What problem does it solve? Consumer UI code often drifts from the design system: hardcoded hex colors, misused components, missing aria-labels, and re-implemented layout primitives. This Skill systematically audits product UI code (not the design system itself) to catch token leaks, component misuse, geometry bugs, and accessibility gaps before they reach stakeholders. ## Core Features & Use Cases - 7-Dimension Audit: Checks token hygiene, layout primitive consumption, component correctness, mindset adherence, visual geometry, accessibility, and design principle compliance, each with concrete grep patterns and severity rules. - Severity-Triaged Reports: Classifies findings as P0 (must-fix bugs), P1 (batch fixes), P2E (autonomous engineering fixes), or P2H (product decisions requiring user input), with a structured report template. - Visual Audit Gate: Adds a stakeholder-facing visual layer (WCAG contrast, DOM geometry assertions, screenshot review) on top of the code-level audit. - Use Case: Before merging a new checkout feature, run the audit on src/app/features/checkout/ to catch a hardcoded #3b82f6, an icon-only Button missing aria-label, and a hand-rolled empty state that should use the <Empty> component. ## Quick Start Ask the AI to audit a specific UI folder, for example: audit src/app/features/checkout for design system usage violations.
