Git Cleanup

Safely clean up accumulated git worktrees and local branches by categorizing them into: safely deletable (merged), potentially related (similar themes), and active work (keep).

When to Use

• When the user has accumulated many local branches and worktrees
• When branches have been merged but not cleaned up locally
• When remote branches have been deleted but local tracking branches remain

When NOT to Use

• Do not use for remote branch management (this is local cleanup only)
• Do not use for repository maintenance tasks like gc or prune
• Not designed for headless or non-interactive automation (requires user confirmations at two gates)

Core Principle: SAFETY FIRST

Never delete anything without explicit user confirmation. This skill uses a gated workflow where users must approve each step before any destructive action.
