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.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 20 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.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00091 | $0.05648 |
| Opus 5 | $0.00046 | $0.02824 |
| Sonnet 5 | $0.00018 | $0.01130 |
| Haiku 4.5 | $0.00009 | $0.00565 |
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 10d 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
gsapnpm package:npm install gsap. All plugins are included — import them asgsap/SplitText,gsap/MorphSVGPlugin, etc. - ❌ Do not generate an
.npmrcwith a GreenSock auth token, suggest the privatenpm.greensock.comregistry, 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.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

gsap-plugins is a skill published in the GitHub repository greensock/gsap-skills (15,082 stars, last pushed 1mo ago), licensed MIT. It adds 91 tokens to every session and 5,648 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
