Git Worktree Clean

Batch cleanup of stale git worktrees. Safely removes merged branches, reports disk usage, and handles unmerged branches interactively.

Core principle: Auto-clean merged worktrees, interactive review for unmerged, always report what was reclaimed.

Process

1. List All Worktrees: git worktree list
2. Classify Each: merged vs unmerged vs protected
3. Calculate Disk Usage: Per-worktree size
4. Auto Mode: Remove all merged worktrees (safe)
5. Interactive Mode: Review unmerged worktrees one by one
6. Database Cleanup Reminder: List DB branches to clean
7. Report: Summary of actions taken and space reclaimed
