clean-gone-branches

clean-gone-branches is a skill for Claude Code from fcakyon/claude-codex-settings. It costs 44 tokens per session (222 once invoked), scanned A, original, Apache-2.0.

A procedure for removing local Git branches that were deleted from the remote repository, while checking for linked worktrees first.

In plain words
What is it for?
Use it to prune remote references, find branches marked as gone, remove their worktrees when necessary, and delete those local branches.
Why use it?
It clears outdated branch references without deleting a branch that still has an active worktree, which is a separate working directory linked to Git.

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

clean-gone-branches 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 7d 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.

What it actually says

Clean Gone Branches

Remove local git branches that have been deleted from the remote.

Process

  1. Update remote references

    • Run git fetch --prune.
  2. Inspect local state

    • Run git branch -vv to find branches marked as [gone].
    • Run git worktree list to see whether any of those branches still have worktrees.
  3. Remove worktrees first

    • For each [gone] branch that still has a worktree, remove the worktree before deleting the branch.
  4. Delete the gone branches

    • Delete each local branch marked as [gone].
  5. Report the result

    • List removed worktrees and deleted branches.
    • If there are no [gone] branches, report that nothing needed cleanup.
Changes

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.
