Changelog
What's changed
- 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 --amendis blocked when the commit wasn't made by the agent this session, andterraform destroy/pulumi destroy/cdk destroyare blocked unless you asked for the specific stack - 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.sessionUrlsetting to omit the claude.ai session link from commits and PRs in web and Remote Control sessions - Added
/config --helpto list all available shorthand keys for/config key=value - Changed
/configtoggle behavior: Enter and Space both change the selected setting, and Esc now saves and closes instead of reverting - Removed the startup "setup issues" line under the logo — run
/doctorto see configuration issues or use--debug - Fixed
thinking.disabled.display: Extra inputs are not permitted400 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
