typed as `/model claude-fable-5-1`
- Fixed prompt caching on Claude Fable 5.1 not covering the context attached after tool results, so it was re-sent as uncached input on every tool-call turn
- Fixed model switching staying blocked for the rest of the session after a plugin hook load failure; each switch now re-checks and the refusal names the cause
- Fixed model switching being blocked for the session when an organization-managed plugin's marketplace could not be loaded
- Fixed SDK-provided MCP servers (e.g. Desktop connectors) sometimes missing from the first turn and only appearing on the next one
- Fixed Claude in Chrome tools failing with "Not connected" mid-task in cloud-hosted claude.ai sessions when a connector was added or removed
- Fixed flags, joined emoji and accented letters splitting across wrapped lines, and stale text staying on screen when a flag or joined emoji falls in the terminal's last two columns (now shown as `…`)
- Fixed Remote Control accepting a model pick that is not a valid model name; it is now refused with an error instead of failing on the next message
- Fixed `/rewind` and `--rewind-files` reporting success when checkpoint backup files were missing and nothing was actually restored
- Fixed `/rewind` leaving stale file-read tracking from the rewound-away turns, which caused "File unchanged since last read" stubs and full-file re-injection after external edits
- Fixed `-p --resume`/`--continue` (as used by the desktop app) failing on every retry once a session's worktree directory lost its git metadata; it now fails once, then resumes without the worktree
- Fixed a subagent that resumed another agent via SendMessage never being woken by that agent's completion (the notification went to the main conversation instead)
- Fixed agent teams: an in-process teammate's transcript losing messages, or going blank, during long API retry waits (e.g. under `CLAUDE_CODE_RETRY_WATCHDOG`) as retry notices evicted real messages
- Fixed a session that moved to the background appearing twice in ListAgents (once as a phantom "interactive" twin with the same name) and receiving SendMessage deliveries in the viewer
- Fixed intermittent "task output swap refused" errors when many sessions share a project directory
- Fixed Ctrl+Z in fullscreen leaving the shell on the alternate screen, drawn over the paused interface
- Fixed Workflow tool subagents being restarted as stalled while a long context compaction was still in progress
- Fixed plugins from a URL marketplace failing to install with "marketplace entry path does not stay inside the marketplace directory" when a host app (e.g. Claude Desktop) stores it as a directory
- Fixed an extra browser tab opening when an artifact is published in a session you're driving from claude.ai, the desktop app, or mobile (Remote Control)
- Fixed the Artifact tool's first call failing with an "Invalid tool parameters" validation error in some Cowork sessions
- Fixed IDE line selections being dropped when running a skill or slash command (the "N lines selected" context now reaches Claude)
- Fixed repository detection for GitLab projects in nested subgroups (e.g. `gitlab.com/group/subgroup/project`)
- Fixed `owner/repo#123` issue references in rendered output linking to github.com when working in a GitLab repository; they now link to the gitlab.com issue
- Glob/Grep: Fixed the search path being probed on disk before the permission check; a missing path is now reported after permission is decided, as Read does
- Reverted the 2.1.259 change applying `Read()` deny rules to Bash arguments; it denied `npm run build` under a `Read(./**/build/**)` rule in every mode and made `cd … && grep` prompt even in auto mode
- Improved structured output: Workflow `agent({schema})` rejects a JSON Schema that can never be satisfied up front, and retry-cap errors now include the last validation failure
- Improved deleting a background session whose worktree has unpushed commits: the message now names the branch and commit count, and deleting again discards the worktree
- Improved the Claude apps gateway's refresh-failure log to name the step that failed
- Improved idle CPU usage of non-interactive (`-p` / SDK) sessions
- Improved the Claude apps gateway on Amazon Bedrock: input tokens for an aborted request are now counted with AWS's free CountTokens API (grant `bedrock:CountTokens`) instead of a one-token request
- Improved the settings error for rules such as `Edit(C:\dir\(name)\**)`, where `\(` is read as an escaped parenthesis rather than a path separator, to suggest an unambiguous spelling
- Improved auto-compact for 1M-context models: Opus and Fable sessions now compact shortly before the 1M-token limit, and recovery compaction on very large contexts no longer times out at 10 minutes
- Improved `/ultrareview` and `claude ultrareview` to wait up to 45 minutes (previously 30) for long-running cloud reviews
- Improved `/effort` on Claude Fable 5.1 so changing effort mid-session no longer invalidates the prompt cache
