What problem does it solve? GSAP animations can cause jank, dropped frames, and layout thrashing when they animate layout-heavy properties or create excessive tweens. This Skill provides concrete rules for keeping animations on the compositor thread and maintaining smooth 60fps rendering. ## Core Features & Use Cases - Compositor-Friendly Properties: Guides you to animate transform and opacity instead of width, height, top, or left to avoid layout and paint costs. - Efficient Update Patterns: Recommends gsap.quickTo() for frequently updated properties like mouse followers, and stagger instead of many manual tweens. - ScrollTrigger Tuning: Covers pin promotion, scrub values, and debounced ScrollTrigger.refresh() calls to reduce scroll-related work. - Use Case: When a user reports a laggy scroll-driven animation or a janky mouse-follower effect, apply these rules to replace layout-triggering properties with transforms and consolidate tweens. ## Quick Start Review my GSAP animation code and optimize it for smooth 60fps performance.
