This skill emphasizes bold creative commitment, breaking away from generic patterns, and building interfaces that are visually striking and memorable while remaining functional and accessible.

Core Philosophy

CRITICAL: Design Thinking Protocol

Before coding, ASK to understand context, then COMMIT BOLDLY to a distinctive direction:

Questions to Ask First

1. Purpose: What problem does this interface solve? Who uses it?
2. Tone: What aesthetic extreme fits? (see Tone Options below)
3. Constraints: Technical requirements (framework, performance, accessibility)?
4. Differentiation: What makes this UNFORGETTABLE? What's the one thing someone will remember?

Tone Options (Pick an Extreme)

Choose a clear aesthetic direction and execute with precision:

• Brutally minimal - stripped to essence, bold typography, vast whitespace
• Maximalist chaos - layered, dense, visually rich, controlled disorder
• Retro-futuristic - vintage meets sci-fi, nostalgic tech aesthetics
• Organic/natural - soft edges, earthy colors, nature-inspired textures
• Luxury/refined - elegant spacing, premium typography, subtle details
• Playful/toy-like - bright colors, rounded shapes, delightful interactions
• Editorial/magazine - strong typography hierarchy, asymmetric layouts
• Brutalist/raw - exposed structure, harsh contrasts, intentionally rough
• Art deco/geometric - bold patterns, metallic accents, symmetric elegance
• Soft/pastel - gentle gradients, muted tones, calming atmosphere
• Industrial/utilitarian - functional, no-nonsense, mechanical precision

After Getting Context

• Commit fully to the chosen direction - no half measures
• Present 2-3 alternative approaches with trade-offs
• Then implement with precision: production-grade, visually striking, memorable

Foundational Design Principles

Stand Out From Generic Patterns

NEVER Use These AI-Generated Aesthetics:

• Fonts: Inter, Roboto, Arial, system fonts as primary choice, Space Grotesk (overused by AI)
• Colors: Generic SaaS blue (#3B82F6), purple gradients on white backgrounds
• Patterns: Cookie-cutter layouts, predictable component arrangements
• Effects: Glass morphism, Apple design mimicry, liquid/blob backgrounds
• Overall: Anything that looks "Claude-generated" or machine-made

Instead, Create Atmosphere:

• Suggest photography, patterns, textures over flat solid colors
• Apply gradient meshes, noise textures, geometric patterns
• Use layered transparencies, dramatic shadows, decorative borders
• Consider custom cursors, grain overlays, contextual effects
• Think beyond typical patterns - you can step off the written path

Draw Inspiration From:

• Modern landing pages (Perplexity, Comet Browser, Dia Browser)
• Framer templates and their innovative approaches
• Leading brand design studios
• Historical design movements (Bauhaus, Otl Aicher, Braun) - but as inspiration, not imitation
• Beautiful background animations (CSS, SVG) - slow, looping, subtle

Visual Interest Strategies:

• Unique color pairs that aren't typical
• Animation effects that feel fresh
• Background patterns that add depth without distraction
• Typography combinations that create contrast
• Visual assets that tell a story

Core Design Philosophy

1. Simplicity Through Reduction

- Identify the essential purpose and eliminate distractions - Begin with complexity, then deliberately remove until reaching the simplest effective solution - Every element must justify its existence

1. Material Honesty Examples:

- Digital materials have unique properties - embrace them - Buttons communicate affordance through color, spacing, typography, AND shadows when intentional - Cards can use borders, background differentiation, OR dramatic shadows for depth - Animations follow real-world physics principles adapted to digital responsiveness - Clickable: Use distinct colors, hover state changes, cursor feedback, subtle lift effects - Containers: Use borders, background shifts, generous padding, OR shadow depth - Hierarchy: Use scale, weight, spacing, AND elevation when it serves the aesthetic

1. Functional Layering

- Create hierarchy through typography scale, color contrast, and spatial relationships - Layer information conceptually (primary → secondary → tertiary) - Use shadows and gradients INTENTIONALLY when they serve the aesthetic direction - Embrace functional depth: modals over content, dropdowns over UI - Avoid: glass morphism, Apple mimicry (but shadows/gradients are tools, not enemies)

