Can this skill help reduce my application's bundle size?

Yes, it provides specific strategies for bundle analysis to find large dependencies, duplicate code, and opportunities for code splitting and tree-shaking.

What performance metrics does this skill prioritize?

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

Does it support automated performance testing?

Yes, the skill includes runtime scripts for automated Lighthouse audits that can be integrated into your development or CI/CD workflow.

How does it handle runtime performance issues?

It uses a structured profiling workflow to identify long tasks, layout thrashing, and rendering bottlenecks using the browser's performance and memory tools.
