What problem does it solve? Choosing consistent styles, color palettes, typography, and UX patterns for web and mobile interfaces is time-consuming and error-prone, especially when reviewing accessibility, animation, and responsive behavior across multiple stacks. ## Core Features & Use Cases - Design System Generation: Run a single CLI query to produce a complete design system (pattern, style, colors, typography, effects) with reasoning rules and anti-patterns, optionally persisted as a MASTER.md plus per-page overrides. - Domain Search: Query 50+ styles, 161 color palettes, 57 font pairings, 161 product types, 99 UX guidelines, and 25 chart types across 10 stacks including React, Next.js, Vue, SwiftUI, Flutter, and Tailwind. - UI Review Checklists: Apply priority-ranked rule categories (accessibility, touch targets, performance, forms, navigation, charts) to audit existing interfaces. - Use Case: When asked to build a fintech dashboard, generate a persisted design system, then search the chart and ux domains to pick accessible chart types and interaction patterns before writing components. ## Quick Start Ask the AI to generate a design system for your product type and then review your page against the accessibility and UX checklist.
