Post-merge bump deploy watcher with rollback alert
After a lockfile-changing PR merges, watches the resulting Vercel deployments for the affected services and pages the owning on-call team in PagerDuty if any deploy fails…

- OutputPage owning on-call on failure or error spikePagerDuty
What it does
Closes the loop after a dependency bump merges. It identifies which services were affected by the merged lockfile change, watches their Vercel deployments, and if any deployment errors or post-deploy error rates spike, it pages the on-call owner for that specific service in PagerDuty. This ties a bad upgrade directly to the engineers who can roll it back.
When to use it
Use it when dependency upgrades occasionally break production and the link between "that lockfile PR" and "this incident" is lost in the noise. It makes the blast radius observable at deploy time, not just at review time.
How it works
- 1A pull request that changed a lockfile is merged on GitHub.
- 2The affected services are resolved from the merged dependency delta.
- 3The corresponding Vercel deployments are tracked until they finish.
- 4A branch checks each deployment outcome and error signal.
- 5Healthy deploys post a green status comment back on the merged PR.
- 6Failed or degraded deploys page the owning service's on-call rotation in PagerDuty with the bump details.
