SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve? Web projects often ship with hidden quality problems across performance, accessibility, SEO, and security that hurt user experience and search rankings. This Skill consolidates a full Lighthouse-style review into a single audit so you catch critical issues before launch. ## Core Features & Use Cases - Four-Area Audit: Reviews Performance (Core Web Vitals, resource optimization), Accessibility (WCAG criteria), SEO (crawlability, on-page, technical), and Best Practices (security, modern standards) across 150+ checks. - Severity-Ranked Findings: Categorizes issues as Critical, High, Medium, or Low with file locations, impact explanations, and concrete fix recommendations. - Automated HTML Scanning: Includes a shell script that checks HTML files for missing doctype, charset, viewport, lang attributes, alt text, and non-HTTPS URLs, outputting results as JSON. - Use Case: Before deploying a marketing site, run the audit to discover that your LCP exceeds 2.5s, several images lack alt text, and meta descriptions are missing, then receive a prioritized fix list. ## Quick Start Ask the agent to audit my website's HTML files for performance, accessibility, SEO, and best practices issues and give me a prioritized report.

Frequently Asked Questions about web-quality-audit

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I audit my website for performance and accessibility issues?▼

Run a web quality audit that checks Core Web Vitals (LCP, INP, CLS), WCAG accessibility criteria, SEO fundamentals, and security best practices in one pass. Findings are grouped by severity with specific code-level fix recommendations.

What does a Lighthouse-style web quality audit check?▼

It covers four areas: Performance (image compression, JavaScript size, caching, loading strategy), Accessibility (alt text, contrast, keyboard support, ARIA), SEO (titles, meta descriptions, sitemaps, structured data), and Best Practices (HTTPS, CSP headers, deprecated APIs).

When should I use a full audit instead of a focused accessibility or SEO check?▼

Use the full audit when reviewing overall site quality across multiple areas at once, such as before a launch. For single-area deep dives, use focused checks like core-web-vitals, accessibility, or SEO individually instead.

What HTML issues does the audit script detect automatically?▼

The script detects missing HTML5 doctype, missing UTF-8 charset, absent viewport meta tag, missing lang attribute, images without alt text, missing title tags, and non-HTTPS URLs. Results are output as JSON with issue and warning counts.

How are audit findings prioritized?▼

Findings are ranked into four severity levels: Critical (security vulnerabilities, complete failures), High (Core Web Vitals failures, major accessibility barriers), Medium (performance and SEO improvements), and Low (minor optimizations), each with a recommended action timeline.
