Overview

/fix-issues - Fix Lighthouse Issues

Apply fixes for Lighthouse audit failures to improve scores.

Steps

  1. Load the most recent Lighthouse audit results
  2. Prioritize issues by impact: high-impact, medium-impact, low-impact
  3. For Performance issues:
    • Add lazy loading to below-the-fold images
    • Optimize image formats and sizes (WebP, AVIF)
    • Add preload hints for critical resources
    • Defer non-critical JavaScript and CSS
  4. For Accessibility issues:
    • Add missing alt text to images
    • Fix color contrast ratios
    • Add ARIA labels to interactive elements
    • Ensure proper heading hierarchy
  5. For Best Practices issues:
    • Fix mixed content (HTTP resources on HTTPS pages)
    • Add security headers (CSP, X-Frame-Options)
    • Update deprecated APIs
  6. For SEO issues:
    • Add missing meta descriptions and titles
    • Fix mobile viewport configuration
    • Add structured data markup
  7. Apply each fix incrementally and verify it resolves the flagged audit
  8. Re-run Lighthouse to measure the improvement
  9. Report: fixes applied, score changes, remaining issues

Rules

  • Fix high-impact issues first for maximum score improvement
  • Do not break existing functionality while fixing audit issues
  • Test visual appearance after applying performance optimizations
  • Verify accessibility fixes with manual keyboard navigation
  • Keep performance optimizations progressive (do not block rendering)
  • Document each fix for team awareness and future maintenance
