Install a GitHub Actions workflow that deletes a branch's Vercel PREVIEW deployments when that branch is deleted — every deployment it accumulated, not just the aliased URL (Vercel keeps one immutable deployment per push, so a 15-push branch leaves 15 live URLs). Requires Vercel; if you just want stale git branches deleted, use the branch-cleanup skill instead. Use when asked to clean up / delete orphaned Vercel preview deployments, stop preview deployments piling up, remove previews for…
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
# Vercel preview cleanup
Authors a GitHub Actions workflow that removes a branch's preview deployments once the
branch is gone. **This skill installs workflows; it never deletes anything itself.** At
runtime there is no agent and no model call — deterministic bash + `curl` only.
Verified API detail (endpoints, pagination, rate limits, retention) lives in
[`reference/vercel-api.md`](./reference/vercel-api.md) — read it before changing the
delete logic.
## Step 0 — prerequisites (check before installing)
This skill is **downstream of branch deletion**. If branches are never deleted, the
`delete` event never fires and this workflow looks broken when it isn't.
1. **`delete_branch_on_merge` is on:**
`gh api repos/{owner}/{repo} --jq .delete_branch_on_merge`
→ if `false`, install [`branch-cleanup`](../branch-cleanup/SKILL.md) first (it enables
this and adds the closed-unmerged + orphan-sweep paths).
2. **A branch-cleanup workflow exists** (`.github/workflows/` — closed-unmerged path).
Without it, only *merged* branches get deleted; abandoned ones linger forever and so
do their previews.

How to install
mdr add stealth-factory/skills/vercel-preview-cleanup@sha256:68cf0964b17a2e7aThe line at the top of this page pins the label v1.0.1, 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.
