Frontend Premium Skill

This skill helps agents generate premium-quality frontend interfaces by:

1. Forcing creation of a design.md file (Google Stitch style) for consistency
2. Following 2026 UI/UX trends (glassmorphism, bento grids, micro-animations)
3. Ensuring WCAG 2.1 AA accessibility compliance
4. Providing quality verification and recommendations
5. Suggesting modern tech stack (Motion, Lucide/Phosphor icons, Tailwind, RSC)

🎯 Core Workflow

When working on frontend tasks, the skill enforces this process:

1. Generate design.md first - Document your design system (colors, typography, spacing, components)
2. Follow the design.md - All UI generation must reference and follow this file
3. Apply 2026 trends - Incorporate glassmorphism, bento layouts, subtle animations
4. Ensure accessibility - WCAG 2.1 AA, keyboard nav, focus management
5. Verify quality - Check adherence to design system and best practices

🔥 2026 Trends to Apply

Layout & Visuals

• Glassmorphism & Frosted Glass - Background-filter: blur, semi-transparent surfaces
• Bento Grid Layouts - Asymmetrical, card-based layouts inspired by Apple
• Micro-interactions - Subtle hover, focus, and animation states
• Dark Mode First - Design for dark mode as default, light as variant
• Gradients Subtils - Soft, natural gradients instead of harsh transitions
• Bold Typography - Expressive, large-scale typography for hierarchy
• Neumorphism Soft - Soft shadows and highlights for depth
• Skeleton Loaders - Content placeholders instead of spinners

Interactions

• Interactive Hover States - All interactive elements respond to hover/focus
• Motion Principles - Easing, timing, spring physics for natural feel
• Scroll-triggered Animations - Elements animate as they enter viewport
• Touch-friendly Targets - Minimum 48x48px tap targets

♿ Accessibility Requirements

Visual

• WCAG 2.1 AA minimum contrast ratios
• Text resize support (up to 200%)
• Color blindness friendly palettes
• Visible focus indicators (minimum 2px outline)

Interaction

• Full keyboard navigation
• Logical tab order
• Skip navigation links
• ARIA labels for non-text content
• Error identification and suggestions

Performance

• First Contentful Paint \x3C 1.8s
• Time to Interactive \x3C 3.5s
• Cumulative Layout Shift \x3C 0.1
• Optimized images and assets

🛠 Recommended Tech Stack

Framework & Rendering

• Next.js 15 (App Router, Server Components)
• React 19 with Concurrent Features
• RSC优先 (React Server Components for performance)

Styling

• Tailwind CSS - Utility-first, design token friendly
• Motion (framer-motion) - Production-grade animations
• CSS Variables - For design token consumption

Icons

• Lucide - Clean, consistent SVG icons (default)
• Phosphor - Multiple weights/styles including duotone
• Iconiq - Motion-powered animated icons (for premium interactions)

Development

• TypeScript - Strict mode for safety
• ESLint + Prettier - Code quality and formatting
• Vitest - Component testing
• Playwright - E2E testing

🔍 Quality Verification Checklist

When generating code, verify:

Design System Adherence

• All colors from design.md used consistently
• Typography scale followed exactly
• Spacing values match base unit multiples
• Component styles match specifications

Accessibility

• Color contrast ratios ≥ 4.5:1 (text), ≥ 3:1 (UI)
• All interactive elements keyboard accessible
• Focus visible and styled
• ARIA labels where needed
• Semantic HTML elements used

Performance

• No layout shifts during loading
• Images optimized and lazy-loaded
• CSS/JS minified
• Critical CSS inlined

Trends Applied

• Glassmorphism or frosted elements present
• Micro-interactions on hover/focus
• Responsive design (mobile-first)
• Dark mode variant considered

💡 Usage Tips

1. Always start with design.md - Generate it before any UI components
2. Reference it constantly - Ask "Does this match my design.md?" for every decision
3. Iterate on the design - Update design.md as you learn, then regenerate
4. Test accessibility early - Don't bolt it on at the end
5. Keep it subtle - 2026 trends favor refinement over flashiness

🚫 Common Pitfalls to Avoid

• ❌ Generating UI without a design system first
• ❌ Ignoring accessibility until QA
• ❌ Overusing trends (glassmorphism everywhere)
• ❌ Forgetting dark mode considerations
• ❌ Using animations that cause motion sickness
• ❌ Ignoring performance budgets
• ❌ Inconsistent spacing and typography
• ❌ Using raster icons instead of SVG
