Install GitHub Actions workflows that delete stale git branches safely — the closed-without-merging path plus a scheduled orphan sweep — and enable the native delete_branch_on_merge setting that handles merged PRs. Host-agnostic: no Vercel, Neon or any external service required, works in any GitHub repo. Never deletes a branch that open PRs target as their BASE (that would CLOSE those PRs and destroy a stack). Use when asked to clean up / delete stale, merged, abandoned or orphaned branches…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Branch cleanup Authors GitHub Actions workflows that delete stale branches. **This skill installs workflows; it never deletes anything itself.** At runtime there is no agent and no model call — deterministic bash + `gh` only. Verified GitHub behaviour (the `delete` event, ruleset errors, `gh` footguns, base-branch semantics) lives in [`reference/github-facts.md`](./reference/github-facts.md). Read it before changing any deletion logic. ## The one rule that must never be relaxed **Before deleting ANY branch, check for open PRs that target it as base:** ```bash gh pr list --base <branch> --state open --json number --limit 1000 ``` GitHub documents it plainly: *"If the branch is associated with at least one open pull request, deleting the branch closes the pull requests."* That is often **unrecoverable** — you cannot retarget a closed PR, nor reopen it while its base is missing. Two traps that make this worse than it looks: - **`gh pr list --limit` defaults to 30.** A stack deeper than 30 silently under-reports and the guard passes when it shouldn't. Always pass an explicit high limit. …

How to install
mdr add stealth-factory/skills/branch-cleanup@sha256:10cb79df8d9a4690The line at the top of this page pins the label v1.1.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
