Make a short animated film by writing the drawing code yourself: every frame a pure function of time, rendered headlessly to MP4. Covers storyboarding with a per-shot timing sheet of viewer 'reads', blocking key poses as stills, the contact-sheet / frame-strip / crop review loop, and the hand-painted character kit JohnHeibel/ClaudeAnimationBase (p5.js + p5.brush, the Clawd mascot, 31 emotions). Use for 'animate', 'make a cartoon', 'animated short', 'motion graphic', 'Clawd video', 'p5…
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
# Animating with code
You write the drawing; a headless browser (or PIL, cairo, ffmpeg) renders it. The
method below comes from the ClaudeAnimationBase kit's guide and holds for any
renderer. The kit itself is the fastest route to a hand-painted character short.
Before building, name the route and why (Oskar's standing steer, memory 06886186):
the kit, a CSS/HTML page captured frame by frame, a pure ffmpeg filtergraph, or
PIL/cairo frames.
## The contract: frames are pure functions of t
- A shot is `fn(t)`. Same `t`, same pixels. No counters, no state carried between
frames, no integrated physics, no unseeded random. Then frames can
render out of order, split across parallel workers, and resume after a crash.
- Stable per-object values come from a hash of an index. Deliberate wobble
("boil") comes from a seed that changes on a fixed clock (the kit uses 12 Hz,
each drawing held two frames).
- Reseed per element. A moving element consumes a variable amount of randomness;
without its own seed it shifts the stream for everything drawn after it and
the still parts jitter every frame.

How to install
mdr add oaustegard/claude-skills/animating-with-code@sha256:e4d5fa681bcf526cThe 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.
