Design Consistency

Design Consistency Skill

This skill ensures all 24 AI design patterns maintain visual and interaction consistency across your application by analyzing design system usage, identifying deviations, and applying fixes automatically.

When to Use This Skill

Claude will automatically invoke this skill when:

• You ask to "check design consistency"
• You request "analyze design system"
• You want to "fix design issues"
• You say "generate style guide"
• You mention "design audit"

What Gets Analyzed

Your design system uses Tailwind CSS v4 with custom utilities. This skill checks:

Design Analysis Workflow

Step 1: Run Design Analysis

npm run design-analyze

Output shows:

• Consistency score per component
• Issues found (with severity)
• Files requiring fixes
• Recommendations

Step 2: Review Design Report

npm run design-report

Generates comprehensive report:

📋 Design Consistency Report
├── Overall Score: 78/100
├── Critical Issues: 3
├── Warnings: 12
├── Minor Issues: 8
└── Recommendations: 15

Files Requiring Fixes
├── src/components/examples/PredictiveAnticipationExample.tsx
│   └── ⚠️ Wrong spacing (p-3 should be p-4)
│   └── ⚠️ Wrong color (text-gray-500 should be text-gray-600)
├── src/components/examples/AmbientIntelligenceExample.tsx
│   └── 🔴 Shadow inconsistency
│   └── ⚠️ Animation duration mismatch

Step 3: Review Style Guide

npm run design-style-guide

Generates documentation of your design system:

Common Design Issues & Fixes

Issue 1: Inconsistent Padding

❌ Inconsistent:

<Card className="p-2">  {/* Some cards */}
<Card className="p-4">  {/* Other cards */}
<Card className="p-6">  {/* Yet more */}

✅ Consistent:

<Card className="p-6">  {/* All cards use p-6 */}

Fix Command:

npm run design-fix  # Fix one issue at a time
# or
npm run design-fix-all  # Fix all at once

Issue 2: Color Palette Deviation

❌ Inconsistent:

<button className="bg-blue-400">  {/* Random blue */}
<button className="bg-blue-600">  {/* Primary blue */}
<button className="bg-blue-800">  {/* Dark blue */}

✅ Consistent:

<button className="bg-blue-600">  {/* Primary */}
<button className="bg-blue-600 hover:bg-blue-700">  {/* Primary + hover */}

Tailwind Color System Used:

• blue-600 → Primary color
• blue-700 → Primary hover
• blue-50 → Primary light background
• gray-600 → Secondary color
• gray-700 → Secondary hover

Issue 3: Typography Inconsistency

❌ Inconsistent:

<h1 className="text-lg font-semibold">  {/* Should be xl + bold */}
<h1 className="text-2xl font-normal">  {/* Wrong weight */}
<p className="text-base font-bold">    {/* Wrong weight */}

✅ Consistent:

<h1 className="text-2xl font-bold">        {/* Page title */}
<h2 className="text-xl font-semibold">    {/* Section title */}
<p className="text-base font-normal">     {/* Body text */}
<span className="text-sm font-medium">   {/* Labels */}

Issue 4: Spacing Inconsistency

❌ Inconsistent:

<div className="space-y-2">     {/* Tight */}
<div className="space-y-8">     {/* Loose */}
<div className="gap-3">         {/* Random */}

✅ Consistent:

<div className="space-y-6">     {/* Standard section spacing */}
<div className="flex gap-4">    {/* Component spacing */}
<div className="px-6 py-4">     {/* Card padding */}

Issue 5: Component State Inconsistency

❌ Inconsistent:

{/* Disabled state - different for each component */}
<button disabled className="opacity-50">
<button disabled className="bg-gray-400">
<button disabled className="cursor-not-allowed">

✅ Consistent:

{/* All disabled buttons use same pattern */}
<button disabled className="opacity-50 cursor-not-allowed">

Issue 6: Dark Mode Issues

❌ Incomplete:

<div className="bg-white text-black">
  {/* No dark mode support */}
</div>

✅ Complete:

<div className="bg-white dark:bg-gray-900 text-black dark:text-white">
  {/* Full dark mode support */}
</div>

Integration with Pattern Development

When working on patterns (using Pattern Development skill):

• Initial Pattern Review: Check existing pattern components against design system
• Demo Component Creation: Use design system consistently in demo
• Visual Verification: Compare pattern UI against style guide
• Before Completion: Run design analysis to ensure consistency

Automated Quality Gates

Design consistency checks run:

• ✅ Before commits (pre-commit hook)
• ✅ During tests (npm test)
• ✅ During build (npm run build)
• ✅ Before deployment to Vercel
