SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill helps teams measure, analyze, and optimize web performance by automating profiling and providing actionable insights to reduce load times and improve user experience.

Core Features & Use Cases

  • Lighthouse-based audits to quantify performance scores and surface bottlenecks across LCP, INP, and CLS.
  • Guidance for runtime and memory profiling to diagnose rendering and interactivity issues in web apps.
  • Use Case: When a product page loads slowly in production, run automated profiling to identify the bottlenecks and implement targeted optimizations such as code-splitting or asset optimization.

Quick Start

Use the performance-profiling skill to audit the page at https://example.com and report the scores, bottlenecks, and recommended improvements.

Frequently Asked Questions about performance-profiling

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run automated Lighthouse audits to measure Core Web Vitals for a URL?▼

Automated Lighthouse audits measure Core Web Vitals by invoking Lighthouse via CLI, parsing report JSON, and returning scores for performance, accessibility, best-practices, and SEO. You get a concise summary of bottlenecks across LCP, INP, and CLS.

What is web performance profiling and when do I need it for SPAs and dashboards?▼

Web performance profiling is the process of measuring and analyzing load times to improve user experience. You need it for SPAs and dashboards when diagnosing rendering bottlenecks or interactivity issues in development, CI, or production monitoring.

How do I identify bottlenecks like LCP and CLS issues in a slow-loading product page?▼

To identify bottlenecks like LCP and CLS issues, run automated profiling using Lighthouse audits on the slow-loading product page URL. The parsed report returns performance scores and surfaces actionable bottlenecks for targeted optimizations like code-splitting.

Can I use Lighthouse profiling in CI pipelines and production monitoring?▼

Yes, Lighthouse profiling is applicable to CI pipelines and production monitoring. It invokes Lighthouse via CLI, parses report JSON, and returns scores for performance, accessibility, best-practices, and SEO to identify Core Web Vitals issues.

Does Lighthouse profiling provide guidance for runtime and memory profiling in web apps?▼

Lighthouse profiling provides guidance for runtime and memory profiling to diagnose rendering and interactivity issues in web apps. It quantifies performance scores and surfaces bottlenecks across LCP, INP, and CLS for targeted optimizations.

What's the best way to profile web performance end-to-end without external dependencies?▼

The best way to profile web performance end-to-end is running automated Lighthouse audits via CLI. This approach parses report JSON to return performance, accessibility, best-practices, and SEO scores along with a concise summary of bottlenecks.
