What problem does it solve? Web projects often ship with hidden performance regressions, accessibility barriers, and SEO gaps that hurt user experience and search rankings. This Skill systematically reviews code against 150+ Lighthouse-based checks and produces prioritized, actionable findings instead of a raw checklist. ## Core Features & Use Cases - Four-category audit: Covers Performance (Core Web Vitals, resource optimization), Accessibility (WCAG perceivable/operable/understandable/robust), SEO (crawlability, on-page, technical), and Best Practices (security, modern standards, UX patterns). - Severity-ranked output: Findings are classified as Critical, High, Medium, or Low with file locations, impact explanations, and concrete fix recommendations. - Static HTML analyzer script: A read-only Bash script scans HTML files for missing doctype, viewport, lang attributes, alt text, and non-HTTPS URLs, emitting structured JSON results. - Use Case: Before deploying a React/Vite marketing site, run the audit to catch missing meta tags, oversized images, and contrast failures, then fix Critical and High issues before launch. ## Quick Start Ask the assistant to audit your project's HTML and frontend code for performance, accessibility, and SEO issues and return a severity-ranked report.
