概要
Next.js Performance is a specialized Claude Code skill designed to audit and improve the speed of React-based web applications. It provides expert guidance for implementing core framework features like automatic image optimization, self-hosted fonts, and code splitting via dynamic imports. By focusing on critical metrics such as Cumulative Layout Shift (CLS) and Largest Contentful Paint (LCP), the skill helps developers implement sophisticated caching strategies and bundle optimizations that result in faster load times, reduced server strain, and superior user experiences.
