 - Start-workshop skill for multi-agent design workshops
 
 ### Fixed
+- Added worktree boundary rules to CLAUDE.md — agents must stay within the git root, no navigating to sibling worktrees or above the repo
+- Plan-sprint skill now enforces worktree-relative paths in generated briefings
 - Worktree-update skill now discovers branches dynamically via `git worktree list` instead of relying on hardcoded branch names — fixes missed branches like `planning`
