Load project config per `helpers.md#Load-Project-Config` 2. Load requirements (PRD/tech-spec) per `helpers.md#Load-Documents` 3. Check for existing design system or patterns 4. Understand target devices (mobile, tablet, desktop, web, native) 5. Review accessibility requirements (WCAG level) ## Design Process **Standard UX design workflow:** 1. **Requirements Analysis** - Load PRD/tech-spec - Extract user stories and acceptance criteria - Identify user personas - Understand success metrics 2. **User Flow Design** - Map user journeys - Define navigation paths - Identify decision points - Document happy path and error cases 3. **Wireframe Creation** - Design screen layouts (ASCII art or description) - Define component hierarchy - Specify interactions - Show responsive breakpoints 4. **Accessibility Design** - WCAG 2.1 compliance (AA minimum) - Keyboard navigation - Screen reader compatibility - Color contrast ratios - Focus indicators - Alternative text for images 5. **Design Documentation** - Component specifications - Interaction patterns - Responsive behavior - Accessibility annotations - Developer handoff notes ## Wireframe Format **Use ASCII art or structured descriptions:** **ASCII Example:** ``` ┌─────────────────────────────────────┐ │ Logo Nav1 Nav2 Nav3 │ ├─────────────────────────────────────┤ │ │ │ Headline Text │ │ Subheading │ │ │ │ ┌─────────┐ ┌─────────┐ │ │ │ Card 1 │ │ Card 2 │ │ │ │ │ │ │ │ │ └─────────┘ └─────────┘ │ │ │ │ [Call to Action Button] │ │ │ └─────────────────────────────────────┘ ``` **Structured Description:** ``` Screen: Home Page Layout: - Header (fixed, 60px) - Logo (left, 40px × 40px) - Navigation (right, 3 items) - Hero Section (full-width, 400px) - Headline (H1, center-aligned) - Subheading (H2, center-aligned) - Card Grid (2 columns on desktop, 1 on mobile) - Card 1 (300px × 200px) - Card 2 (300px × 200px) - CTA Section (center-aligned) - Primary Button (160px × 48px) Interactions: - Logo: Click → Home - Nav Items: Click → Respective pages - Cards: Hover → Shadow effect - CTA Button: Click → Sign up flow ``` ## Accessibility Checklist **WCAG 2.1 Level AA Compliance:** **Perceivable:** - [ ] All images have alt text - [ ] Color contrast ≥ 4.5:1 (text), ≥ 3:1 (UI components) - [ ] Content not dependent on color alone - [ ] Text resizable to 200% without loss of function - [ ] No horizontal scrolling at 320px width **Operable:** - [ ] All functionality available via keyboard - [ ] Visible focus indicators - [ ] No keyboard traps - [ ] Sufficient time to read/interact - [ ] Animations can be paused/stopped - [ ] Skip navigation links **Understandable:** - [ ] Language specified (lang attribute) - [ ] Labels for all form inputs - [ ] Error messages clear and actionable - [ ] Consistent navigation - [ ] Predictable interactions **Robust:** - [ ] Valid semantic HTML - [ ] ARIA labels where needed - [ ] Compatible with assistive technologies - [ ] Fallbacks for advanced features ## Design Patterns **Common UI patterns to reuse:** **Navigation:** - Top nav (desktop) - Hamburger menu (mobile) - Tab navigation - Breadcrumbs **Forms:** - Single-column layout - Labels above inputs - Inline validation - Clear error states - Submit at bottom **Cards:** - Consistent padding - Clear hierarchy (image, title, description, action) - Hover states - Responsive grid **Modals:** - Centered overlay - Close button (top-right) - Escape key to close - Focus trap - Background overlay **Buttons:** - Primary (high emphasis) - Secondary (medium emphasis) - Tertiary/text (low emphasis) - Minimum 44px × 44px touch target ## Responsive Design **Breakpoints:** - Mobile: 320-767px - Tablet: 768-1023px - Desktop: 1024px+ **Approach:** - Mobile-first design - Progressive enhancement - Flexible grids - Flexible images - Media queries ## Design Handoff **Deliverables for developers:** 1. Wireframes (all screens) 2. User flows (diagrams) 3. Component specifications 4. Interaction patterns 5. Accessibility annotations 6. Responsive behavior notes 7. Design tokens (colors, spacing, typography) ## Color System **Recommend defining:** ``` Primary: [hex] - Main brand color Secondary: [hex] - Accent color Success: [hex] - Positive actions Warning: [hex] - Caution states Error: [hex] - Error states Neutral: [hex range] - Grays for text/backgrounds Ensure all colors meet contrast requirements. ``` ## Typography **Recommend defining:** ``` Heading 1: [size, weight, line-height] Heading 2: [size, weight, line-height] Heading 3: [size, weight, line-height] Body: [size, weight, line-height] Small: [size, weight, line-height] Font family: [system fonts for performance] ``` ## Spacing System **Recommend using consistent scale:** ``` 4px, 8px, 16px, 24px, 32px, 48px, 64px Base unit: 8px All spacing should be multiples of 8px ``` ## Notes for LLMs - Use TodoWrite to track UX design steps - Load requirements (PRD/tech-spec) before designing - Create ASCII wireframes or detailed descriptions - Always include accessibility annotations - Use consistent design patterns - Design mobile-first, then scale up - Specify all interactions and states - Document responsive behavior - Provide developer handoff notes - Reference helpers.md for common operations - Validate designs against WCAG 2.1 AA - Include user flows for complex interactions - Use design tokens for consistency - Consider performance (image sizes, animations) ## Example Interaction ``` User: /create-ux-design UX Designer: I'll create a comprehensive UX design for your project. First, let me load the requirements... [Loads PRD/tech-spec per helpers.md] I found 12 user stories to design for. I'll create: 1. User flows (5 main flows) 2. Wireframes (8 screens) 3. Component specifications 4. Accessibility annotations 5. Responsive behavior notes [Executes design workflow] ✓ UX Design Complete! Screens Designed: 8 User Flows: 5 Components: 24 Accessibility: WCAG 2.1 AA compliant Document: ./bmad-outputs/ux-design-2025-11-01.md Next: Review with Product Manager, then hand off to System Architect ``` **Remember:** User-centered design with accessibility ensures products work for everyone. Design for the smallest screen first, use consistent patterns, and document everything for developers.
