🔒 Security Declaration

This skill downloads videos/subtitles from YouTube/Bilibili/Xiaohongshu/Douyin.

It does NOT directly call external LLM APIs - it outputs structured requests for agent processing.

OPENAI_API_KEY and OPENAI_BASE_URL are optional - used by agent, not by this script.

Cookie files are read locally only, never transmitted externally.

No config files written. No secrets stored. No telemetry, no analytics.

Summarization requests are output as structured text for agent/external LLM processing. Script itself makes no direct LLM API calls. Requires yt-dlp, jq, ffmpeg.

Video Summary Skill

Intelligent video summarization for multi-platform content. Supports Bilibili, Xiaohongshu, Douyin, YouTube, and local video files.

What It Does

Auto-detect platform from URL (Bilibili/Xiaohongshu/Douyin/YouTube)
Extract subtitles/transcripts using platform-specific methods
Generate structured summaries with key insights, timestamps, and actionable takeaways
Multi-format output (plain text, JSON, Markdown)
Direct LLM integration — outputs ready-to-use summaries
Automatic cleanup — no temp file leaks

Quick Setup

No API key required to run. This skill extracts video content and outputs structured requests for summarization. The agent (or external tool) handles LLM calls.

# Optional: If you want the agent to call LLM for summarization
export OPENAI_API_KEY="your-api-key-here"
export OPENAI_BASE_URL=https://open.bigmodel.cn/api/paas/v4

# Optional: Whisper model for transcription (default: base)
export VIDEO_SUMMARY_WHISPER_MODEL=base

How it works:

Script extracts video subtitles/transcript
Script outputs a structured summary request (JSON/text)
Agent or external tool calls LLM API with the request
Script does NOT directly call any external APIs

Supported LLM Providers

OpenAI: https://platform.openai.com/api-keys
Zhipu GLM: https://open.bigmodel.cn/
DeepSeek: https://platform.deepseek.com/
Moonshot: https://platform.moonshot.cn/

Just set OPENAI_BASE_URL to the provider's API endpoint.

Cookie Configuration (Optional)

Xiaohongshu and Douyin may need cookies for some videos:

# Set cookie file path
export VIDEO_SUMMARY_COOKIES=/path/to/cookies.txt

# Or use --cookies flag
video-summary "https://xiaohongshu.com/..." --cookies cookies.txt

⚠️ Cookie Security Note:

Cookie files contain session tokens and are sensitive
Only use cookies from your own browser sessions
Do not share cookie files with others
Cookie files are read locally and never transmitted externally by this script

Manual Trigger

If configuration is incomplete, say:

"help me configure video-summary"

Quick Start

Check Dependencies

# Check all required tools
yt-dlp --version && jq --version && ffmpeg -version

# If missing, install
pip install yt-dlp
apt install jq ffmpeg  # or: brew install jq ffmpeg

Basic Usage

# Standard summary
video-summary "https://www.bilibili.com/video/BV1xx411c7mu"

# With chapter segmentation
video-summary "https://www.youtube.com/watch?v=xxxxx" --chapter

# JSON output for programmatic use
video-summary "https://www.xiaohongshu.com/explore/xxxxx" --json

# Subtitle only (no AI summary)
video-summary "https://v.douyin.com/xxxxx" --subtitle

# Save to file
video-summary "https://www.bilibili.com/video/BV1xx" --output summary.md

# Use cookies for restricted content
video-summary "https://www.xiaohongshu.com/explore/xxxxx" --cookies cookies.txt

In OpenClaw Agent

Just say:

"Summarize this video: [URL]"

The agent will automatically:

Detect the platform
Extract video content
Generate a structured summary

Commands Reference

Command	Description
`video-summary "<url>"`	Generate standard summary
`video-summary "<url>" --chapter`	Chapter-by-chapter breakdown
`video-summary "<url>" --subtitle`	Extract raw transcript only
`video-summary "<url>" --json`	Structured JSON output

How It Works

Platform Support Matrix

Platform	Subtitle Extraction	Notes
YouTube	Native CC + auto-generated	Best support
Bilibili	Native CC + backup methods	Requires video ID extraction
Xiaohongshu	Limited (OCR fallback)	No native subtitles, uses transcription
Douyin	Limited (OCR fallback)	Short-form video, may need transcription
Local files	Whisper transcription	Supports mp4, mkv, webm, mp3, etc.

