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.

## Required Reference

Read [references/motion-performance-qa-guide.md](references/motion-performance-qa-guide.md) before making architectural or visible UI changes with this skill.
