Clean up local branches whose remote tracking branch is gone. Use when the user says "clean up branches", "delete gone branches", "prune local branches", "clean gone", or wants to remove stale local branches that no longer exist on the remote. Also handles removing associated worktrees for branches

Clean up local branches whose remote tracking branch is gone.

Also handles removing associated worktrees for branches that have them.About this skill
Clean Gone Branches
Delete local branches whose remote tracking branch has been deleted, including any associated worktrees.
Workflow
Step 1: Discover gone branches
Run the discovery script to fetch the latest remote state and identify gone branches:
bash scripts/clean-gone
The script runs git fetch --prune first, then parses git branch -vv for branches marked : gone].
If the script outputs __NONE__, report that no stale branches were found and stop.
Step 2: Present branches and ask for confirmation
Show the user the list of branches that will be deleted. Format as a simple list:
These local branches have been deleted from the remote:
- feature/old-thing
- bugfix/resolved-issue
- experiment/abandoned
Delete all of them? (y/n)
Wait for the user's answer using the platform's question tool (e.g., ask_user in Copilot CLI). If no question tool is available, present the list and wait for the user's reply before proceeding.
This is a yes-or-no decision on the entire list -- do not offer multi-selection or per-branch choices.
Step 3: Delete confirmed branches
If the user confirms, delete each branch. For each branch:
- Check if it has an associated worktree (
git worktree list | grep "\\[$branch\\]") - If a worktree exists and is not the main repo root, remove it first:
git worktree remove --force "$worktree_path" - Delete the branch:
git branch -D "$branch"
Report results as you go:
Removed worktree: .worktrees/feature/old-thing
Deleted branch: feature/old-thing
Deleted branch: bugfix/resolved-issue
Deleted branch: experiment/abandoned
Cleaned up 3 branches.
If the user declines, acknowledge and stop without deleting anything.
