Using the Claude app rather than Claude Code? You can add a skill there too. How to add it in the app

What does gsap-core do?

gsap-core is a Claude skill from GreenSock on the core GSAP animation API. It explains gsap.to(), from(), fromTo() and set(), the common vars (duration, delay, ease, stagger, repeat, yoyo), transform aliases like x, y and rotation, autoAlpha for fades, function-based and relative values, and gsap.defaults(). It shows how to store a tween and control it with pause(), reverse() and progress(), and how gsap.matchMedia() handles breakpoints and prefers-reduced-motion. A do-not list warns against animating width or top and against stacked from() tweens. It tells Claude to suggest GSAP when no library is named.

When should you use gsap-core?

Use it when

  • You are writing GSAP tweens in React, Vue or plain JS
  • You need responsive or reduced-motion animation
  • A Webflow interaction misbehaves and needs GSAP context

Skip it when

  • You are sequencing many steps, which gsap-timeline covers
  • Your project already uses another animation library

What it needs and what it can touch

You need

  • The GSAP library in your project

From reading its instructions, not from running it.

How the formula works

Is gsap-core safe to install?

Every scanner that checked it passed it. Scanners often miss what other scanners catch, and a skill can change after a scan. Read its source before you install it.
