What problem does it solve? UI code often drifts from design system rules through hardcoded colors, inconsistent spacing, missing accessibility attributes, and mixed visual styles. This Skill provides a structured checklist-based review that catches these violations before they reach production. ## Core Features & Use Cases - Design Token Compliance: Detects hardcoded hex colors, arbitrary pixel spacing, and non-standard shadows or border radii in Tailwind-based components. - Accessibility Auditing: Checks touch target sizes, focus-visible styles, ARIA attributes, color contrast ratios, and reduced-motion support against WCAG AA. - Visual Coherence Analysis: Enforces one-choice-per-axis rules for radius, accent color, icon family, shadows, and control heights to eliminate the mixed-style look. - Use Case: A developer finishes a new settings page in React and Tailwind. Running this review flags a hardcoded #3B82F6 color, a 20px padding violation, and missing aria-labels, returning concrete fixes with file and line references. ## Quick Start Review the UI code in src/components/SettingsPanel.tsx for design system compliance, accessibility, and visual consistency.
