# Lecture Notes Enhancement ## Shared narrative rules Read and follow [the shared narrative and evidence rules](../shared/narrative-and-evidence.md). Keep process notes and defensive source disclaimers out of the lecture notes; state source limitations only when they affect the explained concept. ## Overview Systematic process for cross-referencing recordings, PPTs, and existing notes to identify gaps and enhance lecture notes with narrative-first writing. Uses parallel subagents for efficiency. ## When to Use **Use when:** - Enhancing existing lecture notes (讲义.md) with course recordings and PPTs - Course has multiple source materials (records/, extracted/, existing notes) - Need systematic gap identification and content supplementation - Following md-report-writer narrative style (narrative flow before technical content) **Don't use when:** - Creating lecture notes from scratch (use brainstorming + writing-plans instead) - Simple formatting or proofreading (use simplify skill instead) - Single source material only (direct editing is sufficient) ## Nature of Source Materials Each source type has distinct role and limitations: **Slides (PPT extracted/) — Simplified outline only.** Contain key formulas and section outlines — the final results, not the path to them. No detailed derivations, intermediate steps, or physical intuition. Treat slides as a *what* checklist, not the full content. **Recordings (records/) — Full content with caveats.** Contain detailed deriva
