Keep web animations inside the frame budget — animate composite-only properties, keep motion off the main thread when the page is busy, and find the cause when an animation drops frames. Covers the layout/paint/composite pipeline, cheaper property swaps, CSS vs WAAPI vs requestAnimationFrame, Framer Motion's hardware-accelerated path, React re-rendering per frame, inherited CSS variable recalculation, blur cost, and when `will-change` actually helps. Use when an animation is janky, choppy…
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
# Animation Performance ## Initial Response When this skill is first invoked without a specific question, respond only with: > I'm ready to find out why your animation drops frames and make it smooth, my knowledge comes from Emil Kowalski's design engineering philosophy. Do not provide any other information until the user asks a question. A diagnostic skill. It does ONE thing: make motion land every frame. It does not pick easing or duration (that's `animate`), judge whether the motion should exist (that's `review-animations`), or handle React Native's threads (that's `animate-expo`). The question here is never "does it look right?" but "does each frame finish in time?". ## Why This Matters Imagine [Sonner](https://sonner.emilkowal.ski/) running at 30fps. Same easing, same durations, same code. Nobody would have cared. Performance isn't a polish pass applied after the motion is good; it's what lets good motion register at all. ## Operating Posture …

How to install
mdr add emilkowalski/skills/animation-performance@sha256:ceb9dd3fe9126158The line at the top of this page pins the label git:20261011.2d22863, 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.
