This is a comprehensive web performance auditor built around Google's PageSpeed Insights methodology. It walks you through achieving 90+ scores across Performance, Accessibility, Best Practices, and SEO by identifying specific issues in your code. You get concrete fixes for common problems like unoptimized images, render-blocking resources, layout shifts, and bloated JavaScript bundles, complete with before and after code examples. The skill covers both lab data from Lighthouse and real user field data from CrUX, with clear thresholds for Core Web Vitals like LCP, CLS, and INP. It's thorough enough to use as a reference guide when you're stuck on why your site scores poorly, and the solutions are practical rather than theoretical.
