Clean Up Git Repository

Perform git repository cleanup operations based on the analysis from /git-tools:analyze-git.

IMPORTANT: This command performs DESTRUCTIVE operations. Run /git-tools:analyze-git first to review what will be deleted.

Prerequisites

You MUST run /git-tools:analyze-git before using this command to understand what will be deleted.

Step 1: Clean Gone Branches with Worktrees

Run the following command to remove worktrees and delete branches marked as [gone]:

git branch -v | grep '\[gone\]' | sed 's/^[+* ]//' | awk '{print $1}' | while read branch; do
  echo "Processing branch: $branch"
  worktree=$(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
  echo "  Deleting branch: $branch"
  git branch -D "$branch"
done

After completion, report:

• Number of worktrees removed
• Number of branches deleted
• Any errors encountered

Step 2: Prune Stale Worktrees

Run the following command to prune worktrees marked as prunable:

git worktree prune -v

Report the output showing which worktrees were pruned.

Step 3: Clean Closed Dependabot Branches

IMPORTANT: Before deleting, verify these are truly closed/merged by checking the PR list.

For each dependabot branch with a CLOSED or MERGED PR:

1. First, update remote references:

git fetch --prune

2. The fetch with --prune will automatically remove stale remote references

Report:

• Number of dependabot branches cleaned
• Any branches that still remain (likely have OPEN PRs)

Step 4: Final Verification

After all cleanup operations:

1. List remaining local branches:

git branch

2. List remaining remote branches:

git branch -r

3. List remaining worktrees:

git worktree list

Step 5: Provide Cleanup Summary

Create a summary report with:

1. Branches Deleted: Total count and names
2. Worktrees Removed: Total count and paths
3. Remote Branches Cleaned: Total count (dependabot)
4. Final Inventory: Current count of local branches, remote branches, and worktrees
5. Space Saved: Approximate disk space reclaimed (if measurable)

Safety Notes

• This command performs DESTRUCTIVE operations
• Always run /git-tools:analyze-git first
• Operations cannot be easily undone (branches are deleted, not archived)
• Main branch (dev, master) and current branch are preserved by design
• Active dependabot branches (OPEN PRs) are preserved
