What problem does it solve? AI-generated interfaces often look generic and template-like, with ad-hoc colors, mismatched radii, emoji icons, and janky animations. This Skill enforces a design-system-first workflow so every page, dashboard, form, modal, and game overlay looks intentional and consistent. ## Core Features & Use Cases - Design tokens first: Defines palette, radii, fonts, spacing, and motion as CSS variables in Tailwind v4 @theme, banning raw hex and arbitrary values in JSX. - Quantified quality rubric: Enforces limits like 3-5 colors, 2 font families, 44px tap targets, mobile-first layouts, and contrast-safe foreground/background pairing. - Anti-slop rules and motion recipes: Blocks gradient blobs, emoji icons, and placeholder images, and provides tokenized animation patterns (modals, menus, number pop-ins, icon swaps) via shadcn/ui and Radix primitives. - Use Case: When restyling a game's start screen and HUD, apply the overlay guidance to build a readable DOM layer over the canvas with concentric radii, staggered text reveals, and reduced-motion-safe transitions. ## Quick Start Use the design-ui skill to redesign this landing page with proper design tokens, typography, and motion so it looks polished instead of generic.
