What it does

This skill gives an AI agent detailed reference knowledge of the gsap.utils helper functions from the GSAP animation library. Once installed, when you ask for animation code, the agent knows how to use helpers such as clamp (keep a value within limits), mapRange (convert one number range to another, such as scroll position to rotation), snap (round to a grid), and random (pick random values), including their function forms for reuse. The skill itself contains only documentation and examples; it does not run any code or contact the internet.

Great for

  • Front-end developers using GSAP who want accurate helper usage in generated code
  • Designers or creative coders building scroll or mouse-driven animations who need values mapped or randomized
  • Teams reviewing existing GSAP code for correct use of gsap.utils functions

Skip it if

  • People who do not use GSAP; the skill only covers the gsap.utils library and will not help with other animation tools
  • Tasks needing GSAP plugins such as ScrollTrigger or CustomEase, which the skill refers to other skills for, so they may be only partly covered

Try asking

  • “Use gsap.utils.mapRange to convert my scroll progress into a rotation angle for this GSAP tween”
  • “Write a GSAP mousemove handler that clamps the x position of a box between 0 and 300”
  • “Snap my draggable element to a 20px grid using gsap.utils.snap”
  • “Randomize the colours of these list items with gsap.utils.random from an array”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Name the helper you want (for example clamp or mapRange) in your request so the agent loads this skill reliably.
  • Check the generated numbers against the examples in the skill, and test animations in a browser, since the skill is reference material and does not verify output.
  • Install the related gsap-core, gsap-timeline and gsap-scrolltrigger skills alongside this one for full animation work.
