+# How to Verify AI Agent Hooks Work
+
+## Quick Verification Steps
+
+### 1. Build Check
+
+```bash
+# From root directory
+pnpm --filter lighthouse-extension run build
+pnpm --filter lighthouse-extension run build:tsc
+```
+
+If builds succeed, the hooks are properly integrated.
+
+### 2. Type Check
+
+```bash
+pnpm --filter lighthouse-extension run build:tsc
+```
+
+No TypeScript errors = hooks are correctly typed.
+
+### 3. Test in VSCode Extension Host
+
+#### Option A: Unit Test (Run existing extension test)
+
+```bash
+pnpm --filter lighthouse-extension run test -- extension.test.ts
+```
+
+Look for the "AI Agent Hooks" test section - it verifies:
+
+- Hooks are exposed via `getAIAgentHooks()`
+- All 4 methods are available
+- Workspace context can be retrieved
+
+#### Option B: Manual Verification in VSCode
+
+1. **Package the extension:**
+
+   ```bash
+   cd packages/vscode-extension
+   npm run package
+   ```
+
+2. **Install in VSCode:**
+   - Open VSCode
+   - Go to Extensions view
+   - Install from VSIX file
+
+3. **Open Developer Console:**
+   - Press `Cmd+Shift+P` (Mac) or `Ctrl+Shift+P` (Windows/Linux)
+   - Type "Developer: Toggle Developer Tools"
+   - Go to Console tab
+
+4. **Test the hooks:**
+
+   ```javascript
+   // Get the extension instance
+   const ext = vscode.extensions.getExtension("lighthouse-web3.lighthouse-storage-for-vscode");
+   if (ext && ext.isActive) {
+     const extension = ext.exports?.extension;
+
+     // Get AI hooks
+     const aiHooks = extension?.getAIAgentHooks();
+
+     // Test getWorkspaceContext
+     const context = await aiHooks?.getWorkspaceContext();
+     console.log("Workspace context:", context);
+
+     // Test onProgress
+     const unsubscribe = aiHooks?.onProgress((progress) => {
+       console.log("Progress update:", progress);
+     });
+
+     // Test onAICommand (workspace context command)
+     const result = await aiHooks?.onAICommand("lighthouse.workspace.context", {});
+     console.log("Command result:", result);
+
+     // Cleanup
+     unsubscribe?.();
+   }
+   ```
+
+### 4. Programmatic Test Script
+
+Create a test file `test-hooks-manual.ts`:
+
+```typescript
+import { createExtensionCore } from "@lighthouse-tooling/extension-core";
+import { AIAgentHooksImpl } from "./src/ai/ai-agent-hooks";
+
+async function testAIAgentHooks() {
+  console.log("Testing AI Agent Hooks...\n");
+
+  // Set API key
+  process.env.LIGHTHOUSE_API_KEY = "test-key";
+
+  // Create extension core
+  const extensionCore = createExtensionCore();
+  await extensionCore.initialize();
+
+  // Create AI hooks
+  const aiHooks = new AIAgentHooksImpl(extensionCore);
+
+  try {
+    // Test 1: getWorkspaceContext
+    console.log("Test 1: getWorkspaceContext()");
+    const context = await aiHooks.getWorkspaceContext();
+    console.log("✓ Workspace context retrieved:", !!context);
+    console.log("  - Project path:", context.projectPath || "N/A");
+    console.log("  - Files:", context.files?.length || 0);
+    console.log("");
+
+    // Test 2: onAICommand
+    console.log("Test 2: onAICommand()");
+    const result = await aiHooks.onAICommand("lighthouse.workspace.context", {});
+    console.log("✓ Command executed successfully:", !!result);
+    console.log("");
+
+    // Test 3: registerAIFunction
+    console.log("Test 3: registerAIFunction()");
+    let customFuncCalled = false;
+    aiHooks.registerAIFunction("test.custom", async (cmd) => {
+      customFuncCalled = true;
+      return { success: true, data: { message: "Custom function called" } };
+    });
+    const customResult = await aiHooks.onAICommand("test.custom", {});
+    console.log("✓ Custom function registered and called:", customFuncCalled);
+    console.log("");
+
+    // Test 4: onProgress
+    console.log("Test 4: onProgress()");
+    let progressReceived = false;
+    const unsubscribe = aiHooks.onProgress((progress) => {
+      progressReceived = true;
+      console.log("  Progress update received:", progress.title || "N/A");
+    });
+    console.log("✓ Progress callback registered");
+    unsubscribe();
+    console.log("✓ Unsubscribe function works");
+    console.log("");
+
+    console.log("✅ All tests passed!");
+  } catch (error) {
+    console.error("❌ Test failed:", error);
+  } finally {
+    aiHooks.dispose();
+    await extensionCore.dispose();
+  }
+}
+
+testAIAgentHooks();
+```
+
+Run with:
+
+```bash
+ts-node packages/vscode-extension/test-hooks-manual.ts
+```
+
+### 5. Check Build Output
+
+Verify hooks are in the built code:
+
+```bash
+grep -i "getAIAgentHooks\|AIAgentHooks" packages/vscode-extension/dist/extension.js
+```
+
+Should show:
+
+- `getAIAgentHooks()` method
+- `AIAgentHooksImpl` class
+- Import statements
+
+### 6. Lint Check
+
+```bash
+pnpm --filter lighthouse-extension run lint
+```
+
+Should only show warnings (not errors) - errors mean something is broken.
+
+## Expected Results
+
+✅ **All good if:**
+
+- Build succeeds without errors
+- TypeScript compilation succeeds
+- `getAIAgentHooks()` returns an object with 4 methods
+- No runtime errors when calling hook methods
+- Progress callbacks can be registered/unregistered
+
+❌ **Something wrong if:**
+
+- Build fails
+- TypeScript errors
+- Methods are undefined
+- Runtime errors when using hooks
