What problem does it solve? Diagnosing slow page loads and poor Lighthouse scores requires correlating traces, network requests, and code, which is tedious and error-prone when done manually. This Skill automates the audit workflow so you get prioritized, quantified findings instead of guesswork. ## Core Features & Use Cases - Core Web Vitals Measurement: Captures LCP, INP, CLS, FCP, TBT, and Speed Index via Chrome DevTools performance traces with good/needs-improvement/poor ratings. - Network & Render Analysis: Detects render-blocking resources, network dependency chains, missing preloads, caching issues, and oversized payloads. - Codebase Analysis: Detects your framework and bundler (Webpack, Vite, Next.js, etc.) and flags tree-shaking, polyfill, minification, and dead-code issues. - Use Case: Ask it to audit your staging site; it runs a trace, reports that the hero image delays LCP by 1.2s and a render-blocking script adds 400ms, then recommends specific fixes with estimated savings. ## Quick Start Audit the performance of https://example.com and tell me the top issues affecting my Core Web Vitals.
