Workflow Guide
When user provides a Douyin URL:
- Identify URL type (video, profile, music, live, hashtag)
- Ensure cookies are available (almost always needed)
- Run the appropriate yt-dlp command with
--cookies-from-browser - Parse JSON and present formatted Markdown
- Highlight music/sound info (trending sounds are key on Douyin)
- Offer follow-ups: "Want me to analyze this creator's content strategy?" / "Extract subtitles?"
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
- Cookies required: Prompt user to authenticate with
--cookies-from-browser chrome - Video unavailable: "This video has been deleted or is not accessible."
- Region restricted: "Douyin content is primarily available in mainland China. A China IP or proxy may be needed."
- Live offline: "This live stream is not currently active."
- Short link resolution: yt-dlp handles v.douyin.com links automatically
Notes
- Douyin is the Chinese version of TikTok. Content and APIs are separate.
- Cookies are almost always required for stable access.
- Douyin is primarily accessible from mainland China IPs. Access from outside China may require a proxy.
- Music/sound trends on Douyin often precede TikTok trends by weeks.
- Live stream data is only available while the stream is active.
