Best Claude skills for accessibility in 2026

HTML-first hi-fi design skill: interactive prototypes, slide decks, animation demos, design variant exploration, visual direction advising, and expert critique. Triggers: make a prototype, design demo, interactive prototype, HTML presentation, animation demo, design variants, hi-fi design, UI mockup, prototype, design exploration, make an HTML page, make a visualization, app prototype, iOS prototype, mobile app mockup, export MP4, export GIF, 60fps video, design style, design direction, design philosophy, color scheme, visual style, recommend style, pick a style, make it look good, review, does this look good, review this design. Core capabilities: Junior Designer workflow (show assumptions+reasoning+placeholders first, then iterate), anti-AI-slop checklist, React+Babel best practices, Tweaks variant switching, Speaker Notes presentation, Starter Components (slide shell/variant canvas/animation engine/device frames), App prototype rules (default real images from Wikimedia/Met/Unsplash,

Comprehensive autonomous design quality audit across accessibility (WCAG 2.2), performance, theming, responsive/adaptive design, and anti-pattern detection. Produces a prioritized report with severity ratings and fix recommendations. Use when: 'audit design', 'check accessibility', 'a11y audit', 'design review', 'UI quality check', 'WCAG audit', 'design quality'.

Extract and formalize a design system from existing UI code. Scans for every hardcoded color, font size, spacing value, border radius, and shadow across the codebase, deduplicates near-identical values, generates framework-appropriate tokens (CSS custom properties, Tailwind config, Flutter ThemeData, SCSS variables), builds a component inventory with token coverage ratings, and replaces all hardcoded values with token references. Use when you need to create design tokens, consolidate inconsistent styles, audit component consistency, replace magic numbers with named values, or set up a shared design language across a project.

Add purposeful motion to interfaces using modern CSS — scroll-driven animations, view transitions, @starting-style, and GPU-accelerated transforms. Zero JS animation libraries needed. Supports web and Flutter. Use when: 'add animation', 'animate', 'add motion', 'transitions', 'scroll animation', 'page transitions', 'loading animation', 'micro-interactions'.

Audit and fix responsive design issues across all breakpoints. Scans for fixed widths that cause mobile overflow, missing media query variants, non-responsive images, undersized touch targets below 48px, unreadable typography, and horizontal scroll violations. Auto-detects framework (Flutter, Tailwind, React, Vue, Angular) and responsive system, then fixes layouts with proper flex/grid, clamp-based fluid typography, responsive image sizing, and adequate touch target spacing. Verifies every screen at mobile (375px), tablet (768px), desktop (1280px), and wide (1920px). Use when you need to fix mobile layout bugs, audit responsive breakpoints, fix overflow issues, ensure touch targets meet accessibility minimums, or verify no horizontal scroll at any viewport width.

Build distinctive, production-grade interfaces with Ralph Wiggum velocity. Ships working code — web or mobile — with modern CSS, fluid typography, purposeful motion, and zero generic AI aesthetics. Use when: 'build UI', 'design this', 'create interface', 'make it look good', 'build screen', 'implement design', 'frontend build', 'design build'.

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".

Optimize web performance for faster loading and better user experience. Use when asked to "speed up my site", "optimize performance", "reduce load time", "fix slow loading", "improve page speed", or "performance audit".

Audit and improve web accessibility following WCAG 2.2 guidelines. Use when asked to "improve accessibility", "a11y audit", "WCAG compliance", "screen reader support", "keyboard navigation", or "make accessible".

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".
