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.
