 ### 🛠️ How to Fix
 
+#### 💡 Code Example
+
+**❌ Before (causes lint error):**
+```typescript
+import { VetResult } from "@/app/types/vet-result";
+
+interface VetRecord {  // ← This interface is defined but never used
+  first_name: string;
+  last_name: string;
+  // ... other properties
+}
+
+export async function verify() {
+  // Implementation without using VetRecord
+}
+```
+
+**✅ After (fixed):**
+```typescript
+import { VetResult } from "@/app/types/vet-result";
+
+// Option 1: Remove the unused interface entirely
+export async function verify() {
+  // Implementation 
+}
+
+// Option 2: If you plan to use it later, prefix with underscore
+interface _VetRecord {  // ← Prefixed to indicate intentionally unused
+  first_name: string;
+  last_name: string;
+  // ... other properties
+}
+```

+### 🔄 Enhanced Duplicate Prevention
+
+This issue uses **intelligent duplicate detection** that:
+- ✅ **Prevents duplicate issues** for the same lint rule
+- ✅ **Updates existing issues** when violation counts change
+- ✅ **Automatically closes issues** when all violations are resolved
+- ✅ **Tracks progress** with detailed update comments
+
+If you see this issue updated automatically, it means new violations of this rule were detected or existing ones were fixed.
