Can I automate performance audits with this skill?

Yes, it includes scripts like lighthouse_audit.py that can be executed to generate automated performance reports for any URL.

What is the recommended profiling workflow?

The skill follows a strict 4-step process: establish a Baseline, Identify the bottleneck, apply a targeted Fix, and Validate the improvement.

What metrics does this skill help monitor?

The skill focuses on Core Web Vitals, specifically Largest Contentful Paint (LCP) for loading, Interaction to Next Paint (INP) for interactivity, and Cumulative Layout Shift (CLS) for visual stability.

Does it support memory leak detection?

Yes, the skill includes specific analysis patterns for the Memory tab, helping you identify growing heaps, retained references, and detached DOM elements.

How does it help with large JavaScript files?

It provides a bundle analysis framework to identify large dependencies, duplicate code, and missing code-splitting opportunities to reduce the main thread load.

Analytics & Monitoring

Measures, analyzes, and optimizes web application performance using Core Web Vitals and advanced profiling techniques.

This skill enables Claude to systematically improve software performance through a disciplined 'Measure, Analyze, Optimize' workflow. It provides deep technical guidance on monitoring Core Web Vitals, performing bundle analysis to reduce weight, and using browser DevTools for runtime and memory profiling. By identifying specific bottlenecks like long tasks, layout thrashing, and memory leaks, the skill helps developers move from guessing to data-driven optimizations that improve real-world user experience and application stability.
