Use this skill to choose motion tools by purpose, not hype.
Routing
- CSS transitions: hover/focus states, small fades, transforms, simple menus.
- Motion: React component animation, layout transitions, presence, gestures, small scroll reveals.
- GSAP: precise timelines, pinned scroll scenes, split text, SVG paths, complex choreography.
- Lenis: smooth scroll feel when the project can support it and anchor/modal behavior is handled.
- Lottie: exported vector motion when file weight and accessibility are acceptable.
- Three.js/R3F: real 3D product/scene work, not decoration.
- No dependency: static content where motion would distract or harm performance.
Motion Requirements
Define:
- purpose: reveal, continuity, depth, state, tactility, narrative, or product explanation
- trigger: load, hover, focus, click, route, scroll, drag, or viewport
- duration/easing
- reduced-motion fallback
- cleanup/unmount behavior
- performance risks
Avoid
- animation because the page is otherwise generic
- scroll hijacking
- motion that hides content
- parallax that causes nausea or jank
- WebGL scenes that are blank on mobile

Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
Improves the quality of images, especially screenshots, by enhancing resolution, sharpness, and clarity. Perfect for preparing images for presentations, documentation, or social media posts.
Create and edit JSON Canvas files (.canvas) with nodes, edges, groups, and connections. Use when working with .canvas files, creating visual canvases, mind maps, flowcharts, or when the user mentions Canvas files in Obsidian.
Publish Markdown articles to X (Twitter) Articles editor with proper formatting.

Teaches the AI to design like a high-end agency. Defines the exact fonts, spacing, shadows, card structures, and animations that make a website feel expensive. Blocks all the common defaults that make AI designs look cheap or generic.
Lightweight WSI tile extraction and preprocessing. Use for basic slide processing tissue detection, tile extraction, stain normalization for H&E images. Best for simple pipelines, dataset preparation, quick tile-based analysis. For advanced spatial proteomics, multiplexed imaging, or deep learning pipelines use pathml.
