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. You MUST have confirmed design context before doing any design work.
Required context — every design task needs at minimum:
- 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?
CRITICAL: You cannot infer this context by reading the codebase. Code tells you what was built, not who it's for or what it should feel like. Only the creator can provide this context.
Gathering order:
- Check current instructions (instant): If your loaded instructions already contain a Design Context section, proceed immediately.
- Check .impeccable.md (fast): If not in instructions, read
.impeccable.md from the project root. If it exists and contains the required context, proceed.
- Ask the user (REQUIRED): If neither source has context, ask the user directly for target audience, use cases, and brand personality before doing anything else.
Design Direction
Commit to a BOLD aesthetic direction:
- 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, etc.
- Constraints: Technical requirements (framework, performance, accessibility).
- Differentiation: What makes this UNFORGETTABLE? What's the one thing someone will remember?
CRITICAL: Choose a clear conceptual direction and execute it with precision. Bold maximalism and refined minimalism both work—the key is intentionality, not intensity.
Then 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
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
NEVER: Inter, Roboto, Arial, Open Sans, system defaults
NEVER: Monospace typography as lazy shorthand for "technical/developer" vibes
NEVER: Large icons with rounded corners above every heading
Color & Theme
Commit to a cohesive palette. Dominant colors with sharp accents outperform timid, evenly-distributed palettes.
DO: Use modern CSS color functions (oklch, color-mix, light-dark) for perceptually uniform palettes
DO: Tint your neutrals toward your brand hue
NEVER: Gray text on colored backgrounds — use a shade of the background color instead
NEVER: Pure black (#000) or pure white (#fff) — always tint
NEVER (The AI Color Palette): cyan-on-dark, purple-to-blue gradients, neon accents on dark backgrounds
NEVER: Gradient text on metrics or headings
NEVER: Default to dark mode with glowing accents
Layout & Space
Create visual rhythm through varied spacing — not the same padding everywhere.
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 for emphasis
NEVER: Wrap everything in cards
NEVER: Nest cards inside cards
NEVER: Use identical card grids — same-sized cards with icon + heading + text, repeated endlessly
NEVER: Use the hero metric layout template — big number, small label, supporting stats, gradient accent
NEVER: Center everything
Visual Details
NEVER: Glassmorphism everywhere — blur effects, glass cards, glow borders used decoratively
NEVER: Rounded elements with thick colored border on one side
NEVER: Sparklines as decoration
NEVER: Rounded rectangles with generic drop shadows
NEVER: Modals unless truly no better alternative
Motion
Focus on high-impact moments: one well-orchestrated page load with staggered reveals creates more delight than scattered micro-interactions.
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
NEVER: Animate layout properties (width, height, padding, margin) — use transform and opacity only
NEVER: Bounce or elastic easing
Interaction
DO: Use progressive disclosure — start simple, reveal sophistication through interaction
DO: Design empty states that teach the interface
DO: Make every interactive surface feel intentional and responsive
NEVER: Repeat the same information
NEVER: Make every button primary
Responsive
DO: Use container queries (@container) for component-level responsiveness
DO: Adapt the interface for different contexts — don't just shrink it
NEVER: Hide critical functionality on mobile
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?"
Implementation Principles
Match implementation complexity to the aesthetic vision. Maximalist designs need elaborate code with extensive animations. Minimalist designs need restraint, precision, careful attention to spacing and 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.
Claude is capable of extraordinary creative work. Don't hold back — show what can truly be created when thinking outside the box and committing fully to a distinctive vision.
