Turn a YouTube video into a markdown note in the user's notes vault — a note good enough to replace watching the video. Use when given a YouTube link to save, summarise, take notes on, or "make a note from", even if the user doesn't say "note" — any YouTube link with intent to capture it. Pulls the transcript in the video's original language, distils it with timestamps, searches the vault for notes the video connects to, writes a personalized "why this matters" section, and gives an honest watch/skip verdict.
