Install the worktree-isolation skill

A skill is a folder. Copy it into your agent's skills folder and the agent loads it when the task matches its description. 

git clone --depth 1 https://github.com/a5c-ai/babysitter.git /tmp/babysitter
mkdir -p ~/.claude/skills
cp -r /tmp/babysitter/library/methodologies/pilot-shell/skills/worktree-isolation ~/.claude/skills/worktree-isolation
available in every project

In the Claude apps, zip the folder and upload it from the Skills settings. The folder on GitHub

Create worktree with feature branch

git worktree add .claude/worktrees/ -b feature/ cd .claude/worktrees/ npm install # or equivalent package manager

### 2. Worktree Detection
- Check if currently inside a worktree
- Identify the base branch
- Detect worktree state (clean, dirty, conflicts)

### 3. Worktree Sync
- Pull latest changes from base branch into worktree
- Rebase feature branch on updated base
- Resolve conflicts if needed

### 4. Worktree Diff
- Generate diff between worktree and base branch
- Summarize changes by file and type
- Calculate diff statistics

### 5. Worktree Cleanup
- Remove worktree after successful merge
- Delete feature branch
- Prune stale worktree references

### 6. Worktree Status
- List all active worktrees
- Show branch and status for each
- Identify orphaned worktrees

## Branch Naming Convention

| Mode | Pattern | Example |
|------|---------|---------|
| Feature | `feature/<slug>` | `feature/add-user-auth` |
| Bugfix | `bugfix/<slug>` | `bugfix/fix-payment-race` |
| Quick | `quick/<number>` | `quick/042` |

## Multiple Parallel Sessions

Worktrees enable multiple Pilot Shell sessions to work simultaneously without interference, as each operates in its own filesystem directory with its own branch.
