About the project

gsap-skills is a collection of official AI-agent skills that explain how to use GSAP, a JavaScript animation platform for creating timelines, tweens, and effects such as scroll-driven and path-based motion. It helps coding agents build GSAP animations in vanilla JavaScript and frameworks including React, Vue, and Svelte while following recommended API and performance practices. The catalogue contains the project's skills, instructions, and plugin.

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gsap-plugins scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

GSAP Plugins

When to Use This Skill

Apply when using or reviewing code that uses GSAP plugins: registering plugins, scroll-to, flip/FLIP animations, draggable elements, SVG (DrawSVG, MorphSVG, MotionPath), text (SplitText, ScrambleText), physics, easing plugins (CustomEase, EasePack, CustomWiggle, CustomBounce), or GSDevTools. ScrollTrigger has its own skill (gsap-scrolltrigger).

Related skills: For core tweens use gsap-core; for ScrollTrigger use gsap-scrolltrigger; for React use gsap-react.

Licensing & Install (important)

Every GSAP plugin is free, including for commercial use. Since Webflow's acquisition of GSAP, Club GSAP is no longer a paid tier and no plugin requires a membership, license key, or auth token — this includes formerly Club-only plugins (SplitText, MorphSVG, etc.).

  • ✅ Install everything from the public gsap npm package: npm install gsap. All plugins are included — import them as gsap/SplitText, gsap/MorphSVGPlugin, etc.
  • ❌ Do not generate an .npmrc with a GreenSock auth token, suggest the private npm.greensock.com registry, or tell users to sign up for Club GSAP to access a plugin. Those instructions are outdated.

Registering Plugins

Register each plugin once so GSAP (and bundlers) know to include it. Use gsap.registerPlugin() with every plugin used in the project:

import gsap from "gsap";
import { ScrollToPlugin } from "gsap/ScrollToPlugin";
import { Flip } from "gsap/Flip";
import { Draggable } from "gsap/Draggable";

gsap.registerPlugin(ScrollToPlugin, Flip, Draggable);
  • ✅ Register before using the plugin in any tween or API call.
  • ✅ In React, register at top level or once in the app (e.g. before first useGSAP); do not register inside a component that re-renders. useGSAP is a plugin that needs to be registered before use.

Scroll

ScrollToPlugin

Animates scroll position (window or a scrollable element). Use for “scroll to element” or “scroll to position” without ScrollTrigger.
