name	motion-performance-qa
description	Run motion performance QA for websites and apps. Use after adding Motion, GSAP, Lenis, scroll scenes, page transitions, hover states, carousels, WebGL sync, observers, timers, RAF loops, or any animation-heavy UI to catch jank, layout shift, leaks, cleanup bugs, reduced-motion gaps, and mobile issues.

Motion Performance QA

Use This Skill

Use this skill for audit animation performance, cleanup, accessibility, and jank.

Operating Contract

1. Inspect the existing project before changing code.
2. Identify the motion stack, scroll behavior, component lifecycle, reduced-motion handling, and available verification commands.
3. Keep motion purposeful: clarify sequence, focus, depth, tactility, or product understanding.
4. Follow existing project conventions unless a change clearly improves the result.
5. Run available checks and visually inspect responsive/reduced-motion output when the change affects UI.
