最新更新

2.1.261

  • 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

2.1.260

  • 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

2.1.259

  • 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
