Can I use this for automated performance testing?

Yes, the skill includes guidance on using runtime scripts for automated Lighthouse audits and integrating profiling tools into your CI/CD pipeline.

What techniques does it recommend for bundle optimization?

It focuses on identifying large dependencies, deduplicating code, implementing route-based code splitting, and ensuring effective tree shaking to minimize JavaScript execution time.

How do I identify runtime bottlenecks using this skill?

The skill provides patterns for analyzing the DevTools Performance and Memory tabs to find long tasks, layout thrashing, and detached DOM elements that cause memory leaks.

How does this skill help with Core Web Vitals?

It provides specific targets and measurement strategies for Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS) to ensure your site meets Google's 'Good' thresholds.
