Emil's Nine Design-Engineering Skills

The main skill handles the small decisions a brief rarely names but an interface always reveals: an enter animation wants ease-out rather than a sluggish ease-in; some surfaces need a translucent shadow rather than a hard border. Eight focused companions build an animation, review existing motion, turn a codebase audit into executable plans, find genuine motion opportunities, translate vague feelings into animation vocabulary, distil web principles from WWDC design talks, stop agents hand-rolling available components, and build several UI variants inside a switcher. The author draws the boundary clearly: AI amplifies domain expertise; it does not replace learning design or code.
