SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the complexity of diagnosing web performance bottlenecks by automating the collection and analysis of Core Web Vitals and network dependency chains.

Core Features & Use Cases

  • Performance Auditing: Measures LCP, INP, CLS, and other critical metrics using Chrome DevTools.
  • Network Analysis: Identifies render-blocking resources and inefficient network dependency chains.
  • Accessibility & Codebase Review: Provides snapshots of accessibility gaps and identifies optimization opportunities in modern frontend frameworks like Vite, Next.js, and Astro.

FAQPage Schema
How do I audit Core Web Vitals like LCP, INP, and CLS for my web application?

You can audit Core Web Vitals like LCP, INP, and CLS by executing performance traces and network audits. This skill automates the collection of these metrics using Chrome DevTools to diagnose web performance bottlenecks.

How do I identify render-blocking resources and inefficient network dependency chains?

To identify render-blocking resources and inefficient network dependency chains, run a network analysis. This skill executes network audits via the chrome-devtools MCP server to pinpoint bottlenecks slowing down your modern web application.

Do I need the chrome-devtools MCP server configured to run a web performance audit?

Yes, you need the chrome-devtools MCP server configured to run a web performance audit. The skill requires this server to be set up for browser interaction and retrieving the trace data needed to measure Core Web Vitals.

Can I analyze web performance and accessibility gaps in Next.js, Vite, or Astro projects?

Yes, you can analyze web performance and accessibility gaps in Next.js, Vite, or Astro projects. The skill reviews modern frontend frameworks to provide snapshots of accessibility issues and identify optimization opportunities.

What is the best way to diagnose web performance bottlenecks and render-blocking resources?

The best way to diagnose web performance bottlenecks and render-blocking resources is automating collection with Chrome DevTools. This skill analyzes network dependency chains and measures critical metrics to find optimization opportunities.
