At a glance

Audits stale Git worktrees and branches with a bundled script, classifies each one, and deletes only after you approve the exact candidates.

  • Works in 5 steps: Run the audit from any worktree in the… → Interpret classifications → Present one compact table split into… → …
  • Auditing a repository with many leftover worktrees and local branches
  • SKILL.md covers Workflow, Proving a merge, Repo-approved deletion policy and Broken registrations, plus 2 more sections
  • Runs Shell scripts from its folder; calls git, bash and gh

What it does

The skill treats cleanup as a destructive action. It audits first, groups candidates by the reason they can be deleted, and asks for one explicit approval before removing anything, unless your request already names the exact targets. A bundled cleanup.sh script does the classification so the results are deterministic, and removal of managed worktrees goes through the repository's own lifecycle.

The audit command can fetch and prune the remote, look up each branch's pull request with the gh CLI (which confirms a merge, at roughly a second per branch), and flag clean branches idle past a day threshold, with 15 days as the approved default. Classifications include protected branches such as main and canary, the current worktree, dirty worktrees that are kept, and candidates whose tip is merged into the base or whose pull request is merged or closed.

When your agent uses it

  • Auditing a repository with many leftover worktrees and local branches
  • Finding branches whose pull request was merged or closed so they can go
  • Checking which worktrees hold uncommitted work before removing anything

Example prompts

  • “Audit my stale worktrees and show me what is safe to delete.”
  • “Clean up the branches that were merged into canary, using PR status from GitHub.”
  • “List which worktrees are dirty so I do not lose anything before cleanup.”

Requirements

  • Bash and Git
  • An authenticated gh CLI for pull request lookups

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Run the audit from any worktree in the repository
  2. Interpret classifications
  3. Present one compact table split into three groups: deletable now (all candidate-*), needs a manual check (review-*), and protected. Keep…
  4. After approval, use the repository's worktree lifecycle workflow when it manages services or other resources alongside a checkout; the…
  5. Run the audit again and report

What it can do on your machine

Read from SKILL.md and the folder at commit 1863542. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • git
    • bash
    • gh

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git and gh, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Git Worktree Cleanup loads about 2.8k tokens when it runs. Until then it costs about 31 tokens; SKILL.md has 1,410 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~31
When it runs · the whole SKILL.md, loaded when a task matches
~2.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,410 words (~2,788 tokens).

“Use the bundled script to make classification deterministic. Treat cleanup as a destructive action: audit first, show the exact candidates grouped by why they are deletable, and obtain one explicit approval before applying deletion unless the user's current request already…”
