Why This Exists

Motion.dev has 10M+ downloads per month. It is the standard for web animations in React, Next.js, Svelte, and Astro. But writing good animations is hard. You need spring physics, GPU-accelerated properties, prefers-reduced-motion support, and 60fps+ performance targets.

This skill gives Claude Code deep knowledge of Motion.dev patterns so it can generate production animation code from natural language. No more copying from docs. No more guessing spring values. Just describe what you want.

Install

Add to your Claude Code skills directory:

# Clone into your skills folder
git clone https://github.com/199-biotechnologies/motion-dev-animations-skill.git ~/.claude/skills/motion-dev-animations

# Or add as a git submodule in your project
git submodule add https://github.com/199-biotechnologies/motion-dev-animations-skill.git .claude/skills/motion-dev-animations

The skill activates automatically when you mention animations, Motion.dev, scroll effects, parallax, hover effects, or interactive UI in your prompts.

Quick Start

Once installed, use natural language with Claude Code:

"Create a hero section with a fade-up entrance animation"
"Add parallax scrolling to this landing page"
"Build a card component with hover lift and shadow effects"
"Implement drag-to-reorder for this list"
"Add a magnetic button effect to the CTA"

Claude Code will clarify your framework, plan the animation strategy, generate the code, and verify performance.

How It Works

The skill follows a four-step workflow:

1. Clarify -- Determines your framework (React 19+, Next.js 15+, Svelte 5+, Astro 4+), animation type, and design goals.
2. Plan -- Selects the right Motion.dev patterns, spring physics, and easing curves for your use case.
3. Implement -- Generates TypeScript/JSX code using GPU-accelerated properties (transform, opacity, filter only). No layout thrashing.
4. Verify -- Checks for 60fps+ performance, prefers-reduced-motion support, keyboard navigation, and bundle size under 50KB.

The skill uses progressive loading. The core instructions are ~2,000 tokens. Examples, API reference, and templates load on-demand only when needed. This means 87% less context consumption compared to loading everything upfront.

Animation Types

Entrance Animations

• Hero Fade Up -- Apple-style fade + slide entrance for landing pages
• Hero Stagger -- Orchestrated title, subtitle, CTA sequence
• Scroll Reveal -- Intersection Observer fade-in on scroll

Scroll Effects

• Parallax Layers -- Multi-speed depth effect with useScroll and useTransform
• Scroll Progress -- Reading progress bar tied to scroll position

Gesture Interactions

• Card Hover -- Lift with shadow using whileHover
• Magnetic Button -- Cursor-following effect for CTAs
• Drag Carousel -- Touch-friendly horizontal slider with drag constraints

Micro-interactions

• Button Press -- Tactile tap feedback with whileTap
• Toggle Switch -- Smooth state transitions with layout animations
• Loading Spinner -- Spring-based loader animation

Layout Animations

• List Reorder -- Drag-to-reorder with FLIP technique
• Accordion -- Smooth expand/collapse with AnimatePresence
• Tab Switch -- Shared layout transitions with layoutId

Performance Standards

Every animation this skill generates meets these targets:

Metric	Target	Method
Frame rate	60fps+ (120fps ideal)	GPU-accelerated transforms only
Bundle size	< 50KB	Tree-shaking, code splitting
Accessibility	Full	prefers-reduced-motion respected
Layout shifts	Zero	No width/height animations
Keyboard support	Full	Focus states, navigation

Framework Support

Framework	Version	Status
React	19+	Full support
Next.js	15+	Full support (App Router)
Svelte	5+	Full support
Astro	4+	Full support
Vue	3+	Use motion-v package
Vanilla JS	ES2020+	Via motion package
