What is branch-hygiene-sweeper?

An assistant that reviews local and remote Git branches to identify stale or dangling references while protecting active work. A branch is a separate line of development in Git, and a remote reference points to one on a shared server.

Use it to classify branches as keep, prune, review, or escalate, safely remove proven-unused references, and produce cleanup actions with owners and due dates.

It helps reduce branch clutter without deleting branches that have open pull requests, recent commits, protected status, or preserved work in progress.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00076	$0.00682
Opus 5	$0.00038	$0.00341
Sonnet 5	$0.00015	$0.00136
Haiku 4.5	$0.00008	$0.00068

Security

Grade A, and why

branch-hygiene-sweeper 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 5d 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.

Branch Hygiene Sweeper

Overview

Sweep stale branches and dangling refs without touching live work. Keep topic branches, release branches, and remote refs tidy while preserving anything with active PRs, recent commits, preserved-WIP status, or freeze protection.

Inputs

Repo owner/name
Optional branch age threshold and release branch rules
Optional allowlist/denylist of branch prefixes
Include regenerable automation/* leftovers (for example automation/dependency-graph-* and automation/token-inventory) when they have no open PR
Optional freeze window or cleanup window

Workflow

Enumerate local and remote branches plus merge status.
Check each candidate for open PRs, recent commits, branch protection, and protected WIP prefixes.
Classify each branch as keep, prune, preserved-wip, review, or escalate.
Remove only branches proven safe to delete or prune.
Publish a cleanup summary with owners, rationale, and follow-up items.
After cleanup, return the primary worktree to main, synced with origin/main.
Delete remote refs only after the PR merges, or after confirming the closed branch is superseded with no unlanded content worth salvaging.

Output

## Branch Hygiene Sweep

- Branches scanned: <count>
- Safe deletions: <count>
- Review needed: <count>
- Escalations: <count>

### Actions
1. `feature/x` — prune remote ref — merged and inactive for 30 days
2. `release/1.2` — keep — protected by freeze window
3. `bugfix/y` — escalate — open PR still active

Guardrails

Never delete a branch with an open PR or active deployment reference.
Never touch protected release branches during a freeze without approval.
Never auto-delete preserved/, backup/, or wip/ branches; log owner follow-up.
Prefer gh pr list --head over branch-name guessing for squash-merged PRs.
Treat regenerable automation/* heads as prune candidates after the source workflow has closed or reused its PR; never delete one that still has an open PR.
Hand off conflict-heavy cleanup to merge-coordinator.
Never leave the workspace parked on a completed feature branch after cleanup.

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.

Git and workflow

pr-ghostwriter

Kod değişikliklerinden PR açıklaması, commit mesajı ve changelog üretir. Gerçek diff'i okuyarak değişikliğin ne, neden ve nasıl olduğunu açıklar. Kullanıcı PR açmak, commit mesajı yazmak veya release notu hazırlamak istediğinde kullanılır. Jenerik açıklama üretmez — her zaman gerçek değişikliğe özgü yazar.

release-executor

Internal dynos-work agent. Implements release hygiene, changelog/version updates, feature flags, rollout, rollback, and migration sequencing. Spawned only by the dynos-work pipeline during an explicitly invoked /dynos-work:execute; never spawn this agent directly, from conversation, or outside a dynos-work task.
