Claude Code CLI 2.1.308 changelog: Other change: • Bug fixes and reliability improvements Source: github.com/anthropics/claude…

Claude Code 2.1.307 system prompt updates Notable changes: 1) Claude’s tool-hook guidance is cleaned up: the Harness bullet now ends after “treat hook output as user feedback” instead of the malformed “feedback.Response”. This reduces ambiguity/noise in how Claude interprets hook output during tool use. Links: 1) github.com/marckrenn/claude-…

Claude Code CLI 2.1.306 changelog: Fixes: • Fixed claude -p inside cloud sessions reporting "Not logged in" when started without the session's environment variables • Fixed an API error being replaced by "prompt is too long", and an unneeded compaction, in sessions with many MCP tools Source: github.com/anthropics/claude…

Claude Code CLI 2.1.305 changelog: New features: • Added sandbox.allowNestedUserNamespaces so sandboxed commands on Linux can create user namespaces (Chromium, rootless podman); this lets them get around the sandbox's file protections • Added CLAUDE_CODE_RETRY_WATCHDOG_USAGE_LIMIT_RECHECK_MS so unattended retry mode (CLAUDE_CODE_RETRY_WATCHDOG) notices a usage limit that was lifted before its reset Fixes: • Fixed every request failing on Vertex, Bedrock and other providers when the endpoint or a gateway rejects tool search, and behind gateways with ToolSearch disallowed or left out of --tools (a 2.1.304 regression): Claude Code now retries without it • Fixed /effort and /autocompact settings not applying when the model name differed from a modelOverrides value by letter case or a [1m] tag • Fixed new worktrees in a bare repository sometimes starting from local HEAD instead of the default branch, and unchanged subagent worktrees sometimes not being cleaned up • Fixed Bash commands on a full disk failing with a raw ENOSPC file path: the error now says the disk is full and that nothing ran • Fixed an MCP server passed by a cloud session or by the SDK's setMcpServers being replaced later in the session by a same-named server from your own settings • Fixed Claude naming the wrong model for a subagent's work after the subagent switched to a fallback model • Fixed cloud sessions and teammates not telling Claude when a compaction had to leave the oldest messages out of its summary to fit • Fixed more cases of scheduled Cowork cloud sessions waiting five minutes for each subagent whose WebFetch needed a URL approval that nobody was there to give • Fixed Workflow resume re-running already-completed pipeline() and parallel() agents instead of serving them from the run's journal • Fixed Remote Control leaving empty "(session)" entries in /resume after switching conversations with /resume • Fixed /usage rows being cut off in narrow terminals • Fixed startup warnings printing as raw text above the logo: they now go to the debug log, and permission rules that restrict nothing show as warning rows under the banner • Fixed screen reader mode: search boxes now say "Search:" instead of a symbol VoiceOver read as "telephone recorder", and highlighted prompt text, such as Ctrl+R search matches and "ultrathink", no longer has spaces inside words • Self-hosted runner: Fixed a start script that shares only its stdout with the runner or orchestrator failing with Resource temporarily unavailable when TERM is set (a 2.1.300 regression) Improvements: • Improved /usage: each warning is now a one-line fix that names its source, and f applies the fixes; the same fixes appear in VS Code and /doctor • Improved MCP consent dialogs so an Enter meant for the prompt is less likely to be taken as Accept • Improved a mod's Image to draw its picture in iTerm2 3.5 and later with fullscreen rendering, where it showed only its alt text Security/safety change: • Changed plugins that Claude Desktop mounts by path to no longer keep their allowed-tools when your organization's managed settings set allowManagedPermissionRulesOnly Other changes: • Self-hosted runner: Fixed repository access failing since 2.1.296 when a git credential helper or askpass program reads its settings through GIT_CONFIG • Self-hosted runner: Fixed the orchestrator reporting a spawn-runner hook as timed out when a runner it started in the background kept its output open • Remote Control: Improved the spawn-mode messages: pressing w now says the new mode is saved for the folder, and a later claude remote-control start that uses the saved mode says where it came from • Changed allowedMcpServers to stop filtering managed-mcp.json stdio servers that use ＄{VAR} only in env: one your allowlist left out now loads on upgrade; use deniedMcpServers to keep it off • Changed the /artifacts delete confirmation to take 1 or Enter to keep, 2 to delete, and Esc to cancel; y and n no longer answer it • Changed a mod's docked pane to stay within 45% of the terminal's width, including a width kept from a wider terminal • [VSCode] Added a "Running start-up hooks" spinner status, with a screen reader announcement, while SessionStart or Setup hooks run • [VSCode] Fixed the spinner cutting off "Compacting..." when your spinnerVerbs setting replaces the built-in verbs with short ones • [VSCode] Changed the message shown when a session does not start in time and no hook is running: it now leads with the output logs and lists causes instead of pointing to sign-in and network first • [Cloud sessions] Fixed the Cloud environments admin page wrongly refusing to save an existing environment with an "installs packages" error • [Cloud sessions] Improved deleting a self-hosted environment so the dialog and error messages say what blocks the delete and what it will affect • [Claude Tag] Added public Slack channels Claude hasn't joined to the Claude Tag admin Add place search, so admins can set one up from there • [Claude Tag] Fixed Claude Tag access bundles so a repository that moved to another GitHub account can be added again • [Claude Tag] Fixed a routine set up in a Slack DM thread no longer posting after another routine in that thread restarted the conversation; both now keep posting there • [Claude Tag] Fixed routines set up in a Slack thread reporting success without posting after the conversation ended; those runs are now skipped and the creator is told • [Claude Tag] Improved Claude Tag admin pages in large organizations so plugin, skill and bundle edits work while the channel list is still loading • [Code Review] Fixed Code Review sometimes not reviewing the newest commit when several pushes landed on a pull request during a review • [Code Review] Changed Code Review re-reviews so they no longer open with LGTM while earlier blocking findings are still open Source: github.com/anthropics/claude…

