How it works
- 1Copy the install prompt and paste it into your agent.
- 2Your agent runs mo doctor to check Node.js, FFmpeg and Chrome, and tells you how to install anything missing.
- 3Give it your material. It renders an MP4 on your computer, and you ask for changes in plain words.
Paste into Claude Code, Codex, Cursor or any agent that supports skills.

All it takes
No API keyThis is all it needs
- A document, article or script
Dependencies
Node.js 22+, FFmpeg, Chrome. No API keys.
Before it starts, your agent runs mo doctor to check Node.js, FFmpeg and Chrome and tells you how to install anything missing; if this skill needs more (such as whisper for captions), its instructions say so.
Example prompt
Use the explainer-director skill to make a 45-second explainer for students about why we have seasons.
Style prompt (Claude Motion or Opus 5.5)
Make a 45-second 16:9 explainer for [audience, e.g for [who will watch, e.g. curious people with no background in this]. 12-year-olds] about [the question, e.g. why we have seasons]. Show the thing itself moving, not bullet points; check every fact against [a textbook or source] and keep the source on screen. Start with the question (or the common wrong answer), land the idea on the music's lift, end on one takeaway sentence held 2 seconds. Use only the facts in the source I give below; don't change a word or number. End on the idea in one line, held for 3 seconds.
Nothing to install: paste this into Claude Motion (Team or Enterprise) or give it to Opus 5.5 for a similar look. The result changes from run to run; the skill works from your own material and renders on your computer.
