What problem does it solve? Local repositories accumulate stale branches whose remote counterparts have been deleted, cluttering branch lists and leaving orphaned worktrees on disk. This Skill automates the cleanup of those [gone] branches in a single pass. ## Core Features & Use Cases - Gone Branch Detection: Scans git branch -v output for [gone] markers to identify branches deleted on the remote. - Worktree Removal: Detects worktrees attached to stale branches and removes them with git worktree remove --force before deleting the branch. - Safe Deletion: Only touches branches explicitly marked [gone], never deletes the current working tree root, and reports every removal. - Use Case: After a sprint where many feature branches were merged and deleted on the remote, run this Skill to clean up all local leftovers and their worktrees at once. ## Quick Start Ask the assistant to prune branches or clean up gone branches in the current repository.
