$ npx skills add jeonck/skill-hubakimov121-hub/watch
| Watches any video by URL (YouTube, Loom, a Zoom recording, a direct mp4) — not just the transcript, but what's actually SHOWN on screen. Frames are pulled by scene change (ffmpeg scene detection), not on a timer, so it doesn't miss graphics, demos, edits or b-roll. Audio: subtitles via yt-dlp first, Whisper as a fallback. Use this when the user writes /watch <url> or asks to "watch this video", "go through this recording/call/ lecture", "what's shown on screen". Triggers: /watch, watch this vi
