cleanup

A command that removes Git branches whose changes are already merged into a base branch, both on your computer and optionally on the shared remote repository.

In plain words
What is it for?
Use it after merges to clean up old feature and bug-fix branches. You can preview the proposed deletions or limit cleanup to local branches.
Why use it?
It clears out stale branches without deleting unfinished work. It also protects important long-lived branches and the branch you are currently using.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cleanup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Branch Cleanup

Delete the branches that are fully merged into a base branch, both locally and on the remote, then report what was removed and what was kept. Long-lived branches are protected, the branch you are currently on is never touched, and unmerged work is left strictly alone (only safe git branch -d, never force-delete -D).

This is housekeeping after merges land: it removes the stale feat/*, fix/*, and similar branches whose commits already live in the base, so git branch stops being a junkyard. It does not decide what to merge and it never deletes anything that is not already merged.

Arguments

$ARGUMENTS is optional and freeform:

  • A branch name (e.g. develop, main) sets the base to compare against. If omitted, use the repository's default branch (see step 1).
  • --dry-run lists what would be deleted and stops, without deleting or asking.
  • --local-only skips remote deletion entirely (never touches origin).

Examples: /cleanup, /cleanup develop, /cleanup main --dry-run, /cleanup --local-only.

Protected branches

Never delete, regardless of merge status:

  • The base branch itself.
  • The current branch (the one HEAD points at).
  • A default keep-list of common long-lived branches: main, master, develop, development, preview, staging, production, release.

If the user has named other long-lived branches in this repo's CLAUDE.md or in the conversation, treat those as protected too.

Steps

  1. Determine the base branch. If $ARGUMENTS names one, use it. Otherwise detect the repo default:

    git remote show origin 2>/dev/null | sed -n 's/.*HEAD branch: //p'
    

    If that yields nothing (no remote), fall back to main if it exists, else master. Confirm the chosen base out loud before deleting anything.

  2. Refresh the branch list so merged-state and remote-tracking refs are current:

    git fetch --prune origin
    

    (Skip the fetch if there is no origin remote.)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cleanup is a command published in the GitHub repository cwakim/claude-plugins (2 stars, last pushed 12d ago), licensed MIT. It adds 28 tokens to every session and 1,076 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
