Was macht ui-animation?
Creates, reviews, and debugs UI motion and animation implementations. Covers springs, gestures, drag interactions, clip-path reveals, easing curves, timing, CSS transition recipes, and animation review. Use when designing, implementing, or reviewing motion, CSS transitions, keyframes, framer-motion, spring animations, or asking "add animations to", "make this feel smooth", "review my animations", "should this animate", "add a swipe gesture", or "add a transition". For recreating motion from a screen recording or video, use reverse-engineer-animation; for overall visual direction and styling, use ui-design; for named text-effect specs (typewriter, line reveal, kinetic builds), use animate-text.
