Emil Kowalski turns UI animation taste into Skills for AI coding agents

Emil Kowalski 发布设计工程师 Skills，让 AI 编码工具具备 UI 动画审美

Emil Kowalski released three design-engineering Skills for Codex, Claude Code, and Cursor. They encode hard rules: no animation on high-frequency actions, keep UI motion under 300ms, animate only transform and opacity, start entrances from scale(0.95) + opacity:0, and respect prefers-reduced-motion. The review-animations Skill outputs a Before/After/Why table; animation-vocabulary turns vague descriptions into professional motion terms. The post doesn't say whether the Skills are open-source or paid.

Why it matters: Emil Kowalski packaged UI animation engineering know-how into AI-usable Skills — a novel angle with concrete substance. But the audience is limited to the frontend/design-engineering crossover, lacking cross-domain resonance, so it lands right at the featured threshold.
