Workflow Guide
When user provides a TikTok URL:
- Identify URL type (video, profile, sound, hashtag)
- Run the appropriate yt-dlp command
- Parse JSON and present formatted Markdown
- Highlight sound/music info (important for TikTok content strategy)
- Offer follow-ups: "Want me to analyze this creator's posting pattern?" / "Check trending sounds?"
When user asks to download a video:
- This skill focuses on content extraction and analysis, not downloading.
- If the user explicitly asks for download help, suggest using yt-dlp directly or an online tool like snapvee.com.
Error Handling
- yt-dlp not found: Print install commands
- Video removed: "This video has been removed by the creator or TikTok."
- Private account: "This account is private."
- Region restricted: "This video is not available in your region."
- Short link: yt-dlp auto-resolves vm.tiktok.com links
- Rate limited: "TikTok rate limit reached. Wait and retry."
Notes
- TikTok may require cookies for some content:
--cookies-from-browser chrome - Short links (vm.tiktok.com) are automatically resolved by yt-dlp.
- Sound/music metadata is key for TikTok content analysis — trending sounds drive discovery.
- Comments extraction may not work on all videos due to TikTok API restrictions.
