## Implementation Review

### ✅ Code Review Results

#### 1. Handler Implementation (`packages/mcp-server/src/tools/handlers.ts`)
- **Location:** Lines 1717-1814
- **Function:** `handleUpdateNodeDetail`
- **Parameters:**
  - `nodeId: string` (required)
  - `updates: { title?, description?, complexity?, expectedOutput?, risks? }`
  - `projectId?: string`
- **Logic Flow:**
  1. Determines effective project ID (provided or current)
  2. Gets project state
  3. Validates node exists
  4. Applies partial updates (only provided fields)
  5. Broadcasts `node_detail_updated` WebSocket message
  6. Returns success with updated node snapshot

**✅ VERIFIED:** All update fields are optional and applied conditionally
**✅ VERIFIED:** Returns proper error for invalid node ID
**✅ VERIFIED:** Broadcasts to correct project context

#### 2. Type Definitions (`packages/mcp-server/src/types.ts`)
- **Location:** Line 311
- **Message Type:** `node_detail_updated`
- **Payload:** `{ nodeId: string; updates: Partial<PlanNode>; projectId?: string }`

**✅ VERIFIED:** Type definition matches handler implementation
**✅ VERIFIED:** Supports partial updates via `Partial<PlanNode>`

#### 3. WebSocket Handler (`packages/ui/src/hooks/useWebSocket.ts`)
- **Location:** Lines 430-441 (message handler)
- **Message Type:** `node_detail_updated`
- **Actions:**
  1. Updates legacy plan store: `usePlanStore.getState().updateNode()`
  2. Updates multi-project store: `multiProjectStore.getState().updateProjectNode()`
  3. Logs update to console

**✅ VERIFIED:** Dual store update ensures UI synchronization
**✅ VERIFIED:** ProjectId properly scoped for multi-project support

#### 4. MCP Tool Registration (`packages/mcp-server/src/index.ts`)
- **Tool Name:** `update_node_detail`
- **Schema Location:** Lines 140-150 (Zod schema)
- **Tool Definition:** Lines 455-498
- **Handler Call:** Lines 752-767

**Zod Schema:**
```typescript
const UpdateNodeDetailSchema = z.object({
  node_id: z.string(),
  updates: z.object({
    title: z.string().optional(),
    description: z.string().optional(),
    complexity: z.enum(['low', 'medium', 'high']).optional(),
    expectedOutput: z.string().optional(),
    risks: z.string().optional(),
  }),
  project_id: z.string().optional(),
});
```

**✅ VERIFIED:** Schema enforces complexity enum validation
**✅ VERIFIED:** All fields properly typed
**✅ VERIFIED:** Handler properly parses and calls function

## Test Scenarios (Manual Testing Required)

### Test Case 1: Update Single Field - Title
**Objective:** Verify that updating only the title field leaves other fields unchanged

**Prerequisites:**

  "tool": "update_node_detail",
  "arguments": {
    "node_id": "plan_123:node_1",
    "updates": {
      "title": "Updated Title via MCP"
    }
  }
}
```

**Expected Results:**
- ✅ Response: `success: true`
- ✅ Node title updated to "Updated Title via MCP"
- ✅ Description unchanged
- ✅ Complexity unchanged
- ✅ ExpectedOutput unchanged
- ✅ Risks unchanged
- ✅ UI updates immediately (no refresh needed)
- ✅ NodeDetailPanel reflects new title

**Evidence Required:**
- Screenshot of node before update
- Screenshot of node after update
- MCP tool response JSON
- Browser console WebSocket message log

### Test Case 2: Update Multiple Fields
**Objective:** Verify multiple field updates in single call

**Steps:**
```bash
{
  "tool": "update_node_detail",
  "arguments": {
    "node_id": "plan_123:node_1",
    "updates": {
      "title": "Multi-field Update",

    }
  }
}
```

**Expected Results:**
- ✅ All three fields updated
- ✅ ExpectedOutput and risks remain unchanged
- ✅ Complexity badge shows "high" styling
- ✅ UI updates in real-time

---

### Test Case 3: Complexity Enum Values
**Objective:** Test all complexity values and visual rendering

b) Set complexity to "medium"
c) Set complexity to "high"

**Expected Results:**
- ✅ Each complexity value renders with correct badge color
- ✅ NodeDetailPanel shows updated complexity
- ✅ Invalid values (e.g., "extreme") rejected by schema validation

---

### Test Case 4: Invalid Node ID
**Objective:** Verify error handling for non-existent nodes

**Steps:**
```bash
{
  "tool": "update_node_detail",
  "arguments": {
    "node_id": "nonexistent:node_999",
    "updates": {
      "title": "This should fail"
    }
  }
}
```

**Expected Results:**
- ✅ Response: `success: false`
- ✅ Error message: "Node nonexistent:node_999 not found in project {projectId}"
- ✅ No UI changes
- ✅ No WebSocket broadcast

---

### Test Case 5: WebSocket Real-time Update
**Objective:** Verify updates propagate via WebSocket

**Setup:**
1. Open browser DevTools → Network → WS tab
2. Submit a plan
3. Call update_node_detail

**Expected Results:**
- ✅ WebSocket message received: `{ type: 'node_detail_updated', nodeId, updates, projectId }`
- ✅ Message payload contains only updated fields
- ✅ UI updates without page refresh
- ✅ No duplicate WebSocket messages

---

### Test Case 6: Expected Output Field
**Objective:** Test expectedOutput field update and display

**Steps:**
```bash
{
  "tool": "update_node_detail",
  "arguments": {
    "node_id": "plan_123:node_1",
    "updates": {
      "expectedOutput": "Should create 3 new files:\n- src/components/Widget.tsx\n- src/hooks/useWidget.ts\n- tests/Widget.test.tsx"
    }
  }
}
```

**Expected Results:**
- ✅ Expected output section appears in NodeDetailPanel
- ✅ Multi-line text rendered correctly
- ✅ Formatting preserved

---

  "tool": "update_node_detail",
  "arguments": {
    "node_id": "plan_123:node_1",
    "updates": {
      "risks": "⚠️ Breaking change - may affect existing API consumers\n⚠️ Requires database migration"
    }
  }
}
```

