hard-case
Explain a "hard case" the AI just solved so the vibe coder truly understands it. Use right after fixing a tricky bug, a confusing error, something that needed several attempts, or problems involving async/timing/memory/CORS/permissions/cache/library versions, or when the user asks "why did that fix it?", "what did you just change?", "explain this case". Invoke directly for a deep dive into the latest hard case (add save to keep it in LEARNING_NOTES.md).
