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
# BB Video Videos drawn in code: HTML + CSS / SVG / canvas frames, rendered frame by frame in Chrome, sound synthesized in code, assembled with ffmpeg. Every frame is the pure function `renderFrame(t)`, so any frame can be rendered on its own and every render is identical. Relative paths in this file are relative to this skill's folder. ## One choice: the style The style is the **only** thing the user picks. It decides how the video looks, moves and sounds — never what it says. If the user names a style, use it; otherwise recommend one from the topic or product and say why in the storyboard. When the user says "try another style", redo the same content in the new style. | Style | Look | Best for | Explainer | Promo | |---|---|---|---|---| | `whiteboard` hand-drawn whiteboard | Drawing on an infinite whiteboard while explaining, camera moves, cartoon characters | Problem walkthroughs, derivations, phenomena, stories that need characters | ✓ | ✓ | | `riso` risograph | Magazine pages with spot-color overprint, halftone, misregistration; page turns by drum roll | Everyday trivia, psychology, news, finance, data, food, vocabulary | ✓ | ✓ | …

How to install
mdr add bubblebrainbb/bb-video/bb-video@sha256:9d7203f8090cc311The line at the top of this page pins the label git:20261104.261988a, 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.
