+# Fix: Command 'codebuddy.vectorDb.showStats' Not Found
+
+## 🐞 **Problem**
+
+When clicking on the "CodeBuddy Vector DB" status bar item, users got the error:
+
+```
+command 'codebuddy.vectorDb.showStats' not found
+```
+
+## 🎯 **Root Cause**
+
+The vector database commands were registered in the extension code but were **not declared** in the `package.json` file's `contributes.commands` section. VS Code requires all commands to be declared in the manifest before they can be used.
+
+### **What Was Missing:**
+
+```json
+// package.json was missing these command declarations:
+{
+  "contributes": {
+    "commands": [
+      // ❌ Missing vector database commands
+    ]
+  }
+}
+```
+
+### **What Was Present:**
+
+```typescript
+// extension.ts - Commands were registered in code ✅
+const showStatsCommand = vscode.commands.registerCommand("codebuddy.vectorDb.showStats", async () => {
+  /* ... */
+});
+```
+
+## ✅ **Solution**
+
+Added all missing vector database command declarations to `package.json`:
+
+```json
+{
+  "contributes": {
+    "commands": [
+      // ... existing commands ...
+      {
+        "command": "codebuddy.vectorDb.showStats",
+        "title": "CodeBuddy: Show Vector Database Statistics"
+      },
+      {
+        "command": "codebuddy.vectorDb.forceReindex",
+        "title": "CodeBuddy: Force Full Reindex"
+      },
+      {
+        "command": "codebuddy.showIndexingStatus",
+        "title": "CodeBuddy: Show Indexing Status"
+      },
+      {
+        "command": "codebuddy.vectorDb.diagnostic",
+        "title": "CodeBuddy: Vector Database Diagnostic"
+      },
+      {
+        "command": "codebuddy.showPerformanceReport",
+        "title": "CodeBuddy: Show Performance Report"
+      },
+      {
+        "command": "codebuddy.clearVectorCache",
+        "title": "CodeBuddy: Clear Vector Cache"
+      },
+      {
+        "command": "codebuddy.reduceBatchSize",
+        "title": "CodeBuddy: Reduce Batch Size"
+      },
+      {
+        "command": "codebuddy.pauseIndexing",
+        "title": "CodeBuddy: Pause Indexing"
+      },
+      {
+        "command": "codebuddy.resumeIndexing",
+        "title": "CodeBuddy: Resume Indexing"
+      },
+      {
+        "command": "codebuddy.restartVectorWorker",
+        "title": "CodeBuddy: Restart Vector Worker"
+      },
+      {
+        "command": "codebuddy.emergencyStop",
+        "title": "CodeBuddy: Emergency Stop"
+      },
+      {
+        "command": "codebuddy.resumeFromEmergencyStop",
+        "title": "CodeBuddy: Resume From Emergency Stop"
+      },
+      {
+        "command": "codebuddy.optimizePerformance",
+        "title": "CodeBuddy: Optimize Performance"
+      }
+    ]
+  }
+}
+```
+
+## 🔧 **Technical Details**
+
+### **VS Code Command System:**
+
+1. **Declaration Required**: All commands must be declared in `package.json`
+2. **Registration Required**: Commands must be registered in extension code
+3. **Both Required**: VS Code needs both declaration AND registration to work
+
+### **Command Flow:**
+
+```
+package.json declares → VS Code recognizes → Extension registers → Command works
+     ✅ FIXED              ✅ NOW WORKS        ✅ ALREADY OK      ✅ SUCCESS
+```
+
+### **Previous State:**
+
+```
+package.json declares → VS Code recognizes → Extension registers → Command works
+     ❌ MISSING              ❌ NOT FOUND       ✅ ALREADY OK      ❌ FAILED
+```
+
+## 🎉 **Result**
+
+### **Before Fix:**
+
+- ❌ Clicking "CodeBuddy Vector DB" shows "command not found" error
+- ❌ All vector database commands inaccessible via Command Palette
+- ❌ Status bar integration broken
+- ❌ User feedback service couldn't show statistics
+
+### **After Fix:**
+
+- ✅ Clicking "CodeBuddy Vector DB" shows database statistics
+- ✅ All vector database commands available in Command Palette
+- ✅ Status bar integration working correctly
+- ✅ Proper user feedback and statistics display
+
+### **Commands Now Working:**
+
+- **codebuddy.vectorDb.showStats** - Shows vector database statistics
+- **codebuddy.vectorDb.forceReindex** - Forces full workspace reindex
+- **codebuddy.showIndexingStatus** - Shows current indexing progress
+- **codebuddy.vectorDb.diagnostic** - Runs vector database diagnostic
+- **All performance/production commands** - Cache management, batch size control, etc.
+
+## 📚 **Lesson Learned**
+
+Always ensure VS Code extension commands are declared in BOTH places:
+
+1. **package.json** (`contributes.commands`) - For VS Code to recognize them
+2. **extension.ts** (`vscode.commands.registerCommand`) - For functionality
+
+Missing either one will cause the command to fail! 🚀