- Updated the bundled `claude-api` skill so its Go, Java, and C# samples use current-generation model IDs, and clarified that cheaper worker or sub-agent models should be current-generation too
- Changed `ctrl+l` / `cmd+k` in fullscreen mode to clear the transcript view like a terminal `clear`; scroll up to see earlier messages
- Changed permission rules with text after the closing parenthesis (e.g. `Bash(ls) x`), which never matched anything, to be reported as invalid settings instead of being silently ignored
- Changed server-managed settings so a managed CLAUDE.md (`claudeMd`) no longer triggers the security approval dialog; hooks, shell-command, sandbox, and unsafe `env` settings still require approval
- Changed Claude in Chrome to follow your organization's Claude in Chrome admin setting; when an admin turns it off, `--chrome`, `/chrome` and the browser tools are unavailable
- Changed Claude apps gateway to send `orgPluginSettings` in the list form read by Claude Desktop 1.15200.0 and later; older desktops ignore it
- Changed Claude apps gateway to also refuse to start, naming the field, when a `desktop` policy misspells a field in a nested object of a `managedMcpServers` or `orgPluginSettings` entry
- Changed commands typed at the `!` bash-mode prompt to run outside the sandbox even when strict sandbox mode (`sandbox.allowUnsandboxedCommands: false`) is on, like typing into your own terminal
- Changed self-hosted runner `--kill-session-after-min` to release a session that is only waiting on its user (paused, resumable on the next message) instead of killing it and reporting a failure
- Removed the one-hour time limit on background commands started by subagents; they now run until they exit or are stopped, matching the main session
- [VSCode] Added the selected effort level to the footer model pill, fixed a stale effort level after switching models, and returned the footer pills to their earlier compact size
- [VSCode] Added Open and Closed to the session list's status filter menu
- [VSCode] Fixed the welcome screen disappearing in a new session when Remote Control turns on automatically
- [VSCode] Fixed the session history picker loading a session a second time when it is already open in another tab; it now switches to that tab
- [VSCode] Fixed the session tab's Rename command silently doing nothing while the tab's view was reloading; it now always applies
- [VSCode] Fixed a half-finished message, an empty tool card or an extra "Thought for" line staying on screen after Claude Code retried a dropped response
- [VSCode] Fixed "Enable Remote Control for all sessions" not applying to a session tab that was still starting when the toggle was flipped

- Added `managedMcpServers` managed setting: organizations can provide HTTP/SSE MCP servers to every user (same entry shape as `.mcp.json`); entries that name a command to run are skipped
- Added `--permission-prompts none` for unattended headless hosts: anything that would prompt is denied automatically while the active permission mode (including auto mode) keeps deciding
- Added recognition of `glab mr create/merge/close/reopen/note/update` so GitLab merge requests show as `MR !N` in the collapsed tool summary and refresh the footer MR badge
- Added `--json` to `claude plugin validate` for a machine-readable validation report
- Fixed concurrent sessions silently reverting each other's `~/.claude.json` changes — workspace trust no longer resets and MCP/project state is no longer lost when running many sessions at once
- Fixed a conversation whose thinking was rejected once being rejected again on every later turn
- Fixed Bash `Read()` deny rules not covering files given as option values (`--ignore-revs-file=.env`, `-f.env`, `@file`), `git diff`/`git grep` file operands, or `cd DIR && cat FILE` compounds; `grep -r`/`cp -r` over a directory holding a denied file now asks
- Fixed the prompt cache being invalidated when the OAuth token refreshed in sessions with telemetry disabled
- Fixed fullscreen mode showing a blank conversation after a long turn with hundreds of tool calls
- Fixed auto mode running a turn on a model it doesn't support when a command or skill's frontmatter `model:` named one; the turn now keeps the session model
- Fixed `CLAUDE_CODE_MAX_CONTEXT_TOKENS` being ignored for Vertex-style model IDs (`@YYYYMMDD` suffix) of model versions Claude Code doesn't recognize
- Fixed the live output preview of a running shell command hiding its newest lines when an earlier line wrapped
- Fixed a background GitHub connection check that ran on every launch for claude.ai users; the result is now remembered across launches
- Fixed `--resume` failing (and `--continue` opening an empty conversation) when a saved session contains an attachment entry with no payload
- Fixed frontmatter `model:` on custom commands and skills being ignored in interactive sessions
- Fixed Artifact publishing failing once with an "unexpected parameter `note`" error in conversations continued from an older version
