What problem does it solve? Web projects often ship with hidden quality problems—slow Core Web Vitals, accessibility barriers, missing meta tags, and insecure configurations—that hurt rankings and user experience. This Skill systematically reviews code 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 specific code fixes. - Automated HTML Scanning: Includes a shell script that checks 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 marketing site, run the audit to catch a missing viewport meta tag, unoptimized LCP images, and absent alt text, then fix them in priority order. ## Quick Start Ask the assistant to audit your website's HTML files for performance, accessibility, SEO, and best-practice issues and return a prioritized list of fixes.
