Lighthouse Performance Auditing & Fixes

I'll run comprehensive Lighthouse audits for performance, accessibility, SEO, and best practices, then implement prioritized fixes automatically.

Audit Categories:

  • Performance (Core Web Vitals: LCP, FID, CLS)
  • Accessibility (WCAG compliance)
  • SEO (Search engine optimization)
  • Best Practices (Security, modern standards)
  • PWA (Progressive Web App)

Arguments: $ARGUMENTS - optional: URL to audit (defaults to http://localhost:3000) or mobile/desktop

<think> Lighthouse auditing requires understanding: - Core Web Vitals (LCP, FID, CLS) impact on user experience - Accessibility barriers and WCAG guidelines - SEO best practices and meta tag requirements - Performance optimization opportunities - Progressive enhancement strategies </think>

Token Optimization

Expected range: 300–2,800 tokens (initial), 100 tokens (good scores)

Caching: Caches last audit results in .claude/cache/lighthouse/last-audit.json for 7 days.

Early exit: Returns immediately if all Lighthouse scores are above the threshold.

Patterns used: Grep-before-Read, early exit, Bash for system queries, caching
