Claude Code v2.1.309 发布：修复 macOS/Linux 沙箱与多项权限问题

What's changed

• Fixed sandboxed Bash commands on macOS and Linux running the shell's startup files outside the sandbox before each command
• Fixed macOS sandbox denyWrite glob patterns not applying at a path's real location when the pattern's folder is reached through a symlink
• Fixed sandboxed commands and auto-accepted edits being able to modify the MCP config file passed with --mcp-config
• Fixed a disabled MCP server being reconnected by a later permission prompt in print and SDK sessions
• Fixed the Bash permission check trusting a variable set by a command whose redirect can fail to open
• Fixed Bash permission checks not prompting for some compound commands that change directory before running git when the cd is wrapped or prefixed, as they do for a plain cd
• Fixed an Edit(path) deny rule not blocking a Bash redirect to that path in some commands that also held a subshell
• Fixed worktree-isolated sessions accepting some locale-prefixed commands the isolation guard should refuse
• Fixed worktree-isolated sessions on zsh accepting some arithmetic commands that the isolation guard should refuse
• Fixed worktrees and branch checkouts that Claude Code creates so they ignore git replace refs, as its other git operations already do
• Fixed profile store write protection not applying when the config directory is reached through a symlink
• Fixed sessions compacting repeatedly after reading files under a very large nested CLAUDE.md; a nested CLAUDE.md over the size limit now loads only its start
• Fixed ctrl+enter (send now) only queuing a message when pressed before the response had started, and restarting a prompt's hooks while leaving the message queued when pressed while those hooks were running
• Fixed key-bound slash commands running in the shell from ! mode
• Fixed ctrl+o not showing messages from other agents and sessions that are still waiting to be delivered; they now appear in full under the transcript, marked as waiting
• Fixed long tool output previews being cut through an emoji, leaving session transcripts that jq could not parse
• Fixed Read reporting "File does not exist" for PDF page ranges in Linux sandboxes that share the parent's /proc
• Fixed messages from a Claude Desktop-hosted session sometimes being lost when its connection refreshed
• Fixed features missing from Claude Code sessions in the Claude desktop app when the terminal on the same computer was signed in to a different account or organization
• Fixed the claude remote-control status line showing HEAD as the branch for a folder that is not in a git repository
• Fixed split-pane agent teammates not inheriting the tool deny and --tools rules given on the leader's command line
• Fixed sessions renamed with /rename appearing to other sessions under a generated name after a VS Code window reload or a non-interactive --resume
• Fixed the /rewind list showing "No code changes" for a turn that changed checkpointed files through /code-review --fix, a subagent or a shell command
• Fixed /privacy-settings showing an out-of-date "Help improve our AI models" value; it now also says when the setting can't be fetched
• Fixed feedback saying "try again later" when your organization does not accept feedback; it now shows the server's reason and where to report a bug
• Fixed oversized /feedback reports failing instead of being resent without the transcript
• Fixed a skill in an --add-dir folder being unreachable when another skill already held its name; it is now offered as <folder>:<name>
• Fixed /verify and /code-review not finding a nested package's own skill when its files were changed from the shell
• Fixed the /claude-api skill saying that ant beta:worker poll --on-work passes trace context to the command
• Fixed the /claude-api skill's C# tracing setup missing spans from the cloud platform clients
• Fixed the /claude-api skill saying that API spans for requests to Claude Platform on AWS can't join the caller's trace
• Fixed hooks that run in PowerShell not blocking when the hook's program exits with code 2, and on Windows PreToolUse and PermissionRequest hooks with "shell": "powershell" failing open when Git for Windows isn't installed
• Fixed a mod's turn.step hook that names a model by alias, such as haiku, failing every request with a model error: the alias now resolves to its model
• Fixed plugins and skills synced from claude.ai being removed, sometimes mid-session, after a disk read error
• Fixed artifact publishes and updates being refused for some ordinary pages, such as pages with certain minified scripts or artifacts Claude could not read first
• Fixed Claude asking for permission on each artifact update for the rest of a turn after the conversation was compacted in that turn
• Fixed fine-grained tool streaming staying off on Amazon Bedrock when ANTHROPIC_BEDROCK_BASE_URL is set to the default bedrock-runtime.<region>.amazonaws.com endpoint
• Fixed the "Waiting for API response" hint flickering behind gateways that send only keepalive pings: routes off Anthropic's backend now wait 45 seconds
• Fixed Claude notifying unrelated GitHub users by writing role names and placeholders as mentions in PRs, issues and comments
• Linux: Fixed sandbox write denies lifting when a background command outlived the session
• Windows: Fixed PowerShell permission checks auto-approving some Set-Location or cd commands that target the current directory and carry extra arguments; these now prompt for approval
• macOS: Fixed the "Install Command Line Developer Tools" dialog opening each time Claude Code starts on a Mac without Xcode or the Command Line Tools
• Self-hosted runner: Fixed --startup-timeout-min stopping a session whose first prompt, such as /code-review, was still working in a subagent; a frozen process is still stopped
