Manage the lessons learned registry.
When extracting lessons:
- Review recent mistake patterns, win patterns, and retrospectives
- Identify lessons that are stable (confirmed across 2+ sessions)
- Chart as
lesson-<name> category governance with the lesson text
- Format: LESSON (one sentence), EVIDENCE (which sessions/events), APPLIES TO (agents/tools/workflow)
When listing lessons:
- Search
lesson-* charts
- Present sorted by recency
- Flag any lessons that may be outdated based on recent changes
Lessons should be prescriptive: "Do X because Y" not "X happened once."
