Which specific metrics does the skill track?

It focuses on industry-standard Core Web Vitals, including Largest Contentful Paint (LCP) for loading, Interaction to Next Paint (INP) for interactivity, and Cumulative Layout Shift (CLS) for visual stability.

What tools does this skill utilize?

It guides the use of Lighthouse, Bundle Analyzers, and Chrome DevTools (Performance, Memory, and Network tabs) to gather data-driven insights.

Does it help with memory leak detection?

Yes, it provides specific analysis patterns for the Memory tab to identify growing heaps, retained references, and detached DOM elements.

How does this skill help improve web performance?

It provides a structured workflow to measure current performance, identify specific bottlenecks like large bundles or long tasks, and implement targeted fixes.

Can I automate performance testing with this skill?

Yes, the skill includes scripts for automated Lighthouse audits that can be executed during development or integrated into CI/CD pipelines.
