## Complete Workflow Decision Tree

When a user requests video creation, follow this decision tree:

```
User Input
    │
    ├─ Website URL + Keywords (no script)
    │       → Use script-generation skill (optional, for planning)
    │       → Use video-generation skill (music-only Veo video)
    │       → Use upload-to-drive skill
    │
    ├─ Website URL + Keywords + Detailed Script
    │       → Use video-generation skill (Veo B-roll)
    │       → Use heygen-avatar skill (avatar narration)
    │       → Combine video + avatar
    │       → Use upload-to-drive skill
    │
    ├─ Detailed Script Only
    │       → Use heygen-avatar skill (avatar presentation)
    │       → Optionally add Veo B-roll
    │       → Use upload-to-drive skill
    │
    ├─ YouTube/Google Drive URL
    │       → Use shorts-creation skill (6-step workflow)
    │       → Automatically uploads to Drive at end
    │
    └─ Theme/Topic (no specific script)
            → Use script-generation skill first
            → Then proceed based on user preference for video type
```

## Key Principles

1. **Complete Workflows**: Execute end-to-end from input to shareable video
2. **User Input Integration**: Smoothly incorporate URLs, keywords, scripts, themes
3. **Tool Orchestration**: Seamlessly use MCP servers and local tools
4. **Intelligent Defaults**: Provide sensible defaults, but allow customization
5. **Fallback Planning**: Always have a manual path when tools unavailable
6. **Quality Focus**: Optimize every output for professional delivery
7. **Clear Communication**: Keep user informed throughout multi-step processes

---

## Limitations

- **Video Generation**: Veo quality depends on prompt engineering and API availability
- **Avatar Quality**: HeyGen lip-sync accuracy varies with script complexity
- **Transcription**: Whisper accuracy depends on audio quality and language
- **Processing Time**: Large videos and multiple shorts take time to process
- **Storage Limits**: Google Drive has storage quotas (15GB free)
- **API Costs**: Some operations consume API credits
- **Internet Dependency**: Download and upload speeds affect workflow timing

When limitations arise, pivot to fallback workflows and keep user informed.
