## Workflow

### When User Provides Video URL

1. Extract URL from user's input using `extract_urls.py`
2. Confirm with user what action to take:
   - Download video
   - Extract audio
   - Show video info
3. Execute appropriate script based on user's choice
4. Notify user of success/failure and file location

### When Auto-detecting URLs

1. Scan conversation text with `extract_urls.py` (can process stdin)
2. If video URLs found, ask user: "I found video URLs in this conversation. Would you like me to download them?"
3. If yes, proceed with download workflow
4. If no, continue with conversation

### Handling Multiple URLs

- For single URL: Direct download
- For multiple URLs: Ask user if they want to download all or select specific ones
- Provide option to download as playlist if URLs are from the same source

## Quality and Format Selection

When user doesn't specify preferences:
- Default to best available quality
- For audio: Default to MP3 at 192kbps

When options needed:
```bash
# Ask user for quality preference if not specified
# Options: best (default), 1080p, 720p, 480p, audio

# Ask for format if extracting audio
# Options: mp3 (default), m4a, opus, flac, wav
```
