What problem does it solve? Teams shipping frontend interfaces often lack a systematic way to catch accessibility violations, performance regressions, theming inconsistencies, and responsive design failures before users do. This Skill runs a structured diagnostic scan and produces a prioritized audit report instead of ad-hoc fixes. ## Core Features & Use Cases - Multi-Dimensional Diagnostic Scan: Checks accessibility (contrast, ARIA, keyboard navigation, semantic HTML), performance (layout thrashing, expensive animations, bundle size), theming (hard-coded colors, dark mode), and responsive design (touch targets, breakpoints). - Anti-Pattern Detection: Flags AI-generated design tells such as gradient text, glassmorphism, generic fonts, and nested cards against the frontend-design skill's guidelines. - Severity-Rated Report Generation: Produces an executive summary, findings grouped by Critical/High/Medium/Low severity with WCAG references, systemic pattern analysis, and a prioritized remediation plan mapped to fix commands. - Use Case: Before a product launch, run the audit on your checkout flow to receive a report listing a missing focus indicator on the payment button (Critical, WCAG A), hard-coded hex colors in 15 components (High), and touch targets under 44px on mobile (Medium), each with a recommended fix command. ## Quick Start Ask the assistant to audit the checkout page for accessibility, performance, theming, and responsive design issues and generate a severity-rated report.
