youtube-fetcher-to-markdown

Fetch transcripts from YouTube videos and save as structured Markdown files to ~/yt_transcripts/. Use this skill whenever the user shares a YouTube URL or video ID and wants the transcript, captions, or subtitles extracted. Also triggers when the user wants to take notes on a YouTube video, summarize video content, analyze what was said in a video, or reference YouTube content in their notes — even if they don't explicitly say "transcript." If the user pastes a YouTube link with no other context, default to fetching the transcript.