1. Obsessive Detail

- Consider every pixel, interaction, and transition - Excellence emerges from hundreds of small, intentional decisions - Balance: Details should serve simplicity, not complexity - When detail conflicts with clarity, clarity wins

1. Coherent Design Language

- Every element should visually communicate its function - Elements should feel part of a unified system - Nothing should feel arbitrary

1. Invisibility of Technology

- The best technology disappears - Users should focus on content and goals, not on understanding the interface

What This Means in Practice

Color Usage:

• Base palette: 4-5 neutral shades (backgrounds, borders, text)
• Accent palette: 1-3 bold colors (CTAs, status, emphasis)
• Neutrals are slightly desaturated, warm or cool based on brand intent
• Accents are saturated enough to create clear contrast

Typography:

• Headlines: Emotional, attention-grabbing, UNEXPECTED (personality over pure legibility)
• Body/UI: Functional, highly legible (clarity over expression)
• 2-3 typefaces maximum, but make them CHARACTERFUL and distinctive
• Clear mathematical scale (e.g., 1.25x between sizes)
• NEVER default to Inter, Roboto, or Space Grotesk - find unique fonts

Animation:

• Purposeful: Guides attention, establishes relationships, provides feedback
• Subtle: Felt rather than seen (100-300ms for most interactions)
• Physics-informed: Natural easing, appropriate mass/momentum

Spacing:

• Generous negative space creates clarity and breathing room
• Mathematical relationships (e.g., 4px base, 8/16/24/32/48px scale)
• Consistent application creates visual rhythm

Design Decision Checklist

Before presenting any design, verify:

1. Purpose: Does every element serve a clear function?
2. Hierarchy: Is visual importance aligned with content importance?
3. Consistency: Do similar elements look and behave similarly?
4. Accessibility: Does it meet WCAG AA standards? (contrast, touch targets, keyboard nav)
5. Responsiveness: Does it work on mobile, tablet, desktop?
6. Uniqueness: Does this break from generic SaaS patterns?
7. Approval: Have I asked before implementing colors, fonts, sizes, layouts?

Design System Framework:

For understanding what's fixed (universal rules), project-specific (brand personality), and adaptable (context-dependent) in your design system, think of a design system.

Visual Design Standards

Color & Contrast

Color System Architecture:

Every interface needs two color roles:

1. Base/Neutral Palette (4-5 colors):

- Backgrounds (lightest) - Surface colors (cards, inputs) - Borders and dividers - Text (darkest) - Use slightly desaturated, warm or cool greys based on brand

1. Accent Palette (1-3 colors):

- Primary action (CTA buttons) - Status indicators (success, warning, error, info) - Focus/hover states - Use saturated colors for clear contrast against neutrals

Palette Structure Example:

Neutrals: slate-50, slate-100, slate-300, slate-700, slate-900
Accents: teal-500 (primary), amber-500 (warning), red-500 (error)

Color Application Rules:

• Backgrounds: Lightest neutral (slate-50 or white)
• Text: Darkest neutral for primary text (slate-900), mid-tone for secondary (slate-600)
• Buttons (primary): Accent color with white text
• Buttons (secondary): Neutral with border and dark text
• Status indicators: Specific accent (green=success, red=error, amber=warning, blue=info)
• Interactive states:

- Hover: Darken by 10-15% or shift hue slightly - Focus: Use ring/outline in accent color - Disabled: Reduce opacity to 40-50% and remove hover effects

Color Relationships:

Choose warm or cool intentionally based on brand:

• Warm greys (beige/brown undertones): Organic, approachable, trustworthy
• Cool greys (blue undertones): Modern, tech-forward, professional

Accent colors should have clear contrast with both:

• Light backgrounds (for buttons on white)
• Dark text (if used as backgrounds for white text)

Intentional Color Usage:

