Frontend Design Skill

Create distinctive, memorable user interfaces that avoid generic AI aesthetics.

Pre-Implementation Planning

Before writing code, establish:

1. Purpose & Audience - What problem does this solve? Who uses it?
2. Tone - Choose a deliberate aesthetic direction:
   • Brutalist, maximalist, retro-futuristic, luxury, playful, editorial, organic, industrial
3. Constraints - Framework requirements, performance budgets, accessibility needs
4. Memorable Element - What's the ONE thing users will remember?

Design Principles

Typography

• Avoid: Inter, Roboto, Arial, system-ui (generic AI look)
• Prefer: Distinctive typefaces with character
• Pair display fonts with refined body options
• Size hierarchy should be dramatic, not subtle

Color & Theme

• Use CSS variables for cohesive theming
• Dominant colors with sharp accents > evenly-distributed palettes
• Commit fully to color choices - timid palettes look generic
• Dark mode should be designed, not just inverted

Motion & Animation

• Prioritize high-impact moments (page load, key interactions)
• One well-orchestrated entrance > scattered micro-interactions
• Staggered reveals create rhythm and hierarchy
• Quality over quantity

Spatial Composition

• Employ asymmetry, overlap, diagonal flow
• Break grids intentionally for emphasis
• Generous negative space OR controlled density (pick one)
• Avoid centered-everything layouts

Visual Details

• Gradient meshes, noise textures, geometric patterns
• Layered transparencies, dramatic shadows
• Custom cursors, grain overlays, decorative borders
• Details should reinforce the chosen aesthetic

Anti-Patterns

• Generic fonts (Inter, Roboto, Arial on white backgrounds)
• Purple/blue gradients on white (classic AI startup look)
• Predictable card grids with rounded corners
• Cookie-cutter component libraries without customization
• Designs that could belong to any product

Implementation Approach

1. Establish design tokens (colors, typography, spacing)
2. Build distinctive hero/header first (sets the tone)
3. Let the hero aesthetic inform component design
4. Add motion and micro-interactions last
5. Review: "Would I remember this UI tomorrow?"

Framework Notes

This skill is framework-agnostic. Apply these principles whether using:

• React/Next.js with Tailwind
• Vue/Nuxt with CSS
• Svelte with styled-components
• Plain HTML/CSS

The goal is distinctive design, not specific implementation.
