Make code-first motion (an animation that is a program, rendered frame by frame in a headless browser) look directed instead of generic, and check that sampled frames re-render identically. Ships the render contract (every frame a pure function of t, window.renderAt(t), no clocks, timers or unseeded random, pinned libraries, frames 0..N-1), a numbers-not-adjectives prompt template with a living ban list, and a render -> look -> fix loop whose notes name frames. Deterministic core…
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
# motion-lab — directed, reproducible code-first motion An LLM does not output pixels for an animation. It writes a program that draws each frame, and a headless browser records the frames. Three properties follow, and this skill is built to keep them: 1. **A frame is reproducible.** Frame 84 rendered twice is the same image twice. 2. **An edit is cheap.** Change one number and re-render. Nothing is re-rolled. 3. **The agent can check its own work.** It reads stills and a contact sheet, and writes notes against frame numbers. ## The one rule > **Adjectives get defaults. Numbers get direction.** > > The generic look is what the model produces where the prompt left a value open. > "Premium", "cool" and "modern" decide nothing, so the model decides for you: > dark navy space, glow, bloom, particles, a spinning turntable. Every adjective > you replace with a number is a decision you take back. ## Pipeline 1. **Pick the engine and the canvas first.** Changing the canvas later means re-directing every shot. | Piece | Engine | |---|---| | one idea, under 10 s, 2D | plain HTML + CSS / Canvas / SVG | …

How to install
mdr add broomva/skills/motion-lab@sha256:e70117525a8a1d7dThe line at the top of this page pins the label git:20261022.b8dd991, 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.
