Production Deploy

This skill encodes the pre-deployment discipline that separates teams who ship confidently from teams who ship and pray. Every checklist item here exists because someone skipped it and caused an outage. The patterns are opinionated and battle-tested — this is not a deployment tutorial, it is a deployment gate.

If you cannot check every box, you are not ready to deploy. Partial deploys are how you get partial outages.

1. Pre-Deployment Checklist

Run through this before every production deploy. No exceptions, no shortcuts, no "we'll check it in staging." Print this out and check the boxes with a pen if that is what it takes.
