Lighthouse Performance Audit

Run Lighthouse audits and get actionable fixes for Core Web Vitals — LCP, INP, and CLS. Analyzes performance scores, identifies bottlenecks, and generates specific code changes to improve page speed.

This skill interprets Lighthouse audit results and translates them into concrete code changes. It identifies render-blocking resources, oversized images, layout shifts, slow server response times, and unused JavaScript. Provides prioritized fixes with estimated impact.

When to use

Use when your Lighthouse score drops, Core Web Vitals fail in Search Console, pages feel slow, or before launching a new page to ensure it meets performance budgets.
