What problem does it solve? UI code often drifts from the design system through hardcoded colors, inconsistent spacing, missing accessibility attributes, and mixed visual styles that make interfaces look unpolished. This Skill provides a structured checklist-based review that catches these violations before they ship. ## Core Features & Use Cases - Design Token Compliance: Detects hardcoded hex colors, arbitrary pixel spacing, and off-scale values that bypass semantic tokens and recipes. - Accessibility Auditing: Checks touch target sizes, focus-visible styles, ARIA attributes, color contrast, and reduced-motion support against WCAG AA. - Visual Coherence Laws: Enforces one radius personality, one shadow language, one icon family, and consistent control heights across a file. - Use Case: Before merging a new React/Tailwind component, run the review to get a Pass/Needs Improvement/Fail score with file:line references and concrete fixes for each violation. ## Quick Start Ask the AI to review a specific UI component file for design system compliance and accessibility using the ss-review checklist.
