description	Generate quiz questions from saved Cornell explanation cues (concept + Q&A history). Use when the host invokes "请用 extra-quiz-generation skill 根据以下概念列表生成附加题" with a JSON list of concepts and their Q&A histories. Writes the result to disk using the Write tool.

Extra Quiz Generation Skill

Generate single-choice quiz questions from the user's saved Cornell explanation cues. Each cue represents a concept the user highlighted and asked about while reading.

Input

The host's prompt will contain a JSON list of concepts:

[
  {
    "concept": "位置编码",
    "qa_history": [
      {"q": "位置编码", "a": "位置编码给每个 token 加一个位置向量..."},
      {"q": "为什么用正弦余弦？", "a": "因为正弦余弦函数具有周期性和连续性..."}
    ]
  }
]

Each entry has:

• concept — the user's highlighted term (concept name)
• qa_history — Q&A pairs starting with the initial explanation (Q0/A0), then follow-up Q&As

文件格式（写入 output_file）

用 Write 工具将以下 JSON 数组写入 prompt 中指定的 output_file 路径：

[
  {
    "id": "extra_1",
    "qtype": "single",
    "question": "关于「位置编码」，以下哪项描述最准确？",
    "options": [
      {"label": "A", "text": "位置编码给每个 token 加一个位置向量，让 Transformer 能区分序列顺序"},
      {"label": "B", "text": "这是一个合理的错误选项（基于常见误解）"},
      {"label": "C", "text": "另一个合理的错误选项"},
      {"label": "D", "text": "第三个合理的错误选项"}
    ],
    "correct": "A",
    "weak_concepts": ["位置编码"]
  }
]

Rules

1. Based on Q&A history for each concept: Use the actual explanation content from qa_history to construct Option A (the correct answer). The initial explanation (Q0/A0) and follow-up Q&As provide rich material.

2. Distractor quality: Options B/C/D must be plausible but incorrect. Draw from:

   • Common misconceptions about this concept
   • Confusion with related concepts in the same domain
   • Partially correct statements with a key error Do NOT use generic distractors like "这是一种数据压缩算法".

3. One question per concept: Generate exactly one question for each concept in the input list. Do not skip any.

4. Question phrasing: The question stem should be specific to the concept. Vary the phrasing:

   • "关于「{concept}」，以下哪项描述最准确？"
   • "以下关于「{concept}」的说法，正确的是？"
   • "对于「{concept}」，下列理解正确的是？"

5. 题型: Only "qtype": "single" (single choice). correct is a single string like "A".

6. weak_concepts: Always include the concept name.

7. id format: extra_1, extra_2, etc. — sequential starting from 1.
