emilkowalski / skills

emil-design-eng is the core skill — it encodes Emil Kowalski's own rules on animation timing, easing, and the other small details that separate a polished interface from a mediocre one. review-animations applies that same standard to review existing animation code and defaults to rejecting it; approval has to be earned. animation-vocabulary goes the other direction: it's a reverse-lookup glossary for turning a vague description like "the iOS rubber-band scroll" into the correct technical term, so you can ask an AI or a designer for what you actually want.

All three come from one person's stated experience at Vercel and Linear, not from a broader survey of animation practice, and the package says so itself. That's useful if you want an agent to stop picking ease-in where ease-out belongs and to justify its choices against a specific, named point of view — and less useful if you want broader design-system or non-animation UI guidance, which this package doesn't attempt.
