UI/UX Design
Systematic UI/UX design skill with design system creation guides, Figma workflow patterns, accessibility audit checklists, browser-based visual audit procedures, and design-to-code handoff templates. Produces consistent, accessible, conversion-optimized interfaces.
When to Use
- Creating or extending a design system (tokens, components, patterns)
- Designing new pages, features, or user flows
- Auditing existing UI for accessibility compliance
- Preparing design specifications for developer handoff
- Setting up Figma project structure and workflows
- Reviewing existing UI via automated browser screenshots and heuristic analysis
- Reviewing UI components against heuristics and platform guidelines
When NOT to Use
- Writing page content or copy (use
content-creation skill)
- Implementing frontend code (use the
frontend-engineer perspective)
- Conducting SEO audits (use
/seo-review workflow)
- Writing technical documentation (use
/docs workflow)
Design System Creation
Step 1: Audit Existing UI
Before creating a design system:
- Screenshot inventory: Capture all existing screens and components
- Pattern extraction: Identify recurring colors, typography, spacing, components
- Inconsistency map: Document where the same concept is implemented differently
- Priority matrix: Rank components by frequency of use × inconsistency severity
Step 2: Define Foundations
Build from the ground up:
| Foundation |
What to Define |
Token Naming |
| Color |
Brand, semantic, neutral, overlay palettes |
color-{category}-{shade} |
| Typography |
Font families, size scale, weights, line heights |
font-{property}-{size} |
| Spacing |
Base unit (4px or 8px), scale |
spacing-{size} |
| Border radius |
Scale from none to full |
radius-{size} |
| Elevation |
Shadow levels |
shadow-{level} |
| Motion |
Duration, easing curves |
motion-{property}-{variant} |
| Breakpoints |
Viewport thresholds |
breakpoint-{name} |
Step 3: Build Components
Follow Atomic Design progression:
- Atoms: Button, Input, Label, Icon, Badge, Avatar, Checkbox, Radio, Toggle
- Molecules: Input Group, Search Bar, Card, Dropdown, Tooltip, Alert, Breadcrumb
- Organisms: Header, Footer, Sidebar, Form, Data Table, Modal, Navigation
For each component, document:
- Variants: Primary, secondary, outline, ghost, destructive
- Sizes: xs, sm, md, lg, xl
- States: Default, hover, focus, active, disabled, loading, error
- Accessibility: ARIA role, keyboard behavior, screen reader announcement
- Responsive: Behavior at each breakpoint
- Do / Don't: Usage examples and anti-patterns
Step 4: Document and Maintain
- Publish component library with live examples
- Version with semantic versioning
- Changelog for every update
- Deprecation notices with migration guides
See design-system-checklist.md for the full creation checklist.

Accessibility Audit
See accessibility-checklist.md for the comprehensive WCAG 2.2 AA audit checklist.
Quick Audit (5-Minute Check)
- Tab through the page — can you reach and operate every interactive element?
- Zoom to 200% — does content reflow without horizontal scrolling?
- Check contrast — do all text elements meet 4.5:1 (normal) / 3:1 (large)?
- Screen reader test — do headings, landmarks, and alt text make sense?
- Keyboard-only — can you complete the primary task without a mouse?
Design-to-Code Handoff Template
When handing off designs to developers, provide:
## Component: [Name]
### Visual Spec
- Dimensions: [width × height or fluid]
- Spacing: [padding, margin in token values]
- Colors: [background, text, border in token values]
- Typography: [font, size, weight, line-height in token values]
- Border: [width, style, color, radius in token values]
- Shadow: [elevation token]
### Variants
- [variant-name]: [visual differences]
### States
- Default: [spec]
- Hover: [changes from default]
- Focus: [focus indicator spec]
- Active: [changes]
- Disabled: [opacity, cursor, interaction]
### Responsive Behavior
- Mobile (< 640px): [layout changes]
- Tablet (640–1024px): [layout changes]
- Desktop (> 1024px): [default layout]
### Interactions
- [trigger] → [animation: property, duration, easing]
### Accessibility
- Role: [ARIA role if not implicit]
- Keyboard: [key bindings]
- Screen reader: [announcement text]
### Code Reference
- Component: `<ComponentName variant="..." size="..." />`
- Tokens: `--token-name: value`
