What's changed

• Added a transcript line when a plugin that runs first skips one of your mod's hooks, naming the event and the plugin
• Added decider: "person" to a mod's tool.check answer: only the permission dialog or a host's callback can approve the ask, and it is refused with the mod's reason where nobody can be asked
• Added e.isReadOnly to a mod's tool.check event, set when the tool call is read-only
• Added /auto-mode-setup: a guided setup that reads your project and recent sessions to teach auto mode about your environment, now also available on Bedrock, Vertex, Foundry, Claude apps gateway and telemetry-disabled sessions
• Added /claude-api managed-agents-secure, which compares a Managed Agents agent's settings with Anthropic's published security guide, without changing anything
• Added the names of the tools called earlier to the compaction summary in the transcript view (Ctrl+O)
• Added a warning on Pro and Max plans when resuming an inactive conversation would use a noticeable share of your 5-hour usage limit: resume anyway, or start a new conversation and Claude can look up the previous one if you refer to it
• Fixed the organization policy not refreshing until the hourly check after approving an ANTHROPIC_API_KEY at startup or switching "Use custom API key" in /config
• Fixed sandboxed commands failing to start on Linux when a sandbox.filesystem.denyRead glob contains brackets that are not a character class, such as a [user-id] route folder
• Fixed rm -r of a mounted drive or a folder at its top level (/Volumes, /media, WSL's /mnt/c) not getting the safety prompt that rm -rf /Applications gets
• Fixed CLAUDE_CODE_TRANSCRIPT_LOCAL_GC dropping messages from the saved transcript when the disk filled up while the file was being trimmed
• Fixed a plugin keeping a headless run going past --max-turns, Stop, or ended input by spawning subagents or re-running a finished one
• Fixed a failed mod reload removing the tools and commands of the version that stays loaded, and its messages being wrong or silent about whether the previous version is still loaded
• Fixed a click on a mod's button being lost when buttons with the same label and no key were redrawn unchanged
• Fixed mod sharing in the built-in plugin-authoring skill stopping at the secret scan on machines with managed settings and on Team and Enterprise plans
• Fixed scheduled Cowork cloud sessions waiting five minutes again for each subagent whose WebFetch needed a URL approval that nobody was there to give
• Fixed Write results and rejected edits showing a file outside the working directory as ../../…; they now show ~/… or the full path
• Fixed a claude.ai Directory plugin's skills not running as commands when picked from the "/" menu in Cowork cloud sessions
• Fixed Remote Control permanently withholding a desktop conversation's history when a different account was signed in to the terminal
• Fixed Remote Control failing to start from Claude Desktop when DISABLE_TELEMETRY or DO_NOT_TRACK is set on a paid plan
• Fixed model switches, messages and interrupts waiting behind a context usage check in SDK and desktop sessions
• Fixed context_management: Extra inputs are not permitted errors behind LLM gateways; Claude Code now resends the request without that field
• Fixed OpenTelemetry settings delivered through server-managed settings being ignored for the whole session after signing in during first-run setup or the first start after /logout
• Fixed unsandboxed Bash commands in Claude Desktop Code tab sessions on macOS and Linux not seeing environment variables exported in shell startup files such as ~/.zshrc
• Fixed the Consumer Terms notice being skipped for a day or longer after a server error
• Fixed /privacy-settings offering choices that may not apply to you after a network or server error
• Fixed a "Context limit reached" or "Prompt is too long" error after stopping a turn while Claude Code was compacting a conversation the API had rejected as too long
• Fixed subagents sometimes forgetting their most recent work when they were messaged or resumed right after finishing
• Fixed claude --help text for --tools, --resume, --debug, --json-schema, --disable-slash-commands, --system-prompt-snapshot and claude update to match actual behavior
• Fixed claude --worktree removing the worktree and its branch without asking at exit when HEAD was detached or on another branch, which could lose commits
• Fixed resumed and cloud sessions sending Claude the whole skill list again each time plugins reloaded at startup
• Fixed an interrupt not ending a Read that waits on an idle pipe or device named like an image
• Fixed /effort status, /effort ultracode and the prompt's effort indicator showing a guessed effort level when CLAUDE_CODE_EFFORT_LEVEL is auto or unset and no level is sent
• Fixed a PreToolUse hook's deny reason being replaced by a timeout error when an Agent SDK callback hook on the same tool call timed out
• Fixed Bash and PowerShell deleting a large command's output file when it could not be copied to the session's tool-results folder, unless the disk is full
• Fixed notes typed into a multiple-choice question with previews being cut off with "…" in terminals under about 100 columns, hiding what was typed (#82768)
• Fixed self-paced /loop wakeups scheduled at the 1-hour maximum firing just after the 1-hour prompt cache expired, so those wakeups no longer re-read the conversation uncached