- Fixed managed `forceRemoteSettingsRefresh` being ignored at startup when a policy helper configured by MDM or the managed settings file had already run
- Fixed worktree isolation refusing hook-created worktrees on machines where `git rev-parse` fails with a message other than "not a git repository"
- Fixed OpenTelemetry metrics and events from cloud sessions missing the `user.email`, `organization.id`, and `user.account_uuid` attributes
- Fixed MCP servers that disconnect while their tools are being listed at startup showing as connected with no tools instead of reporting the error
- Fixed the file edit permission dialog sometimes showing a changed line cut short with no indication
- Fixed repository detection dropping a known repo identity after a transient git probe failure
- Fixed managed settings silently going unenforced when the managed-settings file, a drop-in, the MDM plist, or the HKLM value cannot be parsed: Claude Code now refuses to start and names the source
- Fixed Stop not actually stopping background agents and workflows in remote-control sessions: killed tasks now stay visible and re-stoppable until their processes exit
- Fixed resuming a workflow run while its previous stopped run was still exiting, which could run duplicate copies of its agents
- Fixed marketplace repo URLs on github.com with a trailing slash or dangling `?`/`#` producing an unusable `.git` clone URL
- Fixed blocking Stop hooks causing the turn after a block to lose the model's reasoning from that turn and, on some models, miss the prompt cache
- Fixed remote (claude.ai) sessions taking 60 seconds to start a turn after a browser-hosted MCP server's page had gone away
- Fixed worktree-isolated sessions refusing common Bash loops, xargs pipelines and launcher-wrapped commands that cannot reach the main checkout
- Improved terminal resize and first-render performance for long responses by reusing text measurements
- Improved `/workflows` agent detail: JSON outcomes are pretty-printed with syntax colors and real line breaks, and long outcomes fold behind an expand toggle
- Improved headless/SDK session start: the first turn begins up to 50 ms sooner when MCP servers finish connecting
- Improved `/install-github-app` to explain it is GitHub-only and point to the GitLab CI/CD docs when run inside a GitLab repository
- Improved nested background subagent results to be saved in the parent subagent's transcript, so resumed subagents keep them and shared transcripts show the delivery
- Changed `allowedMcpServers` to govern only servers users add: a literal `managed-mcp.json` server your allowlist used to filter out now loads on upgrade; use `deniedMcpServers` to keep it off
- [VSCode] Added an Active quick filter and a status filter menu (Needs input, Working, Completed) to the session list sidebar
- Fixed remote and scheduled sessions doing nothing after a connector-tool permission prompt was approved while the session was paused

- Fixed Claude Code failing to launch on macOS 12 (Monterey), a regression introduced in 2.1.255
- Fixed remote and scheduled sessions failing with "user messages must have non-empty content" after a re-sent permission approval could not be applied

- Added Claude Fable 5.1 (`claude-fable-5-1`), now the default Fable model — 1M context, $10/$50 per Mtok with $0.25/Mtok cache reads
- Added "Time format" (`timeFormat`) and `timeZone` settings: 12-hour, 24-hour, 24-hour UTC, or a strftime pattern for the turn-end clock and transcript-view timestamps
- Added a Containment Escape rule to auto mode so cloud metadata-credential fetches, egress evasion, and cross-tenant reach are no longer auto-approved unless your environment marks them expected
- Added `CLAUDE_CODE_SUBAGENT_MODEL_FORCE` to apply `CLAUDE_CODE_SUBAGENT_MODEL` (or the main model) to every subagent, ignoring per-spawn and agent-definition model overrides
- Added `s` in `/effort` to change effort for the current session only, matching `/model`
- Added a `/doctor` warning for stale sandbox mask files left by a killed session
- Added a one-time prompt in auto mode before the first file read outside the working directories, with the option to block such reads (`permissions.blockReadsOutsideWorkingDirectories`)
- Added support for a gateway-supplied `description` on discovered `/model` picker entries (`CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY`); entries without one still read "From gateway"
- Fixed settings in a `.claude/` folder created after startup not being picked up until restart
- Fixed sessions dispatched from an agent view opened with `←` always starting in the original session's permission mode, overriding the target directory's `defaultMode` and the agent's `permissionMode`
- Fixed `keybindings.json` rebinds of Ctrl+G being ignored in `claude agents`; its Ctrl+S / Ctrl+T are now rebindable via the new `Agents` context
- Fixed background sessions failing to start on macOS npm installs during a self-update, and on Windows when a stale daemon lock file pointed at a reused process id
- Fixed the working spinner stopping while a response streams behind a slash-command panel
