How it runs

The automated pipeline, trigger to output.

  • TriggerScheduled upgrade scan
  • ActionPin one package and run tests in sandboxed shellShell
  • LogicGate: continue only on green test run
  • ActionDeploy Vercel preview of upgrade branchVercelVercel
  • OutputPost preview URL and diff to Slack for approvalSlack

What it does

This agent goes one step beyond green tests: it builds a live Vercel preview of the upgraded app and routes it to Slack so a human can eyeball the running build before any merge request exists.

When to use it

Use it for front-end or full-stack repos where a passing unit suite isn't enough confidence and you want a quick visual smoke check on a real deployment before review.

How it works

  1. 1A schedule kicks off the upgrade scan.
  2. 2The agent pins one outdated package and runs the test suite in a sandboxed shell.
  3. 3A logic gate stops the run on any test failure.
  4. 4On success, it triggers a Vercel preview deployment of the upgrade branch.
  5. 5It posts the preview URL, version diff, and test summary to a Slack channel.
  6. 6The Slack message carries the preview link as the final output, ready for an approver to inspect before the team opens the MR.
