YouTube Video Analyzer — Multimodal

This skill performs deep analysis of YouTube videos through both information channels:

• Audio channel: Transcript with timestamps (what is SAID)
• Visual channel: Frame extraction + image analysis (what is SHOWN)

Most YouTube skills only extract transcripts. This skill closes the gap by synchronizing visual frames with spoken content, enabling accurate step-by-step guides where "click the blue button" is matched with the actual screenshot showing which button.
