Comprehensive quality review covering performance, accessibility, SEO, and best practices across 150+ checks.
Analyzes code and projects across four audit categories: Performance (Core Web Vitals, resource optimization, loading strategy), Accessibility (perceivable, operable, understandable, robust), SEO (crawlability, on-page, technical), and Best Practices (security, standards, UX patterns)
Categorizes findings by severity (Critical, High, Medium, Low) with specific, actionable recommendations and code examples for fixes
Includes pre-deploy checklists, weekly review tasks, and monthly deep-dive guidance for ongoing quality maintenance
Provides detailed guidance on Core Web Vitals thresholds (LCP < 2.5s, INP < 200ms, CLS < 0.1) and WCAG accessibility standards (4.5:1 contrast ratio, keyboard navigation, ARIA usage)
Web quality audit
Comprehensive quality review based on Google Lighthouse audits. Covers Performance, Accessibility, SEO, and Best Practices across 150+ checks.
Lighthouse v13 note (Oct 2025+). Lighthouse has migrated the Performance category from per-opportunity audits to Performance Insight Audits (announcement). Several individual audit names this skill historically referenced — First Meaningful Paint, No Document Write, Uses Passive Event Listeners, Uses Rel Preload — have been removed or merged. The underlying advice is unchanged and still applies; only the report format moved. The CLS-related audits ("layout shifts", "non-composited animations", "unsized images") are now consolidated into a single cls-culprits-insight, and image audits are merged into image-delivery-insight. Treat older Lighthouse JSON output as a superset, not a contradiction.
