Web Quality Skills

About

An unofficial, measurement-first collection of agent skills for optimizing web projects using Google Lighthouse, Chrome DevTools for agents, Core Web Vitals, WCAG, and search guidance. Where interface guidelines say what to build, these skills focus on building it performantly and accessibly: live Lighthouse audits, performance traces and insights for diagnosing LCP, INP, CLS, network, and main-thread bottlenecks, and combined field plus lab measurement. It is stack-agnostic across React, Vue, Angular, Svelte, Next.js, Nuxt, Astro, and plain HTML.
