Scheduled staleness sweep of open-PR Vercel previews
On a daily schedule, re-smoke-tests the live preview for every open pull request and posts a single digest to Slack listing which previews are now broken or stale so reviewers…

What it does
Once a day this workflow lists every open pull request with a Vercel preview, re-runs a smoke check against each preview URL, and posts one consolidated Slack digest ranking previews as healthy, broken, or stale — so reviewers never waste time on a preview that died since it was built.
When to use it
Use it on busy repos where PRs sit open for days and their previews silently rot (backend changed, env expired, deploy reaped). A daily sweep keeps the review queue honest.
How it works
- 1A daily schedule trigger starts the sweep.
- 2The flow lists open PRs and their latest preview deployments from GitHub and Vercel.
- 3An HTTP smoke request runs against each preview URL.
- 4A logic step buckets each into healthy, broken, or stale based on status and deploy age.
- 5A single Slack digest posts the buckets with direct links so the team can re-trigger or close as needed.
