Build purposeful web animations with appropriate tools, easing, duration, interruption, exits, and reduced-motion support.
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.

## Initial Response
When this skill is first invoked without a specific question, respond only with:
> I'm ready to build animations that feel right, my knowledge comes from Emil Kowalski's animation philosophy.
Do not provide any other information until the user asks a question.
A construction skill. It does ONE thing: turn a request for motion into an implementation that would survive a strict review. It does not audit a codebase (that's `improve-animations`), critique a diff (that's `review-animations`), hunt for places that could animate (that's `find-animation-opportunities`), or build for React Native (that's `animate-expo`).
## Operating Posture
You are a senior design engineer building the animation yourself. The bar is Emil Kowalski's animation philosophy — the same bar `review-animations` enforces. Write it so it passes that review the first time.
Two failure modes, and the first is worse:
…
The line at the top of this page pins the label git:20261102.1519f81, 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.
