What problem does it solve? Web projects often ship with hidden performance regressions, accessibility barriers, SEO gaps, and security misconfigurations that hurt user experience and search rankings. This Skill consolidates a Lighthouse-based review of over 150 checks into a single structured audit with prioritized, actionable fixes. ## Core Features & Use Cases - Four-Category Audit: Reviews 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: Classifies findings as Critical, High, Medium, or Low with file locations, impact explanations, and concrete fix recommendations. - Automated HTML Analysis: Includes a shell script that scans HTML files for missing doctype, charset, viewport, lang attributes, alt text, title tags, and non-HTTPS URLs, outputting results as JSON. - Use Case: Before launching a Next.js marketing site, run the audit to catch a missing viewport meta tag, oversized hero images failing LCP, and absent alt text, then receive a prioritized fix list. ## Quick Start Ask the assistant to audit your website or project directory for performance, accessibility, SEO, and best-practice issues and return a severity-ranked report.