• Every color must serve a purpose (hierarchy, function, status, or action)
• Avoid decorative colors that don't communicate meaning
• Maintain consistency: same color = same meaning throughout

Accessibility:

• Ensure sufficient contrast for color-blind users
• Follow WCAG 2.1 AA: minimum 4.5:1 for normal text, 3:1 for large text
• Don't rely on color alone to convey information (add icons or labels)

Unique Color Strategy:

To stand out from generic patterns:

• NEVER use default SaaS blue (#3B82F6) or purple gradients on white
• Use unexpected neutrals: warm greys, soft off-whites, deep charcoals, rich blacks
• Pair neutrals with distinctive accents: terracotta + charcoal, sage + navy, coral + slate
• Dominant colors with SHARP accents outperform timid, evenly-distributed palettes
• Test combinations against "does this look AI-generated?" filter
• Vary between light and dark themes - no design should look the same

Create Atmosphere with Color:

• Gradient meshes for depth and visual interest
• Noise textures and grain overlays for tactile feel
• Layered transparencies for dimension
• Dramatic shadows for emphasis and drama

Typography Excellence

Typography Philosophy:

Typography is a primary design element that conveys personality and hierarchy.

Functional vs Emotional Typography:

• Headlines/Display: Prioritize emotion, personality, attention (legibility secondary)
• Body Text: Prioritize legibility, reading comfort, accessibility
• UI/Labels: Prioritize clarity, scannability, consistency

Font Selection:

• Use 2-3 typefaces maximum, but make them UNEXPECTED and characterful
• Limit to 3 weights per typeface (e.g., Regular 400, Medium 500, Bold 700)
• Prefer variable fonts for fine-tuned control and performance

NEVER Use These Fonts as Primary:

• Inter (overused by AI and generic SaaS)
• Roboto (too generic)
• Arial/Helvetica (default fallback vibes)
• Space Grotesk (AI generation favorite)
• System fonts as primary choice (only as fallback)

Font Version Usage:

• Display version: Headlines and hero text only - BE BOLD
• Text version: Paragraphs and long-form content - legibility matters
• Caption/Micro: Small UI labels (1-2 lines, non-critical info)

Find Distinctive Fonts:

• Google Fonts for web - but dig deeper than page 1
• Type foundries for unique options
• Choose fonts that serve your CHOSEN AESTHETIC DIRECTION
• Pair distinctive display font with refined body font

Typographic Scale:

Use mathematical relationships for size hierarchy:

• Ratio: Major third (1.25x) for moderate contrast, Perfect fourth (1.333x) for dramatic
• Base size: 16px (1rem) for body text
• Example scale (1.25x): xs: 0.64rem (10px) sm: 0.8rem (13px) base: 1rem (16px) lg: 1.25rem (20px) xl: 1.563rem (25px) 2xl: 1.953rem (31px) 3xl: 2.441rem (39px) 4xl: 3.052rem (49px) 5xl: 3.815rem (61px)

Typographic Hierarchy:

• Create clear visual distinction between levels
• Headlines, subheadings, body, captions should each have distinct size/weight
• Use combination of size, weight, and color for hierarchy

Spacing & Readability:

• Line height: 1.5x font size for body text (e.g., 16px text = 24px line-height)
• Line length: 45-75 characters optimal for readability (60-70 ideal)
• Paragraph spacing: 1-1.5em between paragraphs
• Letter spacing (tracking):

- Larger text (headlines): Slightly tighter (-0.02em to -0.05em) - Normal text (body): Default (0) - Small text (captions): Slightly looser (+0.01em to +0.03em) - General rule: As size increases, reduce tracking; as size decreases, increase tracking

Font Pairing Logic:

When using multiple typefaces, create contrast through:

• Category contrast: Serif + Sans-serif (classic, clear distinction)
• Weight contrast: Light + Bold (dynamic, energetic)
• Personality contrast: Geometric + Humanist (modern + warm)

Examples:

• Serif headlines + Sans body (editorial, trustworthy)
• Display headlines + System body (distinctive + efficient)
• Bold sans headlines + Light sans body (modern, clean)

