git-cleanup

git-cleanup is a skill for Claude Code from RedHatProductSecurity/prodsec-skills. It costs 42 tokens per session (3,061 once invoked), scanned A, original, Apache-2.0.

A local Git cleanup guide for reviewing branches and worktrees before removing old ones. It distinguishes merged, squash-merged, related, and active work.

In plain words
What is it for?
Use it to inspect accumulated local branches and worktrees, identify merged or obsolete work, and safely remove approved items.
Why use it?
It reduces clutter while lowering the risk of deleting work that is still needed. It requires confirmation before destructive steps.

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

git-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 9d 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.

Git Cleanup

Safely clean up accumulated git worktrees and local branches by categorizing them into: safely deletable (merged), potentially related (similar themes), and active work (keep).

When to Use

  • When the user has accumulated many local branches and worktrees
  • When branches have been merged but not cleaned up locally
  • When remote branches have been deleted but local tracking branches remain

When NOT to Use

  • Do not use for remote branch management (this is local cleanup only)
  • Do not use for repository maintenance tasks like gc or prune
  • Not designed for headless or non-interactive automation (requires user confirmations at two gates)

Core Principle: SAFETY FIRST

Never delete anything without explicit user confirmation. This skill uses a gated workflow where users must approve each step before any destructive action.

Critical Implementation Notes

Squash-Merged Branches Require Force Delete

IMPORTANT: git branch -d will ALWAYS fail for squash-merged branches because git cannot detect that the work was incorporated. This is expected behavior, not an error.

When you identify a branch as squash-merged:

  • Plan to use git branch -D (force delete) from the start
  • Do NOT try git branch -d first and then ask again for -D - this wastes user confirmations
  • In the confirmation step, show git branch -D for squash-merged branches

Group Related Branches BEFORE Categorization

MANDATORY: Before categorizing individual branches, group them by name prefix:

# Extract common prefixes from branch names
# e.g., feature/auth-*, feature/api-*, fix/login-*

Branches sharing a prefix (e.g., feature/api, feature/api-v2, feature/api-refactor) are almost certainly related iterations. Analyze them as a group:

  1. Find the oldest and newest by commit date
  2. Check if newer branches contain commits from older ones
  3. Check which PRs merged work from each
  4. Determine if older branches are superseded

Present related branches together with a clear recommendation, not scattered across categories.