Claude Code CLI 2.1.304 changelog: New features: • 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 Fixes: • Fixed the organization policy not refreshing until the hourly check after approving an ANTHROPIC_API_KEY at startup or switching "Use custom API key" in /config • Fixed sandboxed commands failing to start on Linux when a sandbox.filesystem.denyRead glob contains brackets that are not a character class, such as a [user-id] route folder • Fixed rm -r of a mounted drive or a folder at its top level (/Volumes, /media, WSL's /mnt/c) not getting the safety prompt that rm -rf /Applications gets • Fixed CLAUDE_CODE_TRANSCRIPT_LOCAL_GC dropping messages from the saved transcript when the disk filled up while the file was being trimmed • Fixed a plugin keeping a headless run going past --max-turns, Stop, or ended input by spawning subagents or re-running a finished one • Fixed a failed mod reload removing the tools and commands of the version that stays loaded, and its messages being wrong or silent about whether the previous version is still loaded • Fixed a click on a mod's button being lost when buttons with the same label and no key were redrawn unchanged • Fixed mod sharing in the built-in plugin-authoring skill stopping at the secret scan on machines with managed settings and on Team and Enterprise plans • Fixed scheduled Cowork cloud sessions waiting five minutes again for each subagent whose WebFetch needed a URL approval that nobody was there to give • Fixed Write results and rejected edits showing a file outside the working directory as ../../…; they now show ~/… or the full path • Fixed a claude.ai Directory plugin's skills not running as commands when picked from the "/" menu in Cowork cloud sessions • Fixed Remote Control permanently withholding a desktop conversation's history when a different account was signed in to the terminal • Fixed Remote Control failing to start from Claude Desktop when DISABLE_TELEMETRY or DO_NOT_TRACK is set on a paid plan • Fixed model switches, messages and interrupts waiting behind a context usage check in SDK and desktop sessions • Fixed context_management: Extra inputs are not permitted errors behind LLM gateways; Claude Code now resends the request without that field • Fixed OpenTelemetry settings delivered through server-managed settings being ignored for the whole session after signing in during first-run setup or the first start after /logout • Fixed unsandboxed Bash commands in Claude Desktop Code tab sessions on macOS and Linux not seeing environment variables exported in shell startup files such as ~/.zshrc • Fixed the Consumer Terms notice being skipped for a day or longer after a server error • Fixed /privacy-settings offering choices that may not apply to you after a network or server error • Fixed a "Context limit reached" or "Prompt is too long" error after stopping a turn while Claude Code was compacting a conversation the API had rejected as too long • Fixed subagents sometimes forgetting their most recent work when they were messaged or resumed right after finishing • Fixed claude --help text for --tools, --resume, --debug, --json-schema, --disable-slash-commands, --system-prompt-snapshot and claude update to match actual behavior • Fixed claude --worktree removing the worktree and its branch without asking at exit when HEAD was detached or on another branch, which could lose commits • Fixed resumed and cloud sessions sending Claude the whole skill list again each time plugins reloaded at startup • Fixed an interrupt not ending a Read that waits on an idle pipe or device named like an image • Fixed /effort status, /effort ultracode and the prompt's effort indicator showing a guessed effort level when CLAUDE_CODE_EFFORT_LEVEL is auto or unset and no level is sent • Fixed a PreToolUse hook's deny reason being replaced by a timeout error when an Agent SDK callback hook on the same tool call timed out • Fixed Bash and PowerShell deleting a large command's output file when it could not be copied to the session's tool-results folder, unless the disk is full • Fixed notes typed into a multiple-choice question with previews being cut off with "…" in terminals under about 100 columns, hiding what was typed (anthropics/claude-code#82768) • Fixed self-paced /loop wakeups scheduled at the 1-hour maximum firing just after the 1-hour prompt cache expired, so those wakeups no longer re-read the conversation uncached • Fixed agent teams: approving a shutdown request from the main session no longer exits the whole CLI • Fixed a skill's once hook also removing another skill's identical hook after it ran • Fixed transcript mode's { and } landing the prompt on an inconsistent row, or off screen, instead of the transcript's first row • Fixed CLAUDE_CODE_AUTO_COMPACT_WINDOW=200k silently setting a 100K window: the variable now accepts k and M suffixes like --autocompact, and warns when a value is out of range or ignored • Fixed Ctrl+C in the agents view clearing a text selection without copying it when pressed before the mouse button was released Improvements: • Improved /usage to say when a rate limit on usage data ends instead of "try again in a moment" • Improved the lines shown when a mod written in the session loads, reloads or fails to load • Improved artifacts with several views: when you ask for links to them, Claude now writes out each view's link and explains that the address bar stays the same as you switch views • Improved cloud sessions: a new conversation's first turn no longer waits for the local (stdio) MCP servers of plugins synced from claude.ai, unless a server sets alwaysLoad: true • Improved how a remote session recovers its status when the server refuses a status update that carried other session data • Improved session file size in auto mode: the safety classifier's context is no longer stored with every request • Improved the claude -p invalid-settings warning: a file that did not load lists only what stopped it, and long lists are capped per file • Improved resume of large compacted sessions in SDK and headless mode: the first request after resuming is sent sooner • Improved responsiveness and throughput when many subagents are running at the same time • Improved memory use when sending requests in long or resumed conversations • 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 Removals: • 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 Other changes: • 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 • 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 • [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 Source: github.com/anthropics/claude…
