sweep-branches

sweep-branches is a skill for Claude Code, Codex from nirecom/agents. It costs 27 tokens per session (398 once invoked), scanned A, original, MIT.

A Git branch cleanup tool for removing branches that have already been merged. Git branches are separate lines of code work, and merged branches are usually no longer needed.

In plain words
What is it for?
Use it to preview or delete old merged branches, with age limits for local branches and checks for merged pull requests on GitHub.
Why use it?
It reduces clutter from old local and GitHub branches while protecting commonly used branches such as main and develop.

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

sweep-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 4d 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

Reclaims merged-but-undeleted local and remote branches. Local branches are age-gated (default 24 h); remote branches are only PR-merged checked. Protected branches (main, master, develop, release/*) are never deleted.

Procedure

SB-1. Resolve $AGENTS_CONFIG_DIR from the environment; abort with a clear error if unset. SB-2. Invoke the sweeper script (no flag = deletes; --dry-run = preview): bash "$AGENTS_CONFIG_DIR/bin/sweep-branches.sh" [--dry-run] [--min-age-hours N] [--ci-mode] SB-3. Print the script's stdout verbatim. Do not summarize or filter.

Forward the user's flags verbatim. Add no flags of your own.

Rules

  • Deletes by default; --dry-run must be explicit to preview only.
  • --delete-no-pr alone deletes no-PR local branches; add --dry-run to preview.
  • Remote branches use gh api -X DELETE (REST API); local branches use git branch -D with SWEEP_BRANCHES_SKILL=1 guard.
  • Remote branches are not age-gated (only PR-merged check); local branches are age-gated via --min-age-hours.
  • main, master, develop, release/* are never deleted.
  • Non-GitHub remotes are skipped (non-fatal).
  • Per-branch failures are non-fatal: warning printed, sweep continues.
  • After remote deletion, local tracking refs (origin/<branch>) persist until git fetch --prune.

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.
