Delete local Git branches whose remote has been removed, including worktrees.

Installation

1
Make sure Claude is on your device and in your terminal.
Skills load from ~/.claude/skills/ when Claude Code starts up — so you need it on your machine first. If you don't have it yet, install it once with the command below, then run claude in any terminal to verify.
One-time setup
```
npm i -g @anthropic-ai/claude-code
```
Already have it? Skip ahead.

Paste into Claude Code or into your terminal.

Install

git clone ht••••••••••••••••••••••••••••••••• •••••••••••••••••• •• ••••• •• ••••••••••••••••••••••••••••••••••••• •• •• •• •••••••••••••••••••••••••••••••••••••••••••••••••• ••••••••••••••••••••••••••••••••••••••

This copies the whole skill folder into ~/.claude/skills/clean-branches-kdlbs/ — the SKILL.md plus any scripts, reference docs, or templates the skill ships with. Safe default: works for every skill.

Faster alternative (instruction-only skills)

Skips the clone and grabs only the SKILL.md file. Don't use this if the skill ships Python scripts, reference markdowns, or asset templates — they won't be downloaded and the skill will fail when it tries to load them.

Quick install (SKILL.md only)

mkdir -p ~/.•••••••••••••••••••••••••••••••••• •• •••• ••••• •••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••• •• ••••••••••••••••••••••••••••••••••••••••••••••

Restart Claude Code.
Quit and reopen Claude Code (or any other agent that loads from ~/.claude/skills/). New skills are picked up on startup.
Just ask Claude.
Skills auto-activate when your request matches the skill's description — no slash command needed. Trigger phrases live in the skill's own frontmatter; you can read them in the “What this skill does” section above.

Prefer to read the source first? Open on GitHub.

When Claude uses it

Delete local branches whose remote has been deleted ([gone]), including their worktrees. Use for branch cleanup after merging PRs.

What this skill does

Clean Branches

Remove local branches that have been deleted on the remote (marked [gone]), including any associated git worktrees.

Steps

Fetch and prune remote refs:
```
git fetch --prune
```
List branches to identify [gone] status:
```
git branch -v
```
Branches with a + prefix have associated worktrees that must be removed before deletion.
List worktrees for reference:
```
git worktree list
```

Remove worktrees and delete [gone] branches:

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

Report which branches and worktrees were removed. If none were [gone], say no cleanup was needed.
