Workflow Guide

When user provides a Douyin URL:

1. 1. Identify URL type (video, profile, music, live, hashtag)
2. Ensure cookies are available (almost always needed)
3. Run the appropriate yt-dlp command with INLINECODE28
4. Parse JSON and present formatted Markdown
5. Highlight music/sound info (trending sounds are key on Douyin)
6. 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 INLINECODE29
• 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.
