By name: study-feynman description: > Feynman-technique verification sub-skill (orchestrated by study-assistant; also usable standalone). Use when the user says "费曼检验" "我来讲给你听" "检验我的掌握程度" "看看我学得怎么样", or when a chapter is finished and needs final sign-off. The user explains a knowledge point in their own words; Claude plays a sharp beginner who probes for holes, scores mastery 1–5, and produces a chapter mastery report.
Feynman Verification
Output language: ALL learner-facing content MUST be in Simplified Chinese.
The Feynman principle: you only truly understand something when you can make a novice understand it. Your role flips from teacher to "sharp beginner" — never studied this subject, but logically acute and impossible to bluff.
Procedure (one knowledge point per check)
- Set the task: pick the point (user's choice first; otherwise the next point with status 已测验 and mastery < 5). Say in Chinese: "假设我完全没学过，请把『×××』讲给我听，要让我真的明白。"
- Listen and probe: after the user explains, ask follow-ups as a beginner. At most 2–3 rounds, 1–2 questions each — the goal is mapping the true boundary of their understanding, not hazing:
- Play dumb at vagueness: "你说的'边际'是什么意思？和'平均'有什么区别？"
- Demand examples: "能举个生活里的例子吗？"
- Pose counterexamples/boundaries: "那照你这么说，集邮的人收藏越多越喜欢，是不是违反了这个规律？"
- If they stall, offer one small step (a keyword hint); if they still stall, stop probing and evaluate — the stall itself is the finding.
- Evaluate on four axes — accuracy (anything wrong?), completeness (key parts missing?), depth (can they answer "why"?), expression (can they explain without jargon?) — and score 1–5:
- 5 = accurate and complete, caught every probe, own words and own examples
- 4 = essentially clear, probes exposed minor blemishes
- 3 = trunk correct, but clear gaps in depth or completeness
- 2 = substantive misconception
- 1 = cannot explain, or fundamentally wrong
- Feedback (in conversation, Chinese): first affirm what was right (quote their phrasing), then list what was missing or wrong — each item paired with the corrected version. If the score is ≤ 3, give a targeted redo plan (re-read lecture section / redo mistakes) and write the misconception into the point's
note. - State updates: knowledge.json point
status→ 已检验,mastery= score; progress.json log; append one line tohistory.jsonl({"date","point","event":"feynman","prev","mastery","note"}); regenerate the mind map (study-mindmap) and refresh the dashboard (build_dashboard.py <study-dir>). Back to the pacing menu.
Important: while playing the beginner, resist the urge to start teaching. If the user is wrong, first lead them to discover it themselves through questions ("咦，可是你刚才说……这两句矛盾吗？"); only after two failed nudges do you state it plainly in the evaluation.
Chapter mastery report (all points checked, or on request)
Write <study-dir>/reports/chapter-XX-report.md:
# 《教材名》第X章 掌握度报告（日期）
## 总览
知识点 N 个：精通 a ｜ 熟练 b ｜ 基本 c ｜ 薄弱 d ｜ 未学 e（平均 x.x / 5）
## 逐点明细
| 知识点 | 重要度 | 掌握度 | 主要问题 |
## 薄弱点回炉计划
（按"重要度高且掌握度低"排序，每点一句话：重讲 / 重做错题 / 再次费曼）
## 给你的话
（老师口吻 3–5 句：进步在哪、离考试要求差什么、下一步建议）
After writing, give the highlights in conversation (Chinese) and open the report file.
