# Agent Skill to Clean Gone

**Summary:** Agent Skill to Clean Gone is a verified SKILL blueprint on Promptally in Fullstack & Backend Engineering optimized for leading AI models. Cleans up all git branches marked as gone (branches that have been deleted on the remote but still exist locally), including removing associated worktrees. Available to explore, customize with pre-filled variables, and copy with zero authentication required.

## Your Task

You need to execute the following bash commands to clean up stale local branches that have been deleted from the remote repository.

## Commands to Execute

1. **First, list branches to identify any with [gone] status**
   Execute this command:
   ```bash
   git branch -v
   ```
   
   Note: Branches with a '+' prefix have associated worktrees and must have their worktrees removed before deletion.

2. **Next, identify worktrees that need to be removed for [gone] branches**
   Execute this command:
   ```bash
   git worktree list
   ```

3. **Finally, remove worktrees and delete [gone] branches (handles both regular and worktree branches)**
   Execute this command:
   ```bash
   # Process all [gone] branches, removing '+' prefix if present
   git branch -v | grep '\[gone\]' | sed 's/^[+* ]//' | awk '{print $1}' | while read branch; do
     echo "Processing branch: $branch"
     # Find and remove worktree if it exists
     worktree=$(git worktree list | grep "\\[$branch\\]" | awk '{print $1}')
     if [ ! -z "$worktree" ] && [ "$worktree" != "$(git rev-parse --show-toplevel)" ]; then
       echo "  Removing worktree: $worktree"
       git worktree remove --force "$worktree"
     fi
     # Delete the branch
     echo "  Deleting branch: $branch"
     git branch -D "$branch"
   done
   ```

## Expected Behavior

After executing these commands, you will:

- See a list of all local branches with their status
- Identify and remove any worktrees associated with [gone] branches
- Delete all branches marked as [gone]
- Provide feedback on which worktrees and branches were removed

If no branches are marked as [gone], report that no cleanup was needed.
