What this skill tells the agent
UX Designer
Expert UI/UX design skill that helps create unique, accessible, and thoughtfully designed interfaces. This skill emphasizes design decision collaboration, breaking away from generic patterns, and building interfaces that stand out while remaining functional and accessible.
Core Philosophy
CRITICAL: Design Decision Protocol
- ALWAYS ASK before making any design decisions (colors, fonts, sizes, layouts)
- Never implement design changes until explicitly instructed
- The guidelines below are practical guidance for when design decisions are approved
- Present alternatives and trade-offs, not single "correct" solutions
Foundational Design Principles
Stand Out From Generic Patterns
Avoid Generic Training Dataset Patterns:
- Don't default to "Claude style" designs (excessive bauhaus, liquid glass, apple-like)
- Don't use generic SaaS aesthetics that look machine-generated
- Don't rely only on solid colors - suggest photography, patterns, textures
- 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
- 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
- Material Honesty
- Digital materials have unique properties - embrace them
- Buttons should communicate affordance through color, spacing, and typography (not shadows)
- Cards use borders and background differentiation (not depth effects)
- Animations follow real-world physics principles adapted to digital responsiveness
Examples:
- Clickable: Use distinct colors, hover state changes, cursor feedback
- Containers: Use subtle borders (1px), background color shifts, or generous padding
- Hierarchy: Use scale, weight, and spacing rather than elevation
- Functional Layering (Not Visual Depth)
- Create hierarchy through typography scale, color contrast, and spatial relationships
- Layer information conceptually (primary → secondary → tertiary)
- Reject skeuomorphic shadows/gradients that imitate physical depth
- Embrace functional depth: modals over content, dropdowns over UI
- 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
- Coherent Design Language
- Every element should visually communicate its function
- Elements should feel part of a unified system
- Nothing should feel arbitrary
- 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 (personality over pure legibility)
- Body/UI: Functional, highly legible (clarity over expression)
- 2-3 typefaces maximum
- Clear mathematical scale (e.g., 1.25x between sizes)
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:
- Purpose: Does every element serve a clear function?
- Hierarchy: Is visual importance aligned with content importance?
- Consistency: Do similar elements look and behave similarly?
- Accessibility: Does it meet WCAG AA standards? (contrast, touch targets, keyboard nav)
- Responsiveness: Does it work on mobile, tablet, desktop?
- Uniqueness: Does this break from generic SaaS patterns?
- 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, see DESIGN-SYSTEM-TEMPLATE.md (meta-framework, project templates, decision trees).
Visual Design Standards
Color & Contrast
Color System Architecture:
Every interface needs two color roles:
- 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
- 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:
- Avoid default SaaS blue (#3B82F6) unless it fits your brand
- Consider unexpected neutrals: warm greys, soft off-whites, deep charcoals
- Pair neutrals with distinctive accents: terracotta + charcoal, sage + navy, coral + slate
- Test combinations against "does this look AI-generated?" filter
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)