- Fixed a background session's `state.json` `detail` repeating its own dispatch prompt after a scheduled wake-up
- Fixed `claude agents` keeping a background session you re-prompted buried in Completed after it finished again; Completed now orders by the latest finish
- Fixed `claude --bg` from a directory that was just deleted reporting "backgrounded" and leaving a crashed session row; it now prints the reason and exits 1
- Fixed Remote Control connecting mid-session re-sending the Bash tool definition, causing a prompt-cache miss
- Fixed a doubly-listed custom `Authorization` header overriding the configured credential on Bedrock, Mantle, Vertex, and WIF, and the Vertex setup wizard picking up a leftover Anthropic profile from `~/.config/anthropic`
- Fixed Claude apps gateway sending stray host `Authorization` or profile headers to Foundry, Vertex, and Bedrock, and Foundry Entra ID upstreams not starting when `ANTHROPIC_FOUNDRY_API_KEY` is set
- Fixed a leftover Anthropic API key or auth token being sent alongside your Foundry subscription key in API-key mode
- Fixed `/schedule` routines whose prompt was saved without a message role and then ran with nothing to do
- Fixed `claude agents` not saying that a background session is waiting for you to approve a message from another session, or who sent it
- Fixed a prompt stashed with Ctrl+S inside an opened background session being lost when the session went idle or was stopped and then reopened
- Fixed telemetry (OTEL) settings pushed through server-managed settings being ignored on warm starts, including desktop-app Code sessions
- Fixed a teammate permission request being answered twice when the leader's mailbox write was briefly locked
- Fixed a phantom duplicate slash-command row rendering below the in-flight turn while a command's auto-continued response streamed
- Fixed `policyHelper` `timeoutMs` and `refreshIntervalMs` values above the timer maximum (2147483647) causing failures or re-runs every millisecond; they are now clamped
- Fixed the token counter freezing or crawling after switching to another subagent's transcript, and made background subagents' and teammates' counters update live while a response streams
- Fixed sandbox network hosts written with a trailing dot (`example.com.`): a `deniedDomains` entry didn't block the host inside the sandbox, and "don't ask again" for such a host kept prompting
- Fixed dismissing the Remote Control consent prompt (Esc, or `n` at `claude remote-control`) counting as consent, so the next request connected without asking
- Fixed `/mcp` reconnect and enable still connecting a settings-file MCP server that a managed MCP allow/deny list or `strictPluginOnlyCustomization` loaded after startup should block
- Fixed `claude mcp remove` leaving a remote server's stored OAuth credentials behind when `strictPluginOnlyCustomization` locks MCP to plugin-only servers
- Fixed Remote Control (`claude remote-control`) sessions started from the Claude app ignoring the selected model and running on the machine's default instead
- Fixed `--disallowedTools` and session deny rules being dropped after the first settings reload when `allowManagedPermissionRulesOnly` is enabled
- Fixed `--resume` listing a backgrounded conversation twice and `--continue` reopening its stalled pre-background copy; `--continue` now also opens finished background sessions
- Fixed fullscreen mode not letting you click `!` shell command output to expand it
- Fixed background sessions left running an older Claude Code binary piling up across auto-updates instead of being retired
- Fixed `claude agents --json` briefly switching the terminal to raw mode and undoing another program's terminal settings on exit
- Fixed Proactive output style sessions busy-looping with filler messages and repeated log reads instead of idling while a background command or Monitor they started is still running
- Fixed subagents stopping when a response was cut off mid-stream by a computer sleep, dropped connection, or server error; they now automatically continue instead of ending with an incomplete response
- Fixed `←` doing nothing in the `/btw` panel inside a `claude agents` session: it now returns to the agents list (even mid-answer), and the panel comes back when you reopen the session
- Fixed sessions with an advisor model set missing the prompt cache on background requests (compaction, `/recap`, prompt suggestions) and re-sending the full conversation uncached each time
- Fixed `claude -p` exiting about 5 seconds after its final result while a Monitor the model armed was still running; it now waits for the watch to fire or time out
- Fixed a `permissions.ask` rule being skipped in auto mode when the matching command ran inside a compound command or subshell, letting it run without the confirmation prompt
- Fixed plugins being able to read files outside their own directory through a declared command, agent, skill, hooks or other component path that is a symlink; such paths are now refused with an error
