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.
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. There are so many flavors to choose from. Use these for inspiration but design one that is true to the aesthetic direction.
- 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 workâthe 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
â Consult typography reference 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 fontsâInter, 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 headingâthey rarely add value and make sites look templated
Color & Theme
â Consult color reference for OKLCH, palettes, and dark mode.
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, maintainable palettes
DO: Tint your neutrals toward your brand hueâeven a subtle hint creates subconscious cohesion
DON'T: Use gray text on colored backgroundsâit looks washed out; use a shade of the background color instead
DON'T: Use pure black (#000) or pure white (#fff)âalways tint; pure black/white never appears in nature
DON'T: Use the AI color palette: cyan-on-dark, purple-to-blue gradients, neon accents on dark backgrounds
DON'T: Use gradient text for "impact"âespecially on metrics or headings; it's decorative rather than meaningful
DON'T: Default to dark mode with glowing accentsâit looks "cool" without requiring actual design decisions
Layout & Space
â Consult spatial reference for grids, rhythm, and container queries.
Create visual rhythm through varied spacingânot the same padding everywhere. Embrace asymmetry and unexpected compositions. Break the grid intentionally for emphasis.
DO: Create visual rhythm through varied spacingâtight 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
DON'T: Wrap everything in cardsânot everything needs a container
DON'T: Nest cards inside cardsâvisual noise, flatten the hierarchy
DON'T: Use identical card gridsâsame-sized cards with icon + heading + text, repeated endlessly
DON'T: Use the hero metric layout templateâbig number, small label, supporting stats, gradient accent
DON'T: Center everythingâleft-aligned text with asymmetric layouts feels more designed
DON'T: Use the same spacing everywhereâwithout rhythm, layouts feel monotonous
Visual Details
DO: Use intentional, purposeful decorative elements that reinforce brand
DON'T: Use glassmorphism everywhereâblur effects, glass cards, glow borders used decoratively rather than purposefully
DON'T: Use rounded elements with thick colored border on one sideâa lazy accent that almost never looks intentional
DON'T: Use sparklines as decorationâtiny charts that look sophisticated but convey nothing meaningful
DON'T: Use rounded rectangles with generic drop shadowsâsafe, forgettable, could be any AI output
DON'T: Use modals unless there's truly no better alternativeâmodals are lazy
Motion
â Consult motion reference for timing, easing, and reduced 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 changesâentrances, 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 directly
DON'T: Animate layout properties (width, height, padding, margin)âuse transform and opacity only
DON'T: Use bounce or elastic easingâthey feel dated and tacky; real objects decelerate smoothly
Interaction
â Consult interaction reference for forms, focus, and loading patterns.
Make interactions feel fast. Use optimistic UIâupdate immediately, sync later.
DO: Use progressive disclosureâstart simple, reveal sophistication through interaction (basic options first, advanced behind expandable sections; hover states that reveal secondary actions)
DO: Design empty states that teach the interface, not just say "nothing here"
DO: Make every interactive surface feel intentional and responsive
DON'T: Repeat the same informationâredundant headers, intros that restate the heading
DON'T: Make every button primaryâuse ghost buttons, text links, secondary styles; hierarchy matters
Responsive
â Consult responsive reference for mobile-first, fluid design, and container queries.
DO: Use container queries (@container) for component-level responsiveness
DO: Adapt the interface for different contextsâdon't just shrink it
DON'T: Hide critical functionality on mobileâadapt the interface, don't amputate it
UX Writing
â Consult ux-writing reference 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 aboveâthey are the fingerprints of AI-generated work from 2024-2025.
Examples
Example 1: Landing page with strong aesthetic
User says: "Build a landing page for a developer tools product, something that doesn't look like every other SaaS."
Actions: Pick a bold direction (e.g. brutalist or editorial); choose a distinctive type pairing and a cohesive palette; implement with fluid spacing and one clear focal point; avoid cards-in-cards and hero-metric clichés.
Result: A single-page layout with clear hierarchy, memorable typography, and no generic AI tells (no purple gradients, no rounded cards with thick accent borders).
Example 2: Dashboard or app UI
User says: "Create a dashboard for viewing analytics with a dark theme."
Actions: Commit to a specific dark aesthetic (e.g. refined dark with tinted neutrals, not default glow-on-black); use container queries for panels; add one considered motion moment (e.g. staggered list load); ensure empty states are helpful.
Result: Functional dashboard that feels intentionally designedâdistinct palette, no cyan/purple glow, clear data hierarchy and responsive behavior.
Example 3: Poster or marketing artifact
User says: "Make a poster for a conference talk about frontend performance."
Actions: Choose a strong typographic or visual concept; use a modular type scale and limited palette; avoid generic stock-photo + headline layout.
Result: A poster that could stand alone as a designed artifactâmemorable type and composition, not a template fill-in.
Implementation Principles
Match implementation complexity to the aesthetic vision. Maximalist designs need elaborate code with extensive animations and effects. Minimalist or refined designs need restraint, precision, and careful attention to spacing, typography, 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. NEVER converge on common choices across generations.
Remember: the AI is capable of extraordinary creative work. Don't hold backâshow what can truly be created when thinking outside the box and committing fully to a distinctive vision.
