Summary
This is a wrapper around yt-dlp for downloading YouTube videos, extracting transcripts, and pulling metadata without any API costs. It's the tool you reach for when you need actual video files or subtitles on disk, not when you're scraping search results or comments (use Apify for that). The skill includes sensible defaults like automatic output directory structure, URL validation, and filename sanitization. Honestly, if you already know yt-dlp, this just gives you ready-made Python scripts with safe patterns. If you don't, it's a faster way to get started than reading yt-dlp docs. Works completely offline after pip install, no keys to manage.
