YouTube Video Info

Get video details and generate content summary.

Quick Start

/mk-youtube-get-info <URL> [browser]

Examples

# Basic usage (auto-detects cookies if needed)

# Specify browser for cookie authentication
/mk-youtube-get-info https://www.youtube.com/watch?v=dQw4w9WgXcQ chrome

How it Works

1. Execute: {baseDir}/scripts/info.sh "<URL>"
2. Parse JSON to get video metadata
3. Try to get subtitles for summarization
4. Generate summary based on subtitle content
5. If no subtitles, display video info only

Centralized Metadata Store

This skill automatically saves video metadata to /tmp/monkey_knowledge/youtube/meta/{YYYYMMDD}__{video_id}.meta.json. This metadata can be accessed by downstream skills (caption, audio, transcribe, summary) to include video information in their outputs.

Content Summary

(Generated from subtitle analysis)

• Key point 1
• Key point 2
• ...

Notes

• Uses system yt-dlp/jq if available, otherwise auto-downloads on first run
• Cookie Fallback: If initial request fails, automatically retries with browser cookies (auto-detects Chrome, Firefox, Safari, Edge, Brave)
• Browser Parameter: Optionally specify chrome, firefox, safari, edge, or brave to use specific browser cookies

Next Step

After obtaining video info, determine the summarization path based on subtitle availability:

• If has_subtitles: true or has_auto_captions: true: Invoke /mk-youtube-get-caption to download subtitles
• If both are false: Invoke /mk-youtube-get-audio to download audio for transcription

To generate a complete summary, always follow the full pipeline — do NOT skip directly to summarization without first obtaining a transcript through one of the above paths.