• Fixed agent teams: approving a shutdown request from the main session no longer exits the whole CLI
• Fixed a skill's once hook also removing another skill's identical hook after it ran
• Fixed transcript mode's { and } landing the prompt on an inconsistent row, or off screen, instead of the transcript's first row
• Fixed CLAUDE_CODE_AUTO_COMPACT_WINDOW=200k silently setting a 100K window: the variable now accepts k and M suffixes like --autocompact, and warns when a value is out of range or ignored
• Fixed Ctrl+C in the agents view clearing a text selection without copying it when pressed before the mouse button was released
• Improved /usage to say when a rate limit on usage data ends instead of "try again in a moment"
• Improved the lines shown when a mod written in the session loads, reloads or fails to load
• Improved artifacts with several views: when you ask for links to them, Claude now writes out each view's link and explains that the address bar stays the same as you switch views
• Improved cloud sessions: a new conversation's first turn no longer waits for the local (stdio) MCP servers of plugins synced from claude.ai, unless a server sets alwaysLoad: true
• Improved how a remote session recovers its status when the server refuses a status update that carried other session data
• Improved session file size in auto mode: the safety classifier's context is no longer stored with every request
• Improved the claude -p invalid-settings warning: a file that did not load lists only what stopped it, and long lists are capped per file
• Improved resume of large compacted sessions in SDK and headless mode: the first request after resuming is sent sooner
• Improved responsiveness and throughput when many subagents are running at the same time
• Improved memory use when sending requests in long or resumed conversations
• Self-hosted runner: Improved the error shown when the git host answers "not found" for a session's repository: it now names the repository and whom to ask
• Windows: Improved git command start-up with a standard Git for Windows install by running its git.exe directly instead of through its cmd launcher
• Changed mods' settings.read hooks to receive each settings layer and rewrite the merged settings, so a managed mod can make an organization's setting a ceiling, including the cleanupPeriodDays the retention sweep uses
• Changed the /artifacts delete confirmation to show numbered choices: 1 or Enter keeps the artifact, 2 deletes it, and y, n and Esc still work
• Changed the question that turns on the mods Claude writes in a session to plain text with no link or session id; it stays up when a new turn starts, and Claude tells you what loaded when you turn them on
• Changed tool search to be on by default behind a custom ANTHROPIC_BASE_URL; a 400 or 422 from the gateway is retried without it
• Changed compaction to send Claude the skill list again afterwards; /reload-skills now sends only new or changed skills
• Changed skill hooks: the skills of one source (a repo, your own folder, or a plugin) can register at most 1,024 hooks and 16,384 matcher characters per session
• Changed skills under a policy that allows hooks from plugins only: a skill used in the main conversation whose hooks are kept out no longer gets its allowed-tools
• Updated the /claude-api skill to use the ant CLI on Claude Platform on AWS instead of falling back to the SDK or curl
• Removed the notes from claude plugin validate that predicted where a mod's hooks would run
• Removed the "(research preview)" label from the /fast dialog title on Opus 5.5
• [VSCode] Added mod drawing in the chat panel for sessions on Amazon Bedrock, Google Vertex AI and Microsoft Foundry, behind an LLM gateway, or with telemetry turned off
• [VSCode] Fixed one cause of sessions failing to start with "Subprocess initialization did not complete within 60000ms": time a SessionStart command hook spends running no longer counts toward the limit, up to 10 minutes in total
• [VSCode] Fixed a session closed while it was starting keeping its Claude Code process running until the start ended
• [VSCode] Fixed a mod's drawings disappearing from a long-open panel until the next turn on machines that also run an older Claude Code
• [VSCode] Fixed Past conversations hiding sessions when claudeCode.claudeProcessWrapper is set
• [VSCode] Changed background sub-agents to show as one status line under their Agent card instead of streaming every step into the chat; the full transcript stays in /tasks
• [Cloud sessions] Fixed folders in the composer's @ list showing no name in cloud sessions, where picking one added only a space instead of a mention
• [Claude Tag] Fixed Claude going silent in a thread when its channel becomes shared across Enterprise Grid workspaces mid-task; it now posts a one-time note to @-mention it in a new thread
• [Claude Tag] Fixed @Claude !fork typed outside a thread getting no visible reply; Claude now shows you a private note saying to run it from inside a thread
• [Code Review] Added review levels to Code Review: Owners choose Quick, Standard (the default), or Deep for the organization, and can give individual repositories their own level
• [Code Review] Added an option in Code Review admin settings to review every repository in a GitHub organization, including ones added later, without selecting them one by one
• [Code Review] Fixed pull requests opened within a minute or two of an admin turning on Code Review being silently skipped; they are now retried and reviewed
