πŸ“– About This Skill

name: video-summary version: 1.6.4 description: "Video summarization for Bilibili, Xiaohongshu, Douyin, and YouTube. Extract insights from video content through transcription and summarization."

πŸ”’ 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.

metadata: openclaw: requires: bins: ["yt-dlp", "jq", "ffmpeg", "ffprobe", "bc"] credentials: - name: "OPENAI_API_KEY" required: false description: "API key for LLM summarization (optional, script outputs request for agent processing)" - name: "OPENAI_BASE_URL" required: false description: "Custom API endpoint (e.g., for Zhipu, DeepSeek)" - name: "VIDEO_SUMMARY_COOKIES" required: false description: "Path to cookies file for restricted video content" behavior: networkAccess: indirect description: "Downloads videos/subtitles from video platforms using yt-dlp. 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. Optional: VIDEO_SUMMARY_WHISPER_MODEL, VIDEO_SUMMARY_COOKIES, OPENAI_BASE_URL, OPENAI_MODEL."

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 β€” outputs ready-to-use summaries
  • Automatic cleanup β€” 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: 1. Script extracts video subtitles/transcript 2. Script outputs a structured summary request (JSON/text) 3. Agent or external tool calls LLM API with the request 4. 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: 1. Detect the platform 2. Extract video content 3. Generate a structured summary

    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

    YouTube:

  • https://www.youtube.com/watch?v=xxxxx
  • https://youtu.be/xxxxx

    • Bilibili:

    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:

    1. Install browser extension: "Get cookies.txt LOCALLY" 2. Login to the platform 3. 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
    •

    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
