Web quality audit

Comprehensive quality review based on Google Lighthouse audits. Covers Performance, Accessibility, SEO, and Best Practices across 150+ checks.

How it works

Analyze the provided code/project for quality issues
Categorize findings by severity (Critical, High, Medium, Low)
Provide specific, actionable recommendations
Include code examples for fixes

Audit categories

Performance (40% of typical issues)

Core Web Vitals — Must pass for good page experience:

LCP (Largest Contentful Paint) < 2.5s. The largest visible element must render quickly. Optimize images, fonts, and server response time.
INP (Interaction to Next Paint) < 200ms. User interactions must feel instant. Reduce JavaScript execution time and break up long tasks.
CLS (Cumulative Layout Shift) < 0.1. Content must not jump around. Set explicit dimensions on images, embeds, and ads.

Resource Optimization:

Compress images. Use WebP/AVIF with fallbacks. Serve correctly sized images via srcset.
Minimize JavaScript. Remove unused code. Use code splitting. Defer non-critical scripts.
Optimize CSS. Extract critical CSS. Remove unused styles. Avoid @import.
Efficient fonts. Use font-display: swap. Preload critical fonts. Subset to needed characters.

Loading Strategy:

Preconnect to origins. Add <link rel="preconnect"> for third-party domains.
Preload critical assets. LCP images, fonts, and above-fold CSS.
Lazy load below-fold content. Images, iframes, and heavy components.
Cache effectively. Long cache TTLs for static assets. Immutable caching for hashed files.

Accessibility (30% of typical issues)

Perceivable:

Text alternatives. Every <img> has meaningful alt text. Decorative images use alt="".
Color contrast. Minimum 4.5:1 for normal text, 3:1 for large text (WCAG AA).
Don't rely on color alone. Use icons, patterns, or text alongside color indicators.
Captions and transcripts. Video has captions. Audio has transcripts.

Operable:

Keyboard accessible. All functionality available via keyboard. No keyboard traps.
Focus visible. Clear focus indicators on all interactive elements.
Skip links. Provide "Skip to main content" for keyboard users.
Sufficient time. Users can extend time limits. No auto-advancing content without controls.

Understandable:

Page language. Set lang attribute on <html>.
Consistent navigation. Same navigation structure across pages.
Error identification. Form errors clearly described and associated with fields.
Labels and instructions. All form inputs have associated labels.

Robust:

Valid HTML. No duplicate IDs. Properly nested elements.
ARIA used correctly. Prefer native elements. ARIA roles match behavior.
Name, role, value. Interactive elements have accessible names and correct roles.

SEO (15% of typical issues)

Crawlability:

Valid robots.txt. Doesn't block important resources.
XML sitemap. Lists all important pages. Submitted to Search Console.
Canonical URLs. Prevent duplicate content issues.
No noindex on important pages. Check meta robots and headers.

On-Page SEO:

Unique title tags. 50-60 characters. Primary keyword included.
Meta descriptions. 150-160 characters. Compelling and unique.
Heading hierarchy. Single <h1>. Logical heading structure.
Descriptive link text. Not "click here" or "read more".

Technical SEO:

Mobile-friendly. Responsive design. Tap targets ≥ 48px.
HTTPS. Secure connection required.
Fast loading. Performance directly impacts ranking.
Structured data. JSON-LD for rich snippets (Article, Product, FAQ, etc.).

Best practices (15% of typical issues)

Security:

HTTPS everywhere. No mixed content. HSTS enabled.
No vulnerable libraries. Keep dependencies updated.
CSP headers. Content Security Policy to prevent XSS.
No exposed source maps. In production builds.

Modern Standards:

No deprecated APIs. Replace document.write, synchronous XHR, etc.
Valid doctype. Use <!DOCTYPE html>.
Charset declared. <meta charset="UTF-8"> as first element in <head>.
No browser errors. Clean console. No CORS issues.

UX Patterns:

No intrusive interstitials. Especially on mobile.
Clear permission requests. Only ask when needed, with context.
No misleading buttons. Buttons do what they say.

Severity levels

Level	Description	Action
Critical	Security vulnerabilities, complete failures	Fix immediately
High	Core Web Vitals failures, major a11y barriers	Fix before launch
Medium	Performance opportunities, SEO improvements	Fix within sprint
Low	Minor optimizations, code quality	Fix when convenient

Audit output format

When performing an audit, structure findings as:

## Audit results

### Critical issues (X found)

- **[Category]** Issue description. File: `path/to/file.js:123`
  - **Impact:** Why this matters
  - **Fix:** Specific code change or recommendation

### High priority (X found)

...

### Summary

- Performance: X issues (Y critical)
- Accessibility: X issues (Y critical)
- SEO: X issues
- Best Practices: X issues

### Recommended priority

1. First fix this because...
2. Then address...
3. Finally optimize...

accessibility

schalkneethling/masonry-gridlanes-wc

Audit and improve web accessibility following WCAG 2.1 guidelines. Use when asked to "improve accessibility", "a11y audit", "WCAG compliance", "screen reader support", "keyboard navigation", or "make accessible".

best-practices

schalkneethling/masonry-gridlanes-wc

Apply modern web development best practices for security, compatibility, and code quality. Use when asked to "apply best practices", "security audit", "modernize code", "code quality review", or "check for vulnerabilities".

core-web-vitals

schalkneethling/masonry-gridlanes-wc

Optimize Core Web Vitals (LCP, INP, CLS) for better page experience and search ranking. Use when asked to "improve Core Web Vitals", "fix LCP", "reduce CLS", "optimize INP", "page experience optimization", or "fix layout shifts".

css-shared-first

schalkneethling/masonry-gridlanes-wc

Apply the Shared First CSS methodology when writing responsive styles. Use this skill whenever writing or reviewing CSS that involves media queries, responsive layouts, viewport-specific overrides, or breakpoint-driven design. Trigger when the user asks to write responsive CSS, refactor mobile-first CSS, or when any component or layout has viewport-specific styles. This skill replaces mobile-first pattern guidance — always prefer Shared First unless the user explicitly requests mobile-first.

css-token-use-validator

schalkneethling/masonry-gridlanes-wc

Validate CSS custom property usage against token definitions. Use when the user wants to check if CSS variables are properly defined, find unused tokens, detect typos in var() references, audit custom property, or when working between Figma design files and code. Works with single files, directories, or entire projects. Can be used as a Claude Code hook to automatically validate after CSS edits.

fixing-accessibility

schalkneethling/masonry-gridlanes-wc

Audit and fix HTML accessibility issues including ARIA labels, keyboard navigation, focus management, color contrast, and form errors. Use when adding interactive controls, forms, dialogs, or reviewing WCAG compliance.
