Operations

1. Video Metadata

Extract title, creator, engagement stats from a single video.

yt-dlp --dump-json --skip-download --cookies-from-browser chrome \
  "https://www.douyin.com/video/VIDEO_ID"

Key JSON fields:

Field	JSON path
Title / Caption	`.title` / `.description`
Creator	`.uploader`
Creator ID	`.uploader_id`
Upload date	`.upload_date` (YYYYMMDD → YYYY-MM-DD)
Duration	`.duration` (seconds)
Views	`.view_count`
Likes	`.like_count` (点赞)
Comments	`.comment_count`
Shares	`.repost_count` (转发)

Music author	`.artist`
Thumbnail	`.thumbnail`

Short links:

yt-dlp --dump-json --skip-download --cookies-from-browser chrome \
  "https://v.douyin.com/SHORTCODE/"

yt-dlp auto-resolves v.douyin.com short links.

2. User Profile / Video Feed

Extract recent videos from a creator's profile.

yt-dlp --flat-playlist --dump-json --playlist-end 20 \
  --cookies-from-browser chrome \
  "https://www.douyin.com/user/USER_SEC_UID"

Output is one JSON per line. Parse for .title, .upload_date, .view_count, .like_count, .duration.

Output format: Table with columns: #, Date, Title (first 40 chars), Duration, Views, Likes.

3. Subtitles / Captions

Some Douyin videos have embedded subtitles:

# List available subtitles
yt-dlp --list-subs --skip-download --cookies-from-browser chrome \
  "https://www.douyin.com/video/VIDEO_ID"

# Download subtitles
yt-dlp --skip-download --write-sub --write-auto-sub \
  --sub-lang zh --sub-format vtt --convert-subs srt \
  --cookies-from-browser chrome \
  -o "/tmp/douyin-%(id)s.%(ext)s" \
  "https://www.douyin.com/video/VIDEO_ID"

After download, read .srt and clean:

Remove sequence numbers

Output format: [HH:MM:SS] subtitle text

  --cookies-from-browser chrome \
  "https://www.douyin.com/music/MUSIC_ID"

URL Patterns

Pattern	Type
`douyin.com/video/ID`	Single video
`v.douyin.com/SHORTCODE/`	Short link (auto-resolves)
`douyin.com/user/SEC_UID`	User profile
`douyin.com/music/ID`	Music/sound page
`douyin.com/hashtag/ID`	Hashtag page
`live.douyin.com/ROOM_ID`	Live stream

Number Formatting

= 10000 → {n/10000:.1f}万
= 1000 → {n/1000:.1f}千
Otherwise → raw number

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

Cookies are almost always required for stable access.
Douyin is primarily accessible from mainland China IPs. Access from outside China may require a proxy.
