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.
Films it made
All it takes
No API keyAny one of these is enough
- A website or app
- Photos and images
- Video or a recording
- 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 shorts-director skill to make a 25-second vertical short explaining this fact, with its sources on screen.
Style prompt (Claude Motion or Opus 5.5)
Make a 25-second 9:16 short for TikTok, Reels and Shorts about [the one point] for [who will watch, e.g. people scrolling TikTok and Reels]. Open on the question it answers, readable on the first frame. Use only the facts and numbers I give below, with their sources on screen. End on the point in one line, held for 2 seconds. Show the thing itself (a map, a chart, the numbers), one new line every one to two seconds, every line inside the middle of the frame (clear of the captions and buttons), readable without sound. Land the answer on the music's lift and end on the one sentence, held 2 seconds. Point: [one sentence] Facts: [each with its source]
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.
