Automates performance testing and Core Web Vitals enforcement to ensure high-speed frontend delivery.
This skill acts as a mandatory quality gate (Gate 6) in the frontend development lifecycle, ensuring that every code change meets strict performance standards before reaching code review. It orchestrates deep audits of Lighthouse scores, Core Web Vitals (LCP, CLS, INP), and bundle size budgets, while identifying performance anti-patterns like excessive client component usage or unoptimized media. By enforcing a 'performance as a feature' philosophy, it prevents regressions and ensures a fast experience for users on all device types.
