Design - Production

This skill guides Claude through creating production-ready design artifacts that development teams can confidently implement. Production design is about precision, completeness, and developer handoff quality.

Core Methodology

Purpose of Production Design

Production design provides everything developers need to build accurately:

• Complete specifications: Every state, spacing, interaction documented
• Design system consistency: Reusable components, tokens, patterns
• Developer-friendly formats: Specs that answer common dev questions
• Reduced ambiguity: Minimize back-and-forth during implementation

Production Design Process

1. Handoff Review: Understand approved concept, technical constraints
2. System Setup: Establish or use design system (components, tokens)
3. Detailed Design: Create high-fidelity screens with all states
4. Specification: Document spacing, behavior, interactions, edge cases
5. Asset Preparation: Export icons, images, animations at correct sizes
6. Developer Handoff: Package everything with clear documentation

Fidelity Requirements

Production designs must be:

• Pixel-accurate: Precise spacing, sizing, alignment
• State-complete: Loading, error, empty, success states
• Interaction-specified: Animations, transitions, micro-interactions
• Responsive-defined: Behavior at all breakpoints
• Accessible: WCAG guidelines met (AA minimum)

Tool Usage Patterns

Initial Setup & Handoff Review

Step 1: Gather Requirements

Questions to ask user:
1. What concept/direction was approved?
2. Does a design system exist? (Components, tokens)
3. What platforms? (iOS, Android, Web, Desktop)
4. What breakpoints/screen sizes?
5. Any technical constraints? (Framework, performance)
6. Timeline and which screens/flows to prioritize?
7. Do you have Figma API access for creating Figma files?

Use `view` to read:
- Approved concept files
- Design system documentation
- Brand guidelines
- Technical requirements from engineering

Step 2: Determine Output Format Based on user needs:

• Figma files: Use Figma API to create/update files (if API access provided)
• HTML/CSS: Static mockups with precise styling
• React prototypes: Interactive prototypes with real components
• Design specs: Markdown documentation for developers
• Animation files: Lottie JSON for complex animations

Creating Design System (If None Exists)

Define Design Tokens First:

// Create design-tokens.js
export const tokens = {
  colors: {
    primary: { 
      50: '#E3F2FD',
      500: '#2196F3',
      900: '#0D47A1'
    },
    neutral: {
      50: '#FAFAFA',
      500: '#9E9E9E',
      900: '#212121'
    },
    semantic: {
      success: '#4CAF50',
      error: '#F44336',
      warning: '#FF9800',
      info: '#2196F3'
    }
  },
  typography: {
    fontFamily: {
      sans: 'Inter, system-ui, sans-serif',
      mono: 'Monaco, monospace'
    },
    fontSize: {
      xs: '0.75rem',    // 12px
      sm: '0.875rem',   // 14px
      base: '1rem',     // 16px
      lg: '1.125rem',   // 18px
      xl: '1.25rem',    // 20px
      '2xl': '1.5rem',  // 24px
      '3xl': '1.875rem' // 30px
    },
    fontWeight: {
      normal: 400,
      medium: 500,
      semibold: 600,
      bold: 700
    },
    lineHeight: {
      tight: 1.25,
      normal: 1.5,
      relaxed: 1.75
    }
  },
  spacing: {
    0: '0',
    1: '0.25rem',  // 4px
    2: '0.5rem',   // 8px
    3: '0.75rem',  // 12px
    4: '1rem',     // 16px
    6: '1.5rem',   // 24px
    8: '2rem',     // 32px
    12: '3rem',    // 48px
    16: '4rem'     // 64px
  },
  borderRadius: {
    none: '0',
    sm: '0.125rem',    // 2px
    base: '0.25rem',   // 4px
    md: '0.375rem',    // 6px
    lg: '0.5rem',      // 8px
    xl: '0.75rem',     // 12px
    full: '9999px'
  },
  shadows: {
    sm: '0 1px 2px 0 rgba(0, 0, 0, 0.05)',
    base: '0 1px 3px 0 rgba(0, 0, 0, 0.1)',
    md: '0 4px 6px -1px rgba(0, 0, 0, 0.1)',
    lg: '0 10px 15px -3px rgba(0, 0, 0, 0.1)',
    xl: '0 20px 25px -5px rgba(0, 0, 0, 0.1)'
  }
};

