Use: /emil-design-eng

Curated external (hand-maintained)

Composed compose-external-wave-4 using authoring SSOT (docs/src/authoring/skills/emil-design-eng.mdx) + research. Do not run wagents docs generate on this file (HAND-MAINTAINED sentinel). Run external-skill-auditor before using in production or promoting.

What It Does

Design engineering skill distilled from Emil Kowalski (animations.dev) articles and course. Encodes philosophy on UI polish, component design, animation decisions (timing <300ms, custom easing), perceived performance, invisible details that make interfaces feel great. Uses before/after tables and concrete rules for reviews.

Harness Coverage

Targets verified harnesses: antigravity, claude-code, codex, crush, cursor, gemini-cli, github-copilot, grok, opencode.

Portable multi-harness install command:

npx skills add emilkowalski/skill --skill emil-design-eng -y -g -a antigravity claude-code codex crush cursor gemini-cli github-copilot grok opencode
