What does gsap-performance do?
gsap-performance is a Claude skill that helps make GreenSock (GSAP) animations run at a smooth 60fps. It steers Claude to animate transform values like x, y, scale and rotation plus opacity, and away from width, height, top, left, margin and padding. It sets will-change only on elements that move and keeps DOM reads and writes in separate batches. For many elements it prefers stagger over separate tweens with delays, and for mouse followers it uses gsap.quickTo(). ScrollTrigger tips cover pinning only what is needed, small scrub values and debounced ScrollTrigger.refresh() calls. It also asks Claude to kill off-screen and stray tweens.
When should you use gsap-performance?
Use it when
- A scroll animation drops frames
- A mouse follower causes jank
- Hundreds of elements animate at once
Skip it when
- Your animations use only CSS or Framer Motion
- You need to learn GSAP basics first