- Fixed `/add-dir` rejecting a directory inside the current working directory; it now loads that directory's skills, commands, and agents like `--add-dir` does at startup
- Fixed the main agent not being told when you resume a subagent you had stopped from its transcript view
- Fixed a crash when pasting ANSI-colored text (e.g. a CI log) into dialogs like `/feedback`
- Fixed `claude mcp add/remove` hanging or exhausting memory when the project's `.mcp.json` is a FIFO or a device-file symlink; it now fails fast with an actionable message
- Fixed unbounded memory growth when non-JSONL data is piped into `claude -p --input-format stream-json`; it now fails fast with a clear error
- Fixed backgrounding a turn (`←` or Ctrl+B) while a subagent or other tool was running occasionally making the background session treat that tool as rejected instead of re-running it
- Fixed Bash `Read()`/`Edit()` deny rules not applying to `< file` redirects and reader commands like `tac` and `egrep`; a deny rule on any argument or redirect target now refuses the command
- Fixed resuming or messaging a subagent whose transcript had grown past 5 MB (for example after reading many images) failing with "No transcript found"
- Fixed worktree-isolated sessions refusing Bash loops, `$VAR` reads, `"$(…)"` and heredocs that never touch git as "too complex to verify that it stays inside the worktree"
- Fixed `/model` and `/effort` showing a prompt-cache warning after rewinding a conversation back to empty
- Fixed prompt-cache misses on every turn in long screenshot-heavy sessions once images exceeded the per-request size cap
- Fixed the Edit permission prompt's diff view rendering emoji and multi-code-point characters with incorrect widths
- Fixed WebSocket MCP server connection failures being logged as "[object ErrorEvent]" instead of the underlying error
- Fixed background sessions failing to open with "Couldn't start the background service" while another Claude Code process was downloading an npm update; the start now waits for it
- Fixed background commands that detach from their shell (for example under `timeout` or `setsid`) surviving a task stop or Claude Code exit
- Fixed Claude not being told when you stop a background command from the tasks panel or a connected client
- Fixed stopping a background subagent leaving its monitors running
- Fixed sandboxed git commands in a linked worktree losing write access to the repository's common `.git` directory after `cd` into a subdirectory
- Fixed Bedrock and Bedrock Mantle requests going silent during long hidden-thinking phases on Opus 4.7 and later, which let idle timeouts cut the connection; the stream now carries progress events
- Fixed launching Claude Code after a Claude apps gateway expired or revoked your session: it now says the session ended and offers `/login` instead of reporting a network error
- Fixed cloud sessions losing git/GitHub credentials for the rest of the session when the session's network proxy failed to start at launch; it now retries in the background and recovers
- Fixed leftover `cc-daemon-*` folders in the system temp directory after an interrupted background daemon start; the `cleanupPeriodDays` retention sweep now removes them
- Fixed Bash permission checks auto-approving certain `[[ ]]` conditionals that zsh parses differently from bash; these commands now prompt for approval
- Fixed the managed-settings approval prompt showing the generic warning instead of its telemetry wording when the settings also turn detailed tracing or raw API body logging off, or trace export on
- Fixed agent-team teammates in tmux/iTerm2 panes sometimes staying open after acknowledging a shutdown request
- Fixed the keyless Console sign-in ("Sign in with your Console account") not applying your organization's server-managed settings, and `/status` not showing the Organization for that sign-in
- Improved rendering performance: less re-render work per turn in long conversations, streaming no longer slows down as the reply grows, and background-agent updates no longer re-render the whole screen
- Improved prompt input responsiveness by reducing per-keystroke rendering work
- Improved policy helper diagnostics — refresh failures now show in `/status`, declining the managed-settings dialog prints why Claude Code exited, and helper timeouts are reported as timeouts
- Improved `/code-review --comment` to post findings on GitLab merge requests via `glab mr note` instead of reporting the target as unsupported
- Improved notifications: an MCP elicitation or permission ask queued under another dialog now sends its idle desktop notification at the same delay as a visible ask
- Improved verbose/transcript output: async hook completion notices that arrive together now appear on one line instead of one line per hook
- Improved `claude self-hosted-runner --configure-git` to also enable git push negotiation, so the first push of a new branch from a stale clone uploads only the new commits instead of the whole tree
- Improved liveness reporting to SD

these notes continue in the original release.