Create Reusable Components:

// Button.jsx - Example component
import React from 'react';

export const Button = ({ 
  variant = 'primary',
  size = 'md', 
  children, 
  disabled = false,
  onClick 
}) => {
  const baseStyles = 'font-medium rounded-lg transition-all duration-200 focus:outline-none focus:ring-2 focus:ring-offset-2';
  
  const variants = {
    primary: 'bg-blue-600 text-white hover:bg-blue-700 focus:ring-blue-500 disabled:bg-blue-300',
    secondary: 'bg-gray-200 text-gray-900 hover:bg-gray-300 focus:ring-gray-500 disabled:bg-gray-100',
    danger: 'bg-red-600 text-white hover:bg-red-700 focus:ring-red-500 disabled:bg-red-300'
  };
  
  const sizes = {
    sm: 'px-3 py-1.5 text-sm',
    md: 'px-4 py-2 text-base',
    lg: 'px-6 py-3 text-lg'
  };
  
  return (
    <button
      className={`${baseStyles} ${variants[variant]} ${sizes[size]}`}
      disabled={disabled}
      onClick={onClick}
    >
      {children}
    </button>
  );
};

Working with Figma API

Note: Figma API integration requires user's Figma API token and file permissions.

Creating Figma Files Programmatically:

# First, install Figma API client if needed
# Then use Python or Node.js to interact with Figma API

# Example workflow:
# 1. Create new Figma file
# 2. Set up pages (e.g., "Components", "Screens", "Specs")
# 3. Create frames for each screen
# 4. Add components, text, shapes using API
# 5. Set up auto-layout, constraints
# 6. Add annotations and developer notes

Reading Existing Figma Files:

# Use Figma API to:
# 1. Fetch file structure
# 2. Extract component definitions
# 3. Read design tokens (colors, typography)
# 4. Export assets
# 5. Generate specs from Figma data

Creating High-Fidelity Prototypes

React Component Structure:

// Organize components logically
/components
  /ui          // Base components (Button, Input, Card)
  /features    // Feature-specific components
  /layouts     // Page layouts
  /icons       // Icon components

// Use design tokens consistently
import { tokens } from './design-tokens';

// Include all interactive states
const [isLoading, setIsLoading] = useState(false);
const [error, setError] = useState(null);
const [data, setData] = useState(null);

Deliverable Formats

File Organization

IMPORTANT: Organize all deliverables by batch in dated folders.

Each batch of production design work should be saved in its own folder: docs/design/production-batch-{number}-{MMDDYY}/

Examples:

• First production batch on Oct 24, 2025: docs/design/production-batch-1-102425/
• Second production batch (updates): docs/design/production-batch-2-110525/

Rationale:

• Version history: Tracks design iterations and handoff versions
• Prevents confusion: Clear which specs correspond to which build
• Organized: All production files for one batch stay together

Batch folder structure:

docs/design/production-batch-1-102425/
├── design-specification.md
├── component-implementation-guide.md
├── design-tokens.js

Common Pitfalls to Avoid

❌ Incomplete State Coverage

Problem: Only designing default state, forgetting hover/loading/error Instead: Design all states for every interactive element

❌ Imprecise Specifications

Problem: "Small gap" or "a bit darker" - developers have to guess Instead: Use exact values: "8px gap" or "#1E40AF"

❌ Inconsistent Spacing

Problem: Random spacing values (13px, 17px, 22px) Instead: Use spacing scale (4px, 8px, 12px, 16px, 24px, 32px...)

❌ Missing Responsive Behavior

Problem: Only designing for desktop, assuming mobile "works" Instead: Define behavior at each breakpoint

❌ Inaccessible Color Contrast

Problem: Light gray text on white background Instead: Test contrast ratios, minimum 4.5:1 for body text

❌ No Edge Case Consideration

Problem: Designs break with long names, empty lists, slow networks Instead: Design for edge cases explicitly

❌ Developer-Unfriendly Handoff

Problem: Unlabeled Figma layers, no specs, missing assets Instead: Organize files, name everything, provide complete specs

❌ Ignoring Technical Constraints

Problem: Designs requiring impossible performance or unsupported features Instead: Collaborate with engineering on feasibility

❌ Over-Engineering Animations

Problem: Complex animations that hurt performance or accessibility Instead: Keep animations subtle, purposeful, and performant
