Analyze YouTube or local videos for private learning notes: transcript-first summarization, timestamped evidence, authorized keyframe extraction with yt-dlp/ffmpeg, adversarial viewpoint analysis, and original local hand-drawn explainer visuals. Trigger when user asks to summarize, study, extract notes, capture key frames, critique viewpoints, or create visual learning reports from a video.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# youtube-study-note Skill ## Core philosophy Treat a video as a time-indexed evidence source, not just a blob of media. 1. Define the goal first: quick skim, full study note, critique, screenshots, or visual summary. 2. Prefer text timeline over raw visual analysis: subtitles > auto subtitles > local audio transcription > visual sampling. 3. Use screenshots only as evidence for important visual moments, not as decoration. 4. Default the HTML report to **core-content mode**: suppress creator intros, channel promotion, series setup, repeated disclaimers, and other edge context unless the user asks for a complete archive. Lead with the video's actionable core ideas. 5. Translate domain jargon before using it. For technical/finance/trading videos, add plain-language concept cards that explain what each term solves, not just what it is called. When a video is jargon-heavy, generate one built-in imagegen concept illustration per core term and render it inside that term's concept card. Put these concept cards before the overview and route sections so later summaries can use the terms without forcing the reader to guess them first. 6. Separate evidence from interpretation: …

How to install
mdr add wangjs-jacky/jacky-skills/youtube-study-note@sha256:fd31fdbbb70267ffThe line at the top of this page pins the label v0.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
