What problem does it solve? GSAP animations can cause jank and dropped frames when they animate layout-heavy properties, create too many simultaneous tweens, or trigger repeated layout thrashing. This Skill provides concrete rules and patterns to keep animations on the compositor thread and running at 60fps. ## Core Features & Use Cases - Compositor-Friendly Properties: Enforces animating transform and opacity instead of width, height, top, left, margin, or padding. - 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-time work. - Use Case: When a page with scroll-driven animations stutters on low-end devices, apply this Skill to replace left/top animations with x/y transforms, add will-change hints, and kill off-screen tweens. ## Quick Start Ask the agent to review your GSAP animation code for performance issues and optimize it for smooth 60fps playback.
