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 systematically reviews code and HTML against 150+ Lighthouse-based checks and produces prioritized, actionable findings. ## 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). - 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 read-only shell script that scans HTML files for missing doctype, viewport, lang attributes, alt text, and non-HTTPS URLs, outputting structured JSON. - Use Case: Before a product launch, run the audit against your site's HTML output to catch missing alt attributes, mixed-content HTTP links, and absent meta tags, then fix Critical and High issues before deploy. ## Quick Start Audit the HTML files in my project's dist folder for quality issues and give me a prioritized list of fixes.
