Module 6 · Section 1 of 8

Something goes wrong. Maybe Claude took an action you didn’t approve. Maybe a deployment broke because of a step that wasn’t in the runbook. Maybe a decision that seemed obvious at the time turned out badly.

The default response is to fix it and move on. The lessons-learned skill is what you run instead. It guides Claude through a structured retrospective — not to assign blame, but to identify what system change would prevent this from happening again — and then implements that change before the session ends.
