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

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 blocking question tool: AskUserQuestion in Claude Code (call ToolSearch with select:AskUserQuestion first if its schema isn't loaded), request_user_input in Codex, ask_user in Gemini, ask_user in Pi (requires the pi-ask-user extension). Fall back to presenting the list in chat only when no blocking tool exists in the harness or the call errors (e.g., Codex edit modes) — not because a schema load is required. Never silently skip the question.

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:

1. Check if it has an associated worktree (git worktree list | grep "\\[$branch\\]")
2. If a worktree exists and is not the main repo root, remove it first: git worktree remove --force "$worktree_path"
3. 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.
