Auto-retire preview deployments when their PR is merged or closed
Listens for GitHub pull request merged or closed events and deletes the associated Vercel preview deployments and their aliases.
How it runs
The automated pipeline, trigger to output.

- LogicConfirm real close/merge and parse branch

- ActionDelete deployments and remove aliasesVercel
- OutputConfirm retired previews in SlackSlack
What it does
Keeps preview deployments from piling up after they stop mattering. When a pull request is merged or closed, it finds the preview deployments tied to that PR's branch and deletes them along with their aliases.
When to use it
Use it when closed PRs leave behind dozens of live preview URLs that still serve traffic, hold storage, and count against bandwidth. Retiring them at PR close keeps the deployment list clean and the bill honest.
How it works
- 1A GitHub webhook fires when a pull request is closed or merged.
- 2A logic step confirms the event is a real close or merge, not just an edit, and extracts the branch name.
- 3The flow queries the Vercel API for preview deployments matching that branch.
- 4It deletes each matching deployment and removes its preview aliases.
- 5It posts a brief confirmation to Slack listing how many previews were retired and the storage reclaimed.
