Claude Code 2.1.183

This release brings significant safety improvements, blocking destructive git commands like `git reset --hard` and infrastructure commands like `terraform destroy` unless specifically requested, safeguarding your local work and environments. New features include warnings for deprecated models and an option to omit session links from commits. A range of reliability and user experience fixes address issues like silent turns, empty WebSearch results in subagents, and tmux teammate pane failures, ensuring a more robust and predictable workflow.

Added

  • Added a warning when the requested model is deprecated or automatically updated to a newer model, shown on stderr in print mode (`-p`) and now also covering models set in agent frontmatter
  • Added `attribution.sessionUrl` setting to omit the claude.ai session link from commits and PRs in web and Remote Control sessions
  • Added `/config --help` to list all available shorthand keys for `/config key=value`

Improved

  • Improved auto mode safety: destructive git commands (`git reset --hard`, `git checkout -- .`, `git clean -fd`, `git stash drop`) are now blocked when you didn't ask to discard local work, `git commit --amend` is blocked when the commit wasn't made by the agent this session, and `terraform destroy`/`pulumi destroy`/`cdk destroy` are blocked unless you asked for the specific stack

Changed

  • Changed `/config` toggle behavior: Enter and Space both change the selected setting, and Esc now saves and closes instead of reverting

Fixed

  • Fixed `thinking.disabled.display: Extra inputs are not permitted` 400 errors on subagent spawns and session-title generation for affected configurations
  • Fixed WebSearch returning empty results in subagents
  • Fixed the terminal cursor being stranded above the prompt after navigating history in vim mode with the native cursor enabled
  • Fixed fullscreen TUI corruption (statusline mid-screen, duplicated spinner rows, merged text) in Windows Terminal under heavy nested-subagent load
  • Fixed turns silently completing with no visible output when the model returned only a thinking block; Claude now re-prompts once
  • Fixed user-level skills appearing multiple times in slash-command autocomplete when multiple plugins are enabled
  • Fixed MCP servers requiring authentication exposing auth-stub tools to the model in headless/SDK mode
  • Fixed tmux teammate panes failing to launch when the shell has slow rc-file initialization, and keystrokes typed during agent spawn leaking into the new tmux pane instead of the leader prompt
  • Fixed background tasks started by a teammate being killed when the teammate finishes a turn
  • Fixed scheduled task and webhook trigger deliveries being treated as keyboard input; they now classify as task notifications and can no longer approve a pending action or set the session title in auto mode
  • Fixed focus mode showing "Ran N PostToolUse hooks" timing lines under each response

Removed

  • Removed the startup "setup issues" line under the logo — run `/doctor` to see configuration issues or use `--debug`
