Upstream community skill encoding Emil Kowalski's design engineering philosophy: animation decision frameworks, component polish, performance rules, and UI review checklists. Use it case-by-case — for example when reviewing animations or refining interaction details — rather than leaving it always on.
Install from upstream — do not copy the skill file from memory:
npx skills add emilkowalski/skill
Supports Claude Code, Codex, Cursor, and other agents that use the skills CLI. The skill slug is emil-design-eng.
Usage
Invoke when you want design-engineering feedback, for example:
Review the animation and interaction polish on this dropdown component.
For deeper material on motion and interface craft, see animations.dev.
Raw content
Copy into your project — e.g. .instructions.md, .agent.md, or SKILL.md
