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.

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 5.5 | $0.00036 | $0.02259 |
| Sonnet 5.5 | $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 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.
This is a copy
100% identical to gsap-plugins — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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 12-Studio/Tackl (10 stars, last pushed 15d ago), licensed MIT. It adds 91 tokens to every session and 5,648 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to gsap-plugins, differing in 1 line, and is treated as a copy.

react-doctor
Use when finishing a feature, fixing a bug, before committing React code, or when the user types /doctor, asks to scan, triage, or clean up React diagnostics. Covers lint, accessibility, bundle size, architecture. Includes a regression check and a full local-triage workflow that fetches the canonical playbook.
migrate-radix-to-base
Migrates React projects and components from Radix UI to Base UI. Use when asked to migrate from radix, move to base-ui, convert radix primitives, or switch a shadcn project's base library. Handles single components ("migrate accordion") and whole projects.
reskin
Author a NEW skin for the reskinnable-demo app. A skin is a self-contained domain plugin under src/skins/ / that implements the frozen Skin contract (src/shell/skin-contract.ts) to swap the app's entire experience — brand, theme, layout, pages, tools, data, and agent — as a live sales demo. Use when the user says "add…
nextjs-pages-router
Set up tRPC in Next.js Pages Router with createNextApiHandler, createTRPCNext, withTRPC HOC, SSR via ssr option and ssrPrepass, SSG via createServerSideHelpers with getStaticProps, and server-side helpers for getServerSideProps prefetching.
react-query-setup
Set up @trpc/tanstack-react-query with createTRPCContext(), TRPCProvider, useTRPC() hook, queryOptions/mutationOptions factories, query invalidation via queryClient.invalidateQueries with queryFilter, and type inference with inferInput/inferOutput.
non-json-content-types
Handle FormData, file uploads, Blob, Uint8Array, and ReadableStream inputs in tRPC mutations. Use octetInputParser from @trpc/server/http for binary data. Route non-JSON requests with splitLink and isNonJsonSerializable() from @trpc/client. FormData and binary inputs only work with mutations (POST).
