When User Provides Video URL

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
