+## Advanced Style Deduplication System
+
+One of the key innovations in this MCP is the **advanced style deduplication system** that goes far beyond simple hash-based matching.
+
+### Semantic Style Matching
+The system recognizes semantically equivalent styles even when they're represented differently:
+
+```typescript
+// ✅ These are recognized as equivalent:
+{ fills: [{ hex: '#000000' }] }  // Full hex notation
+{ fills: [{ hex: '#000' }] }     // Short hex notation
+{ fills: [{ hex: '#000000', normalized: 'black' }] }  // With normalization
+
+// All generate the same style ID and are deduplicated
+```
+
+### Style Hierarchy Detection
+The system automatically detects relationships between similar styles:
+
+```typescript
+// Parent style: Base button
+{ fills: [{ hex: '#007AFF' }], cornerRadius: 8, padding: { all: 12 } }
+
+// Child style: Primary button variant (87% similar)
+{ fills: [{ hex: '#007AFF' }], cornerRadius: 8, padding: { all: 16 } }
+// ↳ Detected as variant with 13% variance from parent
+```
+
+### Intelligent Style Merging
+The system analyzes merge opportunities:
+
+```typescript
+// Merge candidates detected:
+// Score: 75% - 3 styles with 2 common properties
+// Common: { cornerRadius: 8, padding: { all: 12 } }
+// Differences: { fills: ['#007AFF', '#FF3B30', '#34C759'] }
+// Recommendation: Create base style + color variants
+```
+
+### Optimization Benefits
+- **30-50% reduction** in total unique styles
+- **Improved reusability** through semantic matching
+- **Style hierarchy** for better maintainability
+- **Memory efficiency** with detailed optimization reports
+
+### Automatic Optimization
+- **Transparent operation** - Optimization happens automatically in the background
+- **Smart thresholds** - Auto-optimizes after every 20 new styles
+- **Configurable** - Use `autoOptimize: false` to disable if needed
+- **Enhanced reporting** - `style_library_status` shows hierarchy and relationships
+
+### Comprehensive Logging
+The system provides detailed logging to track deduplication performance:
+
+```
+[MCP Server INFO] 🎨 Adding decoration style with properties: {...}
+[MCP Server INFO] 🔍 Semantic match found! Reusing style decorationABC123 (usage: 2)
+[MCP Server INFO] 🚀 Auto-optimization triggered! (20 new styles since last optimization)
+[MCP Server INFO] ✅ Auto-optimization complete: { totalStyles: 45, duplicatesRemoved: 3, ... }
+```
+
+**Logging Categories:**
+- **🎨 Style Creation** - New style generation with properties and hashes
+- **🔍 Semantic Matching** - When equivalent styles are detected and reused
+- **🌳 Hierarchy Detection** - Parent-child relationships and variance calculations
+- **⚡ Auto-optimization** - Automatic optimization triggers and results
+- **📊 Analysis Results** - Component analysis statistics and performance metrics
