Release Notes
- Added path parameter to the EnterWorktree tool to switch into an existing worktree of the current repository

- Added background monitor support for plugins via a top-level monitors manifest key that auto-arms at session start or on skill invoke
- /proactive is now an alias for /loop
- Improved stalled API stream handling: streams now abort after 5 minutes of no data and retry non-streaming instead of hanging indefinitely
- Improved network error messages: connection errors now show a retry message immediately instead of a silent spinner
- Improved file write display: long single-line writes (e.g. minified JSON) are now truncated in the UI instead of paginating across many screens
- Improved /doctor layout with status icons; press f to have Claude fix reported issues
- Improved /config labels and descriptions for clarity
- Improved skill description handling: raised the listing cap from 250 to 1,536 characters and added a startup warning when descriptions are truncated
- Improved WebFetch to strip <style> and <script> contents from fetched pages so CSS-heavy pages no longer exhaust the content budget before reaching actual text
- Improved stale agent worktree cleanup to remove worktrees whose PR was squash-merged instead of keeping them indefinitely
- Improved MCP large-output truncation prompt to give format-specific recipes (e.g. jq for JSON, computed Read chunk si
