Format: - [YYYY-MM-DD] {description} → WORKAROUND: {solution}
Update ~/.ohc/USER.md if:
For each novel reusable pattern:
.ohc/skills/{kebab-name}.mdohc skill promote {name}
If session revealed Cursor-specific learnings:
→ Use /Generate Cursor Rules to create permanent .mdc rules
Write 3-sentence summary to .ohc/state/sessions/{id}/summary.md:
See references/retro-template.md for structured format.