UI Typography:

Specific guidance for interface elements:

• Button text: Semi-Bold (600), 14-16px, consistent casing (all-caps OR title case)
• Form labels: Regular (400), 14px, positioned above input
• Form input text: Regular (400), 16px minimum (prevents iOS zoom on focus)
• Placeholder text: Light (300) or desaturated color, same size as input
• Error messages: Regular (400), 12-14px, color-coded (red-ish)

Responsive Typography:

Scale type sizes across breakpoints:

// Example with Tailwind
<h1 className="text-3xl md:text-4xl lg:text-5xl">
  Responsive Headline
</h1>

// Or with CSS clamp (fluid)
h1 {
  font-size: clamp(2rem, 5vw, 4rem);
}

Reduce sizes on mobile (20-30% smaller than desktop) Reduce hierarchy levels on small screens (fewer distinct sizes)

Layout & Spatial Design

Compositional Balance:

• Every screen should feel balanced
• Pay attention to visual weight and negative space
• Use generous negative space to focus attention
• Add sufficient margins and paddings for professional, spacious look

Grid Discipline:

• Maintain consistent underlying grid system
• Create sense of order while allowing meaningful exceptions
• Use grid/flex wrappers with gap for spacing
• Prioritize wrappers over direct margins/padding on children

Spatial Relationships:

• Group related elements through proximity, alignment, and shared attributes
• Use size, color, and spacing to highlight important elements
• Guide user focus through visual hierarchy

Attention Guidance:

• Design interfaces that guide user attention effectively
• Avoid cluttered interfaces where elements compete
• Create clear paths through the content

Interaction Design

Motion Specification:

For detailed motion specs, see MOTION-SPEC.md (easing curves, duration tables, state-specific animations, implementation patterns).

User Experience Patterns

Core UX Principles:

1. Direct Manipulation

- Users interact directly with content, not through abstract controls - Examples: - Drag & drop to reorder items (not up/down buttons) - Inline editing (click to edit, not separate form) - Sliders for ranges (not numeric input with +/-) - Pinch/zoom gestures on mobile (not +/- buttons)

1. Immediate Feedback

- Every interaction provides instantaneous visual feedback (within 100ms) - Types of feedback: - Visual: Button pressed state, hover effects, color changes - Haptic: Vibration on mobile (submit, error, success) - Audio: Subtle sounds for critical actions (optional, user-controlled) - Loading: Skeleton screens, spinners for >300ms operations - Success: Checkmarks, green highlights, toast notifications - Error: Red highlights, inline error messages, shake animations

1. Consistent Behavior

- Similar-looking elements behave similarly - Examples: - Visual consistency: All primary buttons have same colors, sizes, hover states - Behavioral consistency: All modals close via X button, ESC key, and outside click - Interaction consistency: All drag targets have same hover state and drop feedback - Pattern consistency: All forms validate on blur and submit

1. Forgiveness

- Make errors difficult, but recovery easy - Prevention strategies: - Disable invalid actions (grey out unavailable buttons) - Validate inputs inline (before submission) - Confirm destructive actions (delete, overwrite) - Auto-save in background (drafts, progress) - Recovery strategies: - Undo/redo for all state changes - Soft deletes (trash/archive before permanent delete) - Clear error messages with actionable fixes - Preserve user input on errors (don't clear forms)

1. Progressive Disclosure

- Reveal details as needed rather than overwhelming users - Levels of disclosure: - Summary: Show essential info by default (card title, price, rating) - Details: Expand to show more info (description, specs, reviews) - Advanced: Hide complex options behind "Advanced settings" toggle - Examples: - Accordion: Start collapsed, expand on click - Search filters: Show 3-5 common filters, hide rest behind "More filters" - Settings: Basic settings visible, advanced behind "Show advanced"

Modern UX Patterns:

1. Conversational Interfaces Prioritize natural language interaction where appropriate: Four types: When to use: When NOT to use:

- Pure chat: Full conversation (AI assistants, support bots) - Command palette: Text-based shortcuts (Cmd+K, search everywhere) - Smart search: Natural language queries (search "meetings next week" vs filtering) - Form alternatives: Conversational data collection ("What's your name?" vs form fields) - Complex searches with multiple variables - Task guidance (wizards, onboarding) - Contextual help - Quick actions (command palette) - Simple forms (just use inputs) - Precise control interfaces (design tools, dashboards) - High-frequency repetitive tasks

1. Adaptive Layouts Respond to user context automatically: Examples:

- Time-based: Dark mode at night, light during day - Device-based: Simplified UI on mobile, full features on desktop - Connection-based: Reduce images/video on slow connections - Usage-based: Prioritize frequent actions, hide rarely-used features - Auto dark/light mode based on time or system preference - Simplified mobile navigation (hamburger menu) vs full desktop nav - Collapsed sidebar on small screens, expanded on large

1. Bold Visual Expression Aesthetic flexibility based on chosen direction:

- Shadows ALLOWED and encouraged when intentional (dramatic shadows, soft elevation) - Gradients ALLOWED for depth, accents, backgrounds, and atmosphere - NO glass morphism effects (this is the one banned technique) - NO Apple design mimicry (find your own voice) - Focus on typography, color, spacing, AND visual effects to create hierarchy - Create atmosphere: gradient meshes, noise textures, grain overlays, dramatic lighting

Navigation:

• Clear structure with intuitive navigation menus
• Implement breadcrumbs for deep hierarchies (more than 2 levels)
• Use standard UI patterns to reduce learning curve (hamburger menu, tab bars)
• Ensure predictable behavior (back button works, links look clickable)
• Maintain navigation context (highlight current page, preserve scroll position)

Styling Implementation

Component Library & Tools

Component Library:

• Strongly prefer shadcn components (v4, pre-installed in @/components/ui)
• Import individually: import {Button} from "@/components/ui/button";
• Use over plain HTML elements (<Button> over <button>)
• Avoid creating custom components with names that clash with shadcn

Styling Engine:

• Use Tailwind utility classes exclusively
• Adhere to theme variables in index.css via CSS custom properties
• Map variables in @theme (see tailwind.config.js)
• Use inline styles or CSS modules only when absolutely necessary

Icons:

• Use @phosphor-icons/react for buttons and inputs
• Example: import {Plus} from "@phosphor-icons/react"; <Plus />
• Use color for plain icon buttons
• Don't override default size or weight unless requested

Notifications:

• Use sonner for toasts
• Example: import {toast} from 'sonner'

Loading States:

• Always add loading states, spinners, placeholder animations
• Use skeletons until content renders

Layout Implementation

Spacing Strategy:

• Use grid/flex wrappers with gap for spacing
• Prioritize wrappers over direct margins/padding on children
• Nest wrappers as needed for complex layouts

Conditional Styling:

• Use ternary operators or clsx/classnames utilities
• Example: className={clsx('base-class', {'active-class': isActive})}

Responsive Design

Fluid Layouts:

• Use relative units (%, em, rem) instead of fixed pixels
• Implement CSS Grid and Flexbox for flexible layouts
• Design mobile-first, then scale up

Media Queries:

• Use breakpoints based on content needs, not specific devices
• Test across range of devices and orientations

Touch Targets:

• Minimum 44x44 pixels for interactive elements
• Provide adequate spacing between touch targets
• Consider hover states for desktop, focus states for touch/keyboard

Performance:

• Optimize assets for mobile networks
• Use CSS animations over JavaScript
• Implement lazy loading for images and videos

Accessibility Standards

Core Requirements:

• Follow WCAG 2.1 AA guidelines
• Ensure keyboard navigability for all interactive elements
• Minimum touch target size: 44×44px
• Use semantic HTML for screen reader compatibility
• Provide alternative text for images and non-text content

Implementation Details:

• Use descriptive variable and function names
• Event functions: prefix with "handle" (handleClick, handleKeyDown)
• Add accessibility attributes:

- tabindex="0" for custom interactive elements - aria-label for buttons without text - role attributes when semantic HTML isn't sufficient

• Ensure logical tab order
• Provide visible focus states

Design Process & Testing

Design Workflow

1. Understand Context:

- What problem are we solving? - Who are the users and when will they use this? - What are the success criteria?

