Ui Animation

This is the skill to pull in when you're adding motion to buttons, building a drawer, or reviewing someone's animation code. It covers spring physics, gesture handling, clip-path reveals, and the full stack from CSS transitions to framer-motion. The decision framework is pragmatic: never animate keyboard actions, keep exits fast, and respect that a polished button press matters as much as a fancy modal. The reference files go deep on performance traps like the CSS variables recalc issue and when WAAPI beats keyframes. If you've ever shipped an animation that felt slightly off or wondered why your drag gesture janks on mobile, this will save you the debugging time.

UI Animation

IS: designing, implementing, reviewing, debugging UI motion (springs, gestures, drag, easing, CSS transitions, keyframes, Motion), sweeping an interface for the moments that would genuinely benefit from motion, measuring motion from a recording (extract frames, track, fit curves) to emit code plus a handoff spec, naming a described motion effect (reverse-lookup vocabulary), and gating sparse interface sound.
IS NOT: choosing overall visual direction, palettes, or typography (use ui-design Direction mode), auditing a whole page's UI quality (use ui-design Audit mode), or named text-effect specs (use the external animate-text skill where installed).
