xiaohongshu-research-kit

Extract and analyze Xiaohongshu (Little Red Book) content using yt-dlp and gallery-dl. Supports note metadata, image/video extraction, user profile analysis,...

Security Scan

The skill's requests and instructions line up with its stated purpose (extracting Xiaohongshu content via yt-dlp and gallery-dl); nothing in the bundle asks for unrelated credentials or installs unexpected code, but the approach requires access to browser cookies which is sensitive and worth understanding before use.

Purpose & Capability

Name/description claim to extract Xiaohongshu content and the SKILL.md consistently instructs use of yt-dlp and gallery-dl to do exactly that. No unrelated environment variables, binaries, or install steps are required. The clawhub.json metadata (homepage/support_url) is consistent with a research/extraction toolkit.

Instruction Scope

Instructions stay on-topic (identify URL type, choose yt-dlp for video notes, gallery-dl for image notes, parse JSON). The only notable scope matter: the instructions rely on --cookies-from-browser to access authenticated content, which requires the tools to read browser cookies. The SKILL.md does not instruct any broad file-system reads or sending data to unexpected endpoints, aside from referencing snapvee.com for download guidance.

Install Mechanism

Instruction-only skill with no install spec and no code files — lowest-risk distribution. Prerequisites are typical (yt-dlp, gallery-dl) and the doc shows how to install them via brew/pip; there are no remote archive downloads or custom installers in the skill bundle.

Credentials

The skill does not request environment variables or credentials in the bundle, which is proportionate. However, its recommended workflow depends on extracting browser cookies (via --cookies-from-browser), which gives the extracting tool access to session/authentication data. That is necessary for the stated purpose but is sensitive — users should understand the implications before running those commands in shared or untrusted environments.

Persistence & Privilege

The skill does not request elevated persistence (always is false), does not modify other skills or system-wide settings, and contains no install-time hooks. Autonomous invocation is allowed (platform default) but is not combined with other red flags here.

Assessment

This skill appears to do what it claims: it guides using local yt-dlp and gallery-dl to extract Xiaohongshu notes and profiles. Before using it, ensure you: (1) run yt-dlp/gallery-dl locally from trusted installs (brew/pip) rather than executing untrusted bundles; (2) avoid pasting raw browser cookie strings into chats — prefer letting yt-dlp/gallery-dl read cookies locally (and only on a machine you control); (3) be aware that cookie access can expose authenticated session tokens, so do not run these commands on shared CI or untrusted hosts; (4) respect Xiaohongshu's terms of service and copyright when downloading or storing media. If you need stronger assurance, ask the publisher for the project repository code to audit or run the commands in an isolated VM/container.

Extract structured data from Xiaohongshu (小红书) notes, profiles, and content for research. Powered by yt-dlp and gallery-dl locally — no API key required.

Version: 1.0.0 Prerequisites: yt-dlp >= 2024.01.01, gallery-dl >= 1.26.0

Prerequisites

# macOS
brew install yt-dlp gallery-dl

# pip
pip install yt-dlp gallery-dl

# Verify
yt-dlp --version && gallery-dl --version

Authentication

Xiaohongshu requires cookies for most content. Export browser cookies:

yt-dlp --cookies-from-browser chrome "URL"
gallery-dl --cookies-from-browser chrome "URL"

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.
