  --extractor-args "tiktok:comment_count=20" \
  "https://www.tiktok.com/@user/video/VIDEO_ID"

Parse .comments[] for .author, .text, .like_count. Sort by likes descending.

5. Hashtag / Challenge

• Otherwise → raw number

Workflow Guide

When user provides a TikTok URL:

1. Identify URL type (video, profile, sound, hashtag)
2. Run the appropriate yt-dlp command
3. Parse JSON and present formatted Markdown
4. Highlight sound/music info (important for TikTok content strategy)
5. 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.