**Expected Results:**
- ✅ Risks section visible in NodeDetailPanel
- ✅ Warning icons/emojis rendered
- ✅ Multi-line formatting preserved

---

### Test Case 8: Multi-Project Context
**Objective:** Verify correct project scoping

**Setup:**
1. Submit plans in two different project contexts
2. Note projectId for each

**Test A - Explicit projectId:**
```bash
{
  "tool": "update_node_detail",
  "arguments": {
    "node_id": "plan_A:node_1",
    "updates": { "title": "Project A Update" },
    "project_id": "abc123456789"
  }
}
```

**Test B - Implicit projectId (uses current):**
```bash
{
  "tool": "update_node_detail",
  "arguments": {
    "node_id": "plan_B:node_1",
    "updates": { "title": "Current Project Update" }
  }
}
```

**Expected Results:**
- ✅ Test A updates only Project A's node
- ✅ Test B updates current project's node
- ✅ No cross-project contamination
- ✅ WebSocket messages include correct projectId

---

### Test Case 9: Empty Update Object

```bash
{
  "tool": "update_node_detail",
  "arguments": {
    "node_id": "plan_123:node_1",
    "updates": {}
  }
}
```

**Expected Results:**
- ✅ Response: `success: true` (no-op is valid)
- ✅ No fields changed
- ✅ No WebSocket broadcast (optimization)

---

### Test Case 10: Update During Execution
**Objective:** Verify updates work while plan is executing

**Setup:**
1. Submit and approve a plan
2. Let execution start (node goes to "active" status)
3. Update active node details

**Expected Results:**
- ✅ Update succeeds
- ✅ Node status remains "active"
- ✅ Updated details visible immediately
- ✅ Execution continues normally

## Known Issues & Edge Cases

### Implementation Analysis

**Potential Issue: Race Conditions**
- If multiple `update_node_detail` calls are made rapidly, updates could arrive out of order
- **Mitigation:** Server processes sequentially, but WebSocket delivery is async
- **Test:** Make 5 rapid updates to same node, verify final state is correct

**Potential Issue: Field Validation**
- Schema validates `complexity` enum, but other fields accept any string
- **Test:** Send extremely long strings (10KB+) for title/description
- **Expected:** No crashes, but UI may have rendering issues

**Potential Issue: Undefined vs Null**
- TypeScript allows undefined for optional fields
- **Test:** Send `null` instead of undefined for optional fields
- **Expected:** Schema validation may reject nulls

## Test Client Script

Create `/Users/Opeyemi/Downloads/sixth-mcp/overture/test-update-node-detail.mjs`:

```javascript
import { Client } from '@modelcontextprotocol/sdk/client/index.js';
import { StdioClientTransport } from '@modelcontextprotocol/sdk/client/stdio.js';

const client = new Client({
  name: 'update-node-detail-tester',
  version: '1.0.0',
}, {
  capabilities: {
    tools: {},
  },
});

const transport = new StdioClientTransport({
  command: 'node',
  args: ['dist/index.js'],
  cwd: '/Users/Opeyemi/Downloads/sixth-mcp/overture/packages/mcp-server',
});

await client.connect(transport);

// Test 1: Update single field
console.log('\n=== Test 1: Update Title ===');
const test1 = await client.callTool({
  name: 'update_node_detail',
  arguments: {
    node_id: 'test_update_plan:node_1',
    updates: {
      title: 'Updated via MCP Tool'
    }
  }
});
console.log(test1);

// Test 2: Update multiple fields
console.log('\n=== Test 2: Update Multiple Fields ===');
const test2 = await client.callTool({
  name: 'update_node_detail',
  arguments: {
    node_id: 'test_update_plan:node_1',
    updates: {
      description: 'Updated description with more details',
      complexity: 'high',
      expectedOutput: 'New expected output'
    }
  }
});
console.log(test2);

// Test 3: Invalid node ID
console.log('\n=== Test 3: Invalid Node ID ===');
const test3 = await client.callTool({
  name: 'update_node_detail',
  arguments: {
    node_id: 'invalid:node',
    updates: {
      title: 'Should fail'
    }
  }
});
console.log(test3);

await client.close();
```
