Operations

1. Note Metadata (Video Notes)

Extract title, description, engagement stats from a video note.

yt-dlp --dump-json --skip-download --cookies-from-browser chrome \
  "https://www.xiaohongshu.com/explore/NOTE_ID"

Key JSON fields:

| Field | JSON path | |-------|-----------| | Title | .title | | Description | .description | | Author | .uploader | | Upload date | .upload_date (YYYYMMDD → YYYY-MM-DD) | | Views | .view_count | | Likes | .like_count | | Comments | .comment_count | | Duration | .duration (video only) | | Thumbnail | .thumbnail | | Tags | .tags[] |

2. Image Note Extraction

For image-based notes (图文笔记), use gallery-dl:

gallery-dl --dump-json --cookies-from-browser chrome \
  "https://www.xiaohongshu.com/explore/NOTE_ID"

Returns JSON with image URLs, caption, and metadata. Image notes typically contain 1-9 images with text overlay.

3. User Profile Analysis

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

For all content types (images + videos):

gallery-dl --dump-json --range 1-20 \
  --cookies-from-browser chrome \
  "https://www.xiaohongshu.com/user/profile/USER_ID"

Output format: Table with columns: #, Date, Type (Image/Video), Title (first 40 chars), Likes.

4. Content by Topic / Tag

Xiaohongshu topic pages:

gallery-dl --dump-json --range 1-20 \
  --cookies-from-browser chrome \
  "https://www.xiaohongshu.com/search_result?keyword=KEYWORD"

URL Patterns

| Pattern | Type | |---------|------| | xiaohongshu.com/explore/NOTE_ID | Single note | | xiaohongshu.com/discovery/item/NOTE_ID | Single note (alt) | | xhslink.com/SHORTCODE | Short link | | xiaohongshu.com/user/profile/USER_ID | User profile |

Number Formatting

• = 10000 → {n/10000:.1f}万

• = 1000 → {n/1000:.1f}千

• Otherwise → raw number

Workflow Guide

When user provides a Xiaohongshu URL:

1. Identify URL type (note, profile, search)
2. Determine content type (image note or video note)
3. Use yt-dlp for video notes, gallery-dl for image notes
4. Authenticate with --cookies-from-browser (almost always needed)
5. Parse JSON and present formatted Markdown
6. Offer follow-ups: "Want me to analyze this creator's content pattern?"

When user asks to download media:

• This skill focuses on content extraction and analysis, not downloading.
• If the user explicitly asks for download help, suggest using yt-dlp/gallery-dl directly or an online tool like snapvee.com.

Error Handling

• Login required: Prompt user to authenticate via cookies
• Note unavailable: "This note has been deleted or is only visible to the author."
• Rate limited: "Xiaohongshu rate limit reached. Wait and retry."
• Image note with yt-dlp: Switch to gallery-dl for image content
• Short link: May need manual resolution or direct browser cookie access

Notes

• Xiaohongshu has two main content types: 图文笔记 (image notes) and 视频笔记 (video notes).
• Most content requires authentication. Cookies are essential.
• gallery-dl handles image notes better; yt-dlp handles video notes better.
• Content may be region-restricted (primarily available in mainland China).
• Short links (xhslink.com) may require cookie-authenticated resolution.