• Improved the speed of many git commands Claude Code runs for itself on Windows; on every platform, errors from those commands now show in English even when git is set to another language
• Improved the error when a hooks module is nested too deep to load: it now names the file instead of showing a bare stack-overflow message
• Improved disk-full handling: a Bash command cut off by a full disk now says so and names the folder to free up, and starting on a full temp volume prints a clear message, not a raw ENOSPC error
• Improved the /claude-api skill to offer API tracing alongside SDK tracing when asked to add OpenTelemetry
• Improved the /claude-api skill to check the live docs before saying a feature is unsupported
• Self-hosted runner: Improved sessions that move to a new runner: Claude now sees the tool call that was interrupted, marked as outcome unknown
• Updated the bundled dataviz skill to accept APCA as a text-contrast measure (keeping WCAG 2 ratios where AA conformance is required), add an apca(text, background) function to its palette validator scripts, and say whether a label inside a colored chart fill should be white or near-black
• Updated the /claude-api skill: service account keys and Workload Identity Federation tokens can now manage OpenTelemetry destinations
• Changed sed -i to get the standard Bash prompt and run as written, not a simulated file-edit preview; like other Bash edits, it is no longer restored by /rewind
• Changed claude ultrareview to require workspace trust: it asks on a terminal, else refuses; scripts pass --trust-workspace, which takes no value (put a PR number or base branch before it), or set CLAUDE_CODE_DISABLE_ULTRAREVIEW_TRUST_CHECK=1
• Changed the dangerous rm and rmdir prompt in bypass permissions mode in the Desktop app and VS Code to deny the command at once with a rewrite hint, so unattended sessions keep going
• Changed commands the settings exclude from the sandbox to ask before writing to its write-list paths while the sandbox is enabled but cannot run; the unsandboxed fallback is refused there
• Changed worktree creation and reuse so git no longer fetches objects on demand, in ordinary clones and in partial clones with a Bash sandbox configured; such a partial clone fetches them first
• Changed the /claude-api skill to build Managed Agents subagent teams on multiagent_20261001 with dynamic workflows on by default, instead of coordinator
• [VSCode] Added a log warning that says what to do when dictation or the extension's own requests fail certificate verification, such as behind a TLS-inspecting proxy
• [VSCode] Fixed the Claude panel staying blank after the editor cached an incomplete copy of its files; it now recovers by itself, or says what went wrong and how to fix it
• [VSCode] Fixed Session history filling up with empty "Untitled" sessions each time you start a new session without sending a message
• [VSCode] Fixed long slash-command messages such as /goal filling the chat panel; they now fold behind Show more like other prompts (#97469)
• [VSCode] Fixed long messages not folding behind Show more after the chat panel is made narrower
• [VSCode] Fixed Ctrl+J in the chat input always inserting a newline: it is now left to VS Code and the OS when "ctrl+j" is set to null in the Chat context of ~/.claude/keybindings.json
• [VSCode] Fixed a mod's "From the … plugin" label above the prompt being drawn over the slash command and @-mention menus (#102981)
• [VSCode] Fixed an empty list item, paragraph or code block, and list items renumbered from 1, when pasting copied LaTeX math
• [VSCode] Fixed the feedback error showing only an HTTP status when your organization does not accept feedback
• [VSCode] Improved Edit and Write speed in the chat panel: the wait for new problems after each edit is now 0.75 seconds in most cases, down from 1 to 1.5 seconds
• [Cloud sessions] Fixed the Add connector list in routine forms saying no connectors were available while they were still loading
• [Cloud sessions] Fixed the cloud environment editor shuffling environment variables and adding backslashes to values that contain both kinds of quote
• [Cloud sessions] Fixed the self-hosted environment details dialog in admin settings so its title, tabs and buttons stay in view while only the content scrolls
• [Cloud sessions] Fixed the "read documentation" tool row in cloud sessions, which showed escaped JSON instead of a readable page
• [Cloud sessions] Improved a cloud session's Changes pane, which now says when it lists only pushed commits or only Claude's edits
• [Claude Tag] Fixed Claude in Slack posting a draft you approved for a channel into your DM by mistake; a post with no channel is now refused so it can go to the approved channel
• [Claude Tag] Fixed Allow and Deny on Claude's approval cards in Slack doing nothing when the session had stopped; your answer now restarts the session
• [Claude Tag] Fixed Claude ignoring untagged messages in a Slack channel after its workspace moved to a different Claude organization, including unshared channels on Enterprise Grid
• [Claude Tag] Fixed Claude in a Slack channel posting a threaded reply before reading a newer message someone had just added to that thread
• [Claude Tag] Fixed the Slack page in Claude Tag admin settings saying no workspaces were connected when the list failed to load; it now shows an error with a Retry button
• [Code Review] Fixed a finished review showing no check on the pull request when earlier tries to create it failed; a final try now adds a completed check
• [Code Review] Fixed a push queued behind a running review still starting a review after @claude review stop; its check now closes and says why
