The performance skill identifies and resolves web performance bottlenecks through Lighthouse-based audits, prioritizing optimizations by their impact on Core Web Vitals and providing specific code examples. It serves developers and site owners who need to improve page speed, reduce load times, and enhance user experience across loading speed, runtime efficiency, and resource optimization. The skill solves the problem of slow-loading websites by establishing performance budgets, optimizing the critical rendering path, and guiding implementation of techniques like code splitting, asset preloading, and compression.
