Can I automate performance audits?

Yes, the skill includes instructions for running lighthouse_audit.py scripts to automate performance measurements directly within your development environment.

How does this skill help with Core Web Vitals?

It provides specific targets for LCP, INP, and CLS, along with strategies to optimize each metric through automated measurement and targeted code fixes.

What kind of bundle analysis does it perform?

It identifies issues like large dependencies, duplicate code, and missing code splits, recommending actions like tree shaking and module-specific imports.

How does it help with memory leaks?

It guides Claude to look for patterns like growing heaps and detached DOM nodes using specialized memory analysis principles.

Is this skill only for web applications?

While it focuses on web technologies and browser profiling, the core methodology of measurement and bottleneck identification is applicable to many software optimization tasks.

Analytics & Monitoring

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

This skill empowers Claude to conduct systematic performance audits of web applications by following a rigorous 'Measure, Identify, Fix, Validate' workflow. It provides specialized guidance on optimizing Core Web Vitals like LCP and INP, performing deep bundle analysis to reduce load times, and diagnosing runtime bottlenecks or memory leaks using browser DevTools patterns. By integrating automated Lighthouse audits and specific optimization strategies such as code splitting and lazy loading, it helps developers transform sluggish interfaces into high-performance, production-grade user experiences.