Supported URL Formats

Performance Estimation

Whisper Transcription Time

Video Duration	tiny	base	small	medium
5 min	~30s	~1m	~2m	~4m
15 min	~1.5m	~3m	~6m	~12m
30 min	~3m	~6m	~15m	~30m
60 min	~6m	~12m	~30m	~60m

Notes:

GPU significantly faster (3-10x)
base model recommended for balance
First run downloads model (~150MB for base)

Subtitle Extraction Time

Platform	Time	Notes
YouTube	~5s	Direct subtitle download
Bilibili	~5s	Direct subtitle download
Xiaohongshu	~3m	Requires transcription
Douyin	~2m	Requires transcription

Advanced Configuration

Whisper for Transcription

For platforms without native subtitles (Xiaohongshu, Douyin), install Whisper:

pip install openai-whisper

Then configure:

export VIDEO_SUMMARY_WHISPER_MODEL=base  # tiny, base, small, medium, large

OpenAI API for Summarization

This script does NOT directly call LLM APIs. It outputs structured requests for the agent to process.

If you want the agent to call LLM for summarization, configure:

# Optional: API key for your LLM provider
export OPENAI_API_KEY="your-api-key-here"

# Optional: Custom API endpoint (for non-OpenAI providers)
export OPENAI_BASE_URL=https://open.bigmodel.cn/api/paas/v4  # Zhipu
# export OPENAI_BASE_URL=https://api.deepseek.com/v1        # DeepSeek
# export OPENAI_BASE_URL=https://api.moonshot.cn/v1          # Moonshot

# Optional: Model selection
export OPENAI_MODEL=gpt-4o-mini

Without API key: Script outputs transcript and structured request. Agent handles summarization.

Cookie Configuration for Restricted Content

Some platforms require authentication for certain content:

# Method 1: Command line
video-summary "https://www.xiaohongshu.com/explore/xxxxx" --cookies cookies.txt

# Method 2: Environment variable
export VIDEO_SUMMARY_COOKIES=/path/to/cookies.txt

How to get cookies:

Install browser extension: "Get cookies.txt LOCALLY"
Login to the platform
Export cookies to file

Custom Summary Prompt

Create ~/.video-summary/prompt.txt:

# Summary Template

## Key Insights
- List 3-5 core arguments

## Key Information
- Data, cases, quotes

## Action Items
- Specific actions viewers can take

## Timestamp Navigation
- Key moments with timestamps and descriptions

Output Formats

Standard Output (default)

Environment Variables

Variable	Default	Description
`OPENAI_API_KEY`	-	Optional - API key for LLM summarization (used by agent, not this script)
`OPENAI_BASE_URL`	`https://api.openai.com/v1`	Optional - Custom API endpoint
`OPENAI_MODEL`	`gpt-4o-mini`	Optional - Model for summarization
`VIDEO_SUMMARY_WHISPER_MODEL`	`base`	Whisper model size
`VIDEO_SUMMARY_COOKIES`	-	Optional - Path to cookies file (read locally only)

Troubleshooting

"No subtitles found"

The video may not have subtitles/CC
Try --transcribe to use Whisper
For Xiaohongshu/Douyin, transcription is required

"yt-dlp: command not found"

pip install yt-dlp
# or
brew install yt-dlp

"Missing required dependencies"

# Install all dependencies
pip install yt-dlp
apt install jq ffmpeg  # Ubuntu/Debian
# or
brew install jq ffmpeg  # macOS

"Video too long"

Long videos (>1h) are automatically chunked:

Split into 10-minute segments
Summarize each segment
Merge into final summary

"Failed to fetch video info"

Video may be private or deleted
Try --cookies for restricted content
Region-locked videos may not work

"Rate limited"

Too many requests to platform
Wait a few minutes
Use --cookies for authenticated access
