Emilkowalski Motion Agent Skill

| Motion-design follow-up skill inspired by Emil Kowalski's animation guidance. Use after an interface exists to add tasteful micro-interactions, state transitions, and page motion with product-grade restraint.

Emil Kowalski Motion Follow-Up

Use this skill after a design artifact already exists. The goal is to make the interface feel alive without turning it into a motion demo.

Workflow

Inspect the current HTML, component, or selected page element before adding animation.
Pick the smallest set of motion moments that clarify state or hierarchy:
entry reveal for the primary content
hover / active feedback for important controls
transition between UI states
scroll reveal only when it helps the story
Prefer transform and opacity. Avoid animating layout properties such as top, left, width, or height.
Use one motion language across the artifact. Do not mix unrelated easings, durations, or physics.
Add prefers-reduced-motion fallbacks for any automatic or scroll-linked motion.
Keep copy, data, and layout intent intact unless the user explicitly asks for a redesign.

Motion Rules

Default UI transitions should feel quick and useful: 140-220ms for most controls.
Larger page reveals can be slower, but must not block reading.
Avoid endless decorative loops unless they communicate status or progress.
Do not add custom cursors, noisy particle effects, or motion that competes with content.
Stagger only small groups. Long staggered lists make interfaces feel slow.

Implementation Notes

For plain HTML, CSS keyframes and small JavaScript observers are enough.
For React or framework code, use the local stack already present in the repo.
If GSAP is available and the motion needs sequencing, pair this with gsap-core, gsap-timeline, or gsap-scrolltrigger.
Always clean up observers, timers, and animation instances.

Canvas Design

by anthropics

vendor ×16

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. Use when user wants to publish a Markdown file/URL to X Articles, or mentions "publish to X", "post article to Twitter", "X article", or wants help with X Premium article publishing.

High End Visual Design

by lornshrimp

×3

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.
