Frontend Design

Frontend Design

This skill guides creation of distinctive, production-grade frontend interfaces that avoid generic "AI slop" aesthetics. Implement real working code with exceptional attention to aesthetic details and creative choices.

Context Gathering Protocol

Design skills produce generic output without project context. Before doing any design work, confirm:

• Target audience: Who uses this product and in what context?
• Use cases: What jobs are they trying to get done?
• Brand personality/tone: How should the interface feel?

Gathering order:

1. Check current instructions: If your loaded instructions contain a Design Context section, proceed immediately.
2. Check .impeccable.md: If it exists in the project root and has context, use it.
3. Ask the user: If neither source has context, ask these 3 questions before proceeding.

Design Direction

Commit to a BOLD aesthetic direction before writing any code:

• Purpose: What problem does this interface solve? Who uses it?
• Tone: Pick an extreme — brutally minimal, maximalist chaos, retro-futuristic, organic/natural, luxury/refined, playful/toy-like, editorial/magazine, brutalist/raw, art deco/geometric, soft/pastel, industrial/utilitarian
• Differentiation: What makes this UNFORGETTABLE? What's the one thing users remember?

CRITICAL: Choose a clear conceptual direction and execute with precision. Bold maximalism and refined minimalism both work — the key is intentionality, not intensity.

Implement working code that is:

• Production-grade and functional
• Visually striking and memorable
• Cohesive with a clear aesthetic point-of-view
• Meticulously refined in every detail

Frontend Aesthetics Guidelines

Typography

→ See [typography reference](reference/typography.md) for scales, pairing, and loading strategies.

Choose fonts that are beautiful, unique, and interesting. Pair a distinctive display font with a refined body font.

DO: Use a modular type scale with fluid sizing (clamp()) DO: Vary font weights and sizes to create clear visual hierarchy DON'T: Use overused fonts — Inter, Roboto, Arial, Open Sans, system defaults DON'T: Use monospace typography as lazy shorthand for "technical/developer" vibes DON'T: Put large icons with rounded corners above every heading

Color & Theme

→ See [color reference](reference/color-and-contrast.md) for OKLCH, palettes, and dark mode.

DO: Use modern CSS color functions (oklch, color-mix, light-dark()) for perceptually uniform palettes DO: Tint your neutrals toward your brand hue DON'T: Use gray text on colored backgrounds — looks washed out; use a shade of the bg color instead DON'T: Use pure black (#000) or pure white (#fff) — always tint DON'T: Use the AI color palette: cyan-on-dark, purple-to-blue gradients, neon on dark DON'T: Use gradient text for "impact" on metrics or headings DON'T: Default to dark mode with glowing accents without real design decisions

Layout & Space

→ See [spatial reference](reference/spatial-design.md) for grids, rhythm, and container queries.

DO: Create visual rhythm through varied spacing — tight groupings, generous separations DO: Use fluid spacing with clamp() that breathes on larger screens DO: Use asymmetry and unexpected compositions; break the grid intentionally DON'T: Wrap everything in cards — not everything needs a container DON'T: Nest cards inside cards — visual noise DON'T: Use identical card grids (same-sized card with icon + heading + text, repeated) DON'T: Center everything — left-aligned text with asymmetric layouts feels more designed DON'T: Use the same spacing everywhere

Visual Details

DO: Use intentional, purposeful decorative elements that reinforce brand DON'T: Use glassmorphism everywhere — blur/glass/glow as decoration rather than purpose DON'T: Use rounded rectangles with generic drop shadows — forgettable DON'T: Use sparklines as decoration DON'T: Use modals unless there's truly no better alternative

Motion

→ See [motion reference](reference/motion-design.md) for timing, easing, and reduced motion.

DO: Use motion to convey state changes — entrances, exits, feedback DO: Use exponential easing (ease-out-quart/quint/expo) for natural deceleration DO: For height animations, use grid-template-rows transitions instead of animating height DON'T: Animate layout properties (width, height, padding, margin) — use transform and opacity only DON'T: Use bounce or elastic easing — dated and tacky

Interaction

→ See [interaction reference](reference/interaction-design.md) for forms, focus, loading patterns.

DO: Use progressive disclosure — start simple, reveal sophistication through interaction DO: Design empty states that teach the interface, not just say "nothing here" DON'T: Make every button primary — use ghost buttons, text links, secondary styles DON'T: Repeat the same information redundantly

Responsive

→ See [responsive reference](reference/responsive-design.md) for mobile-first, fluid design.

DO: Use container queries (@container) for component-level responsiveness DO: Adapt the interface for different contexts — don't just shrink it DON'T: Hide critical functionality on mobile

UX Writing

→ See [UX writing reference](reference/ux-writing.md) for labels, errors, and empty states.

DO: Make every word earn its place DON'T: Repeat information users can already see

The AI Slop Test

Critical quality check: If you showed this interface to someone and said "AI made this," would they believe you immediately? If yes, that's the problem.

A distinctive interface should make someone ask "how was this made?" not "which AI made this?"

Review the DON'T guidelines above — they are the fingerprints of AI-generated work from 2024-2025.

Implementation Principles

Match implementation complexity to the aesthetic vision:

• Maximalist designs → elaborate code, extensive animations, rich effects
• Minimalist designs → restraint, precision, careful spacing, subtle details

Interpret creatively and make unexpected choices that feel genuinely designed for the context. No design should be the same. Vary between light and dark themes, different fonts, different aesthetics. NEVER converge on common choices across generations.

Quick Reference: What to Avoid

| Category | DON'T | |----------|-------| | Fonts | Inter, Roboto, Arial, Open Sans | | Colors | Pure black/white, purple gradients, gray on color | | Layout | Cards in cards, centered everything, identical grids | | Motion | Bounce/elastic easing, animating height/width | | Visual | Glassmorphism everywhere, gradient text, generic shadows | | Writing | "OK", "Submit", redundant copy, vague errors |
