## What it is
A collection of Agent Skills for optimizing web quality using Lighthouse, Chrome DevTools, Core Web Vitals, WCAG, and SEO guidance. It is stack-agnostic and provides measurement-first skills for auditing performance, accessibility, SEO, and best practices on any web project.

## Use cases
- audit my site for web quality
- optimize performance and speed up my site
- improve Core Web Vitals like LCP and CLS
- run a WCAG accessibility audit
- improve SEO and fix meta tags
- apply web security and code quality best practices

## When to choose
- you use AI coding agents and want them to run Lighthouse and Core Web Vitals audits
- you need measurement-first performance, accessibility, or SEO guidance across any frontend framework
- you want field (CrUX) plus lab (DevTools/Lighthouse) evidence for diagnosing web quality issues

## When to avoid
- you need a standalone CI performance testing tool rather than agent skills
- your project is not web-based
- you do not use an agent runtime that supports Agent Skills
