User says: "session-retro", "retrospective", "retro", "summary"
Steps
- Review the current session:
- What tasks were completed?
- What approaches worked well?
- What failed or took too long?
- Any patterns discovered?
- Write retro to
session-notes.md(append "## Retrospective" section if file exists, or create new) - If any lessons are universal (not project-specific), suggest adding to project CLAUDE.md
- Report summary to user
Rules
- Keep it brief — 5-10 bullet points max
- Focus on actionable insights, not descriptions of what happened
- Don't over-analyze one-off issues
