name: git-worktree description: Internal skill for workspace isolation. Detects current git state and offers worktree/branch options. Called by iterative:implementing, not user-invocable. user-invocable: false

Git Worktree (Workspace Isolation)

Ensures agent has an isolated workspace to avoid conflicts with human work.

When Called

• At the start of iterative:implementing skill
• At the start of feature work requiring isolation from the current branch
• When workspace isolation is needed
• Not directly invocable by users

Workflow

1. Sync with remote. Pull latest from default branch.
2. Detect current state. Check if in worktree (git rev-parse --git-dir contains /worktrees/), get current branch (git branch --show-current), get default branch (git remote show origin | grep "HEAD branch").
3. Choose workspace based on current state:
   • Already in worktree: confirm it's for this feature, then proceed
   • On default branch: ask the user — A) Create worktree (recommended), B) Create branch, C) Continue on main (requires explicit consent)
   • On feature branch: ask the user — A) Continue on this branch, B) Create new worktree
4. Execute choice. If worktree: git worktree add ../[repo]-[branch] -b [branch]. If new branch: git checkout -b [branch-name]. If continue: proceed.
5. Verify. Report: "Ready on branch [name] in [directory]"

Worktree Creation

When creating a worktree:

1. Generate branch name from feature/task context
2. Create worktree: git worktree add ../[repo]-[branch] -b [branch]
3. Copy necessary files (.env, etc.) if they exist
4. Verify worktree is functional

Output

Returns to calling skill:

• Branch name
• Directory path (if worktree created)
• Isolation status confirmed
