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.

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 | $0.00052 | $0.01832 |
| Opus 5 | $0.00026 | $0.00916 |
| Sonnet 5 | $0.00010 | $0.00366 |
| Haiku 4.5 | $0.00005 | $0.00183 |
Grade A, and why
animation-motion-design 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 5d 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.

Animation & Motion Design
Patterns for building performant, accessible animations using Motion (formerly Framer Motion, 18M+ weekly npm downloads) and the View Transitions API (cross-browser support in 2026). Covers layout animations, gesture interactions, exit transitions, micro-interactions, and motion accessibility.
Quick Reference
| Rule | File | Impact | When to Use |
|---|---|---|---|
| Layout Animations | rules/motion-layout.md |
HIGH | Shared layout transitions, FLIP animations, layoutId |
| Gesture Interactions | rules/motion-gestures.md |
HIGH | Drag, hover, tap with spring physics |
| Exit Animations | rules/motion-exit.md |
HIGH | AnimatePresence, unmount transitions |
| View Transitions API | rules/view-transitions-api.md |
HIGH | Page navigation, cross-document transitions |
| Motion Accessibility | rules/motion-accessibility.md |
CRITICAL | prefers-reduced-motion, cognitive load |
| Motion Performance | rules/motion-performance.md |
HIGH | 60fps, GPU compositing, layout thrash |
Total: 6 rules across 3 categories
Decision Table — Motion vs View Transitions API
| Scenario | Recommendation | Why |
|---|---|---|
| Component mount/unmount | Motion | AnimatePresence handles lifecycle |
| Page navigation transitions | View Transitions API | Built-in browser support, works with any router |
| Complex interruptible animations | Motion | Spring physics, gesture interruption |
| Simple crossfade between pages | View Transitions API | Zero JS bundle cost |
| Drag/reorder interactions | Motion | drag prop with layout animations |
| Shared element across routes | View Transitions API | viewTransitionName CSS property |
| Scroll-triggered animations | Motion | useInView, useScroll hooks |
| Multi-step orchestrated sequences | Motion | staggerChildren, variants |
Quick Start
Motion — Component Animation
import { motion, AnimatePresence } from "motion/react"
const fadeInUp = {
initial: { opacity: 0, y: 20 },
animate: { opacity: 1, y: 0 },
exit: { opacity: 0, y: -10 },
transition: { type: "spring", stiffness: 300, damping: 24 },
}
function Card({ item }: { item: Item }) {
return (
<motion.div {...fadeInUp} layout layoutId={item.id}>
{item.content}
</motion.div>
)
}
function CardList({ items }: { items: Item[] }) {
return (
<AnimatePresence mode="wait">
{items.map((item) => (
<Card key={item.id} item={item} />
))}
</AnimatePresence>
)
}

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.

animation-motion-design is a skill published in the GitHub repository yonatangross/orchestkit (231 stars, last pushed yesterday), licensed MIT. It adds 52 tokens to every session and 1,832 once invoked, about $0.0003 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 2026-09-03.
Other skills, from other repositories
animation-system-architect
Design performant animation systems with Framer Motion, GSAP, View Transitions API, and spring physics. Activate on: page transitions, micro-interactions, scroll animations, layout animations, spring physics. NOT for: CSS-only hover effects (use css-in-js-architect), video/canvas rendering (use creative-coding-expert).
motion-advanced
Advanced motion patterns for React / Next.js — drag & drop, gestures, text animations, SVG path drawing, custom hooks, imperative sequences (useAnimate), loaders, and the full API decision tree. Requires motion-foundations. Use when building drag and drop, gestures, text or SVG animation, or imperative animation…
motion-craft
Use when an interface moves and the movement has to feel right — durations and easing, what must never animate, fixing motion that reads sluggish, cheap or janky, and reduced-motion. Web and native. NOT the visual system (that is design), NOT the graded critique (that is design-loop).
emil-design-skills
Use when collection of 8 design engineering skills by Emil Kowalski (Vercel, Linear) — animation standards, UI craft, Apple design principles, library selection, and prototyping. Based on years of production experience. Use when the user asks about UI polish, animation decisions, or wants to audit/improve interface…
motion-dev
Use when React animation library — spring physics, gesture animations, layout animations, scroll effects, SVG path drawing. Successor to Framer Motion. Use when building UI animations, micro-interactions, page transitions, shared element transitions, parallax effects.
apple-design
Apple's fluid-interface craft on the web: spring damping and response, velocity handoff, momentum projection on a flick, rubber-banding at a boundary, interruptible motion the user can grab mid-flight, translucent materials and backdrop blur, letter-spacing and leading by size. Use for iOS-grade feel, sheets and drag.
