Phase 1: User Profiling (MANDATORY FIRST STEP)

Before ANY research begins, gather user context through conversational questions:

┌─────────────────────────────────────────────────────────────────┐
│  🎯 USER PROFILING QUESTIONS                                    │

│  1. 「你的目标」What do you want to achieve?                    │
│     □ 社交谈资 (Casual conversation)                            │
│     □ 职业转型 (Career transition)                              │
│     □ 投资决策 (Investment decisions)                           │
│     □ 合作洽谈 (Business collaboration)                         │
│     □ 纯粹好奇 (Pure curiosity)                                 │

│  2. 「当前背景」What's your current profession/background?      │
│     (This helps tailor analogies and explanations)              │
│                                                                 │
│  3. 「时间预算」How much time can you invest?                   │
│     □ 30分钟速览 (Quick overview)                               │

└─────────────────────────────────────────────────────────────────┘

Present these questions conversationally, not as a form. Adapt based on context clues in the user's initial request.

Phase 2: Deep Research

Execute comprehensive web research covering:

1. Industry Fundamentals
2. Core business models and value chains
3. Key players (companies, organizations)

4. Market size and growth trends

5. Key Figures & Events

6. Influential people (founders, thought leaders, critics)
7. Historical milestones and turning points

8. Recent news and developments

9. Professional Vocabulary

10. Industry jargon and acronyms
11. Insider phrases and expressions

12. Common misconceptions to avoid

13. Real Cases & Stories

14. Success stories with specific details
15. Notable failures and lessons learned
16. Current controversies or debates

Research Tools:
- Use WebSearch for current information, news, trends
- Use WebFetch for detailed article content

Phase 3: Media Acquisition (MANDATORY - DO NOT SKIP)

⚠️ THIS PHASE IS REQUIRED FOR EVERY EXECUTION

媒体素材是让学习笔记生动有力的关键。必须执行媒体获取流程，但数量和类型根据内容需要灵活调整。

3.1 媒体获取原则

核心原则：根据内容类型选择最合适的获取方式

└─────────────────────────────────────────────────────────────────┘

3.2 媒体数量指南（灵活调整）

不设硬性数量限制，根据内容丰富度和主题特点决定：

3.3 图片获取策略

策略 A：事实性图片 → 优先网络下载

适用场景：
- 人物照片（创始人、CEO、专家、艺术家、导演、演员等）
- 产品图片、公司 Logo、品牌视觉
- 电影剧照、海报、专辑封面
- 新闻事件配图、历史照片
- 实物图片（食物、设备、建筑等）

获取方式：

# 方式 1: 使用 media-downloader（需要 API Key）
python ~/.claude/skills/media-downloader/media_cli.py image "关键词" -n 数量 -o 输出目录

# 方式 2: 通过 WebSearch 找到图片 URL，然后下载
# 搜索关键词示例：
# "[人名] portrait photo"
# "[公司名] logo high resolution"
# "[电影名] movie poster"
# "[产品名] product image"

搜索关键词模板：

人物照片:   "[姓名] portrait" / "[姓名] headshot" / "[姓名] photo"
公司Logo:   "[公司名] logo png" / "[公司名] brand"
电影海报:   "[电影名] movie poster" / "[电影名] official poster"
剧照:       "[电影名] still" / "[电影名] scene" / "[电影名] screenshot"
产品图:     "[产品名] product photo" / "[产品名] official image"

策略 B：概念性图片 → 使用 AI 生成

适用场景：
- 行业价值链、生态系统图
- 业务流程图、工作流程
- 抽象概念的视觉化表达
- 关系图、层级图
- 氛围图、风格示意图
- 找不到合适真实图片时的备选

使用 zimage-skill 生成：

MODELSCOPE_API_KEY="your-key" python3 ~/.claude/skills/zimage-skill/generate.py "prompt" "output.jpg"

Prompt 模板：

# 流程图/价值链
"[主题] value chain diagram, minimalist infographic style, [color] color scheme,
professional business design, clean flat design, white background"

# 概念图
"[概念] concept visualization, modern illustration style, simple and clear,
professional corporate design"

# 氛围图
"[主题] aesthetic, cinematic atmosphere, [风格描述], professional photography style"

# 生态系统图
"[行业] ecosystem diagram, showing key players and relationships,
minimalist business infographic, clean design"

策略 C：备选方案

当以上方式都失败时：
- 提供外部链接：[查看图片](url)
- 使用文字描述代替
- 使用 Mermaid 图表（适用于流程图）

3.4 视频获取策略

使用 media-downloader 下载 YouTube 视频：

python ~/.claude/skills/media-downloader/media_cli.py youtube "URL" -o "输出目录" --end 120

视频类型与搜索关键词：

视频要求：
- 时长：根据内容价值灵活裁剪（建议 60-180 秒）
- 内容：与主题直接相关
- 质量：至少 720p

3.5 媒体文件命名规范

人物照片:   person-[姓名拼音或英文].jpg
概念图:     diagram-[描述].jpg
剧照/海报:  poster-[作品名].jpg / still-[作品名].jpg
案例图:     case-[案例名].jpg
产品图:     product-[产品名].jpg
视频:       video-[主题].mp4

3.6 媒体嵌入格式 (Obsidian)

图片: ![[media/filename.jpg]]
视频: ![[media/filename.mp4]]
带说明: ![[media/filename.jpg|这是图片说明]]

3.7 媒体获取检查清单

在完成媒体获取后，确认：

• [ ] 所有提到的关键人物都有对应图片（真实照片优先）
• [ ] 核心概念有视觉化表达（AI 生成或真实图片）
• [ ] 至少有 1 个相关视频片段
• [ ] 图片和视频数量与内容丰富度匹配
• [ ] 所有媒体文件已下载到本地 media 文件夹
• [ ] 文件命名清晰规范

Phase 4: Ask Save Path (MANDATORY)

⚠️ 在生成内容之前，必须询问用户保存路径

使用 AskUserQuestion 工具询问用户：

问题: "请告诉我你想把学习笔记保存到哪里？"

选项:
1. 当前目录 (Current directory)
2. 桌面 (Desktop)
3. 自定义路径 (Custom path)

如果用户选择自定义路径:
- 等待用户输入完整路径
- 验证路径是否存在，不存在则创建

默认文件结构:

[用户指定路径]/
├── [主题]速成指南.md          # 主文档
└── media/                      # 媒体文件夹
    ├── diagram-*.jpg
    ├── person-*.jpg
    ├── case-*.jpg
    └── video-*.mp4
