# Using Git Worktrees ## Overview Git worktrees create isolated workspaces sharing the same repository, allowing work on multiple branches simultaneously without switching. **Core principle:** Systematic directory selection + safety verification = reliable isolation. **Announce at start:** "I'm using the using-git-worktrees skill to set up an isolated workspace." ## Directory Selection Process Follow this priority order: ### 1. Check Existing Directories ```bash # Check in priority order ls -d .worktrees 2>/dev/null # Preferred (hidden) ls -d worktrees 2>/dev/null # Alternative ``` **If found:** Use that directory. If both exist, `.worktrees` wins. ### 2. Check CLAUDE.md ```bash grep -i "worktree.*director" CLAUDE.md 2>/dev/null ``` **If preference specified:** Use it without asking. ### 3. Ask User If no directory exists and no CLAUDE.md preference: ``` No worktree directory found. Where should I create worktrees? 1. .worktrees/ (project-local, hidden) 2. ~/.config/superpowers/worktrees/<project-name>/ (global location) Which would you prefer? ``` ## Safety Verification ### For Project-Local Directories (.worktrees or worktrees) **MUST verify directory is ignored before creating worktree:** ```bash # Check if directory is ignored (respects local, global, and system gitignore) git check-ignore -q .worktrees 2>/dev/null || git check-ignore -q worktrees 2>/dev/null ``` **If NOT ignored:** Per Jesse's rule "Fix broken things immediately": 1.