1. Explore Options:

- Present 2-3 alternative approaches - Explain trade-offs of each option - Ask which direction resonates

1. Implement Iteratively:

- Start with structure and hierarchy - Add visual polish progressively - Test at each stage

1. Validate:

- Use playwright MCP to test visual changes - Check across different screen sizes - Verify accessibility

Testing Checklist

Visual Testing:

• Use playwright MCP when available for automated testing
• Check responsive behavior at common breakpoints
• Verify touch targets on mobile
• Test with different content lengths (short, long, edge cases)

Accessibility Testing:

• Test keyboard navigation
• Verify screen reader compatibility
• Check color contrast ratios
• Ensure focus states are visible

Cross-Device Testing:

• Test on actual devices, not just emulators
• Check different browsers (Chrome, Firefox, Safari)
• Verify touch interactions on mobile
• Test landscape and portrait orientations

Examples

Example 1: Designing a Button

Initial Question to Ask:

Before I implement this button, I have a few design questions:
1. What's the primary action you want to emphasize?
2. Do you have brand colors in mind, or should I suggest options?
3. What emotion should this button convey? (urgent, calm, playful, professional)

After Getting Approval, Implementation:

import { Button } from "@/components/ui/button";
import { ArrowRight } from "@phosphor-icons/react";

<Button
  className="bg-slate-800 hover:bg-slate-700 text-white px-6 py-3 rounded-lg transition-colors duration-200"
>
  Get Started
  <ArrowRight className="ml-2" />
</Button>

Example 2: Typography Hierarchy

Question First:

For this content hierarchy, I'm thinking:
- Headline: Large, bold, attention-grabbing
- Subheading: Medium, regular weight
- Body: Smaller, optimized for reading

Should we go bold and contemporary, or subtle and refined?

Implementation After Approval:

<div className="space-y-4">
  <h1 className="text-5xl font-bold tracking-tight text-slate-900">
    Headline Here
  </h1>
  <h2 className="text-2xl text-slate-600">
    Supporting subheading
  </h2>
  <p className="text-base leading-relaxed text-slate-700">
    Body text optimized for readability with proper line height.
  </p>
</div>

Example 3: Unique Color Palette Suggestion

Presenting Options:

I'd like to suggest three color directions that break from typical SaaS patterns:

1. **Warm Earth Tones**
   - Base: Warm grey (#E8E2DC)
   - Accent: Terracotta (#C86E4B)
   - For: Organic, trustworthy feel

2. **Cool Midnight**
   - Base: Deep navy (#1A2332)
   - Accent: Cyan (#4ECDC4)
   - For: Modern, tech-forward feel

3. **Soft Pastels**
   - Base: Soft pink (#FFE5E5)
   - Accent: Sage green (#9DB5A4)
   - For: Calm, approachable feel

Which direction feels right for your brand?

Common Patterns to Avoid

❌ NEVER:

• Use Inter, Roboto, Arial, Space Grotesk as primary fonts
• Use generic SaaS blue (#3B82F6) or purple gradients on white
• Copy Apple's design language or use glass morphism
• Create cookie-cutter layouts that look AI-generated
• Skip asking about context before designing
• Converge on common choices across generations (vary everything!)
• Use animations that delay user actions
• Create cluttered interfaces where elements compete

✅ ALWAYS:

• Ask about purpose, tone, constraints, differentiation FIRST
• Then commit BOLDLY to a distinctive aesthetic direction
• Use unexpected, characterful typography choices
• Create atmosphere: shadows, gradients, textures, grain (when intentional)
• Dominant colors with sharp accents (not timid, evenly-distributed palettes)
• Provide immediate feedback for interactions
• Test with real devices
• Validate accessibility (it enables creativity, not limits it)
• Remember: Claude is capable of extraordinary creative work - don't hold back!
