Claude Code 2.1.216 download

- Added sandbox.filesystem.disabled setting to skip filesystem isolation while keeping network egress control
- Fixed a slowdown in long sessions where message normalization cost grew quadratically with the number of turns, causing multi-second stalls and slow resumes
- Fixed auto mode denying commands with "HTTP 401" classifier errors after the OAuth token expired or rotated mid-session
- Fixed AskUserQuestion telling Claude to continue even when your answer asked it to wait or explain first — free-text answers now get neutral wording
- Fixed Claude Code on the web re-asking the same question and dropping your answer after the session sat idle for a few minutes
- Fixed @-mentions silently attaching nothing after file-modifying hooks, vim dot-repeat of c-operators and paste, statusline running twice on resume, and resume-picker hangs on failure
- Fixed resumed background agent sessions reverting to the default agent: the agent's prompt and tool restrictions are now restored
- Fixed worktree-isolated subagents redirecting git into the shared checkout via git -C, --git-dir, or GIT_DIR/GIT_WORK_TREE
- Fixed worktree sessions landing in another project's leftover worktree when the working directory did not match the selected project
- Fixed background sessions whose worktree has no git repository being undeletable
- Fixed claude daemon stop --any potentially terminating an unrelated process via a stale legacy daemon lockfile
- Fixed Esc-Esc at an idle prompt not opening the rewind picker in long-running sessions with background tasks
- Fixed Bash command permission checking for compound statements with redirects inside && lists or negations
- Fixed pressing Ctrl+X twice in the agent list failing to delete a session, and deleted sessions reappearing when their background worker had died
- Fixed background subagents getting cancelled when a high-priority message arrives during their startup window
- Fixed mouse and focus garbage in the terminal while a GUI editor from /memory, /plan, /keybindings, or Ctrl+G is open; /memory no longer waits for the editor to close
- Fixed Claude-in-Chrome 403-looping on reconnect when the session's OAuth token lacks a required scope
- Fixed workflow saves and scheduled-task writes following a symlink at .claude, which could redirect writes outside the project
- Fixed MCP re-authenticate revoking working credentials before the new sign-in succeeds, and the reconnect needs-auth message in background sessions pointing at an unusable command
- Fixed read-only commands on Windows accessing network paths without a permission prompt
- Fixed Bash command parsing of non-ASCII characters to match real shell word boundaries
- Fixed PowerShell tool permission validation of commands containing invisible Unicode characters
- Fixed dialogs in fullscreen mode stretching past the right-hand edge of their panel
- Fixed the /config settings list in fullscreen mode clipping its keyboard-hint footer
- Fixed the transcript-mode (Ctrl+O) footer hint wrapping on terminals narrower than 104 columns
- Fixed the Prometheus metrics endpoint (OTEL_METRICS_EXPORTER=prometheus) emitting invalid # UNIT lines
- Fixed skills and commands changed during a session not appearing in the slash menu until restart
- Fixed plugin skills with a name frontmatter field losing their plugin prefix in slash-command autocomplete
- Fixed telemetry misreporting permission denials: failed permission-prompt requests no longer count as user rejections, and user interrupts are now reported as user aborts instead of rejections
- Improved the /fork confirmation to one line with the new session's name, claude attach id, and a note when the copy shares your checkout
- Improved validation of git and gh command arguments in the PowerShell tool
- Improved the /ultrareview diff-too-large error to show configured limits, measured diff size, and largest contributing files
- Improved /code-review ultra empty-diff message to name the exact base ref and suggest passing an explicit base
- Improved the spend limit adjustment prompt to show the server's reason when a spend limit change is rejected
- /context now shows an explicit warning when the conversation exceeds the context window, and a failed /compact displays as an error
- /rewind no longer restores or deletes files through symlinks or hard links at tracked paths and reports how many paths it skipped
- Background sessions: /mcp and /install-github-app now park a "needs input" request in the agent view when no client is attached
- Updated the bundled dataviz skill: reordered the default chart palette and fixed guidance that suggested direct labels for four-series charts
- [VSCode] Fixed right-to-left text (Arabic, Hebrew, Persian) rendering in the wrong order when mixed with English or code
- Fixed cloud sessions dropping the in-flight message when the session's container restarts mid-turn — the interrupted turn now re-runs on resume instead of leaving the session unresponsive
