          你是一位专业的教育内容设计师。请为以下课题设计一个结构化的课程大纲。

          课题: {{topic}}
          难度: {{difficulty}}
          场景数量: {{scene_count}}

          请生成一个 JSON 格式的大纲，包含以下结构：
          {
            "title": "课程标题",
            "description": "课程简介",
            "outline": {
              "items": [
                {"title": "章节1标题", "description": "章节1描述"},
                {"title": "章节2标题", "description": "章节2描述"}
              ]
            }
          }
        input:
          topic: ${inputs.topic}
          difficulty: ${inputs.difficulty}
          scene_count: ${inputs.scene_count}
        json_mode: true
        temperature: 0.7
        max_tokens: 2000

    # Step 2: 并行生成场景
    - id: generate_scenes
      description: 为每个大纲章节生成互动场景
      action:
        type: parallel
        each: ${steps.generate_outline.output.outline.items}
        max_workers: 4
        step:
          id: scene_item
          action:
            type: llm_generate
            template: |
              为以下课程章节生成一个互动教学场景：

              课题: ${inputs.topic}
              章节: {{item.title}}
              章节描述: {{item.description}}
              难度: ${inputs.difficulty}

              生成 JSON 格式的场景内容：
              {
                "title": "场景标题",
                "content": "场景内容描述",
                "interaction": {
                  "type": "quiz|discussion|demonstration",
                  "prompt": "互动提示",
                  "options": ["选项1", "选项2"] (如果是 quiz)
                },
                "key_points": ["要点1", "要点2", "要点3"]
              }
            input:
              item: ${item}
              index: ${index}
            json_mode: true
            temperature: 0.8
            max_tokens: 1500

    # Step 3: 生成课后测验
    - id: generate_quiz
      description: 根据场景内容生成测验题
      action:
        type: llm_generate
        template: |
          基于以下课程场景生成一套课后测验：

          课题: ${inputs.topic}
          场景数量: ${steps.generate_scenes.output | length}

          生成 5 道选择题的 JSON 格式测验：
          {
            "questions": [
              {
                "question": "问题内容",
                "options": ["A选项", "B选项", "C选项", "D选项"],
                "correct": 0,
                "explanation": "答案解释"
              }
            ]
          }
        input:
          topic: ${inputs.topic}
          scene_count: ${steps.generate_scenes.output | length}
        json_mode: true
        temperature: 0.6
        max_tokens: 2000

            "scenes": ${steps.generate_scenes.output},
            "quiz": ${steps.generate_quiz.output}
