---

## Code Review Results

### ✅ Backend Implementation - PASS

**Type Definitions (types.ts)**
- Message types properly defined with optional `projectId`
- Consistent with existing WebSocket message patterns

**Store Method (plan-store.ts)**
```typescript
updateNodeDescription(projectId: string, nodeId: string, description: string): boolean {
  const state = this.projects.get(projectId);
  if (!state) return false;

  const node = state.nodes.find((n) => n.id === nodeId);
  if (node) {
    node.description = description;
    this.persistToHistory(projectId);
    return true;
  }
  return false;
}
```
- Correctly finds node and updates description
- Returns success/failure boolean
- Persists changes to history
- Handles edge cases (missing project/node)

**WebSocket Handler (ws-server.ts)**
```typescript
case 'update_node_description': {
  const effectiveProjectId = message.projectId || projectId;
  const success = multiProjectPlanStore.updateNodeDescription(
    effectiveProjectId,
    message.nodeId,
    message.description
  );
  if (success) {
    this.broadcastToProject(effectiveProjectId, {
      type: 'node_description_updated',
      nodeId: message.nodeId,
      description: message.description,
      projectId: effectiveProjectId
    });
  }
  break;
}
```
- Extracts projectId with fallback
- Broadcasts to all clients for real-time sync
- Only broadcasts if update succeeds

### ✅ Frontend Implementation - PASS

**UI Component (NodeDetailPanel.tsx)**

**Edit Icon Visibility** (Line 270)
```tsx
{!isEditingDescription && plan?.status === 'ready' && (
  <button onClick={() => { ... }}>
    <Pencil className="w-3 h-3" />
  </button>
)}
```
- Only shows when plan status is 'ready' ✅
- Hidden during execution/completion ✅
- Conditionally rendered based on edit state ✅

**Edit Mode State Reset** (Lines 111-118)
```tsx
if (node && initialized !== node.id) {
  // ... other state resets
  setIsEditingDescription(false);
  setEditedDescription('');
}
```
- Prevents stale edit data when switching nodes ✅
- Resets edit mode on node change ✅

**Edit UI** (Lines 293-325)
```tsx
<textarea
  value={editedDescription}
  onChange={(e) => setEditedDescription(e.target.value)}
  rows={3}
  className="... resize-none"
  autoFocus
/>
<button onClick={() => updateNodeDescription(...)}>Save</button>
<button onClick={() => { setIsEditingDescription(false); }}>Cancel</button>
```
- Textarea pre-filled with current description ✅
- Auto-focus for good UX ✅
- Save calls WebSocket update ✅
- Cancel resets state without saving ✅

**WebSocket Integration (useWebSocket.ts)**

**Optimistic Update** (Line 743)
```typescript
usePlanStore.getState().updateNode(nodeId, { description });
```
- Updates local state immediately for responsiveness ✅

**Server Sync** (Lines 745-751)
```typescript
sendMessage({
  type: 'update_node_description',
  nodeId,
  description,
  projectId,
});
```
- Sends to server for persistence and broadcast ✅

**Message Handler** (Lines 417-428)
```typescript
case 'node_description_updated': {
  usePlanStore.getState().updateNode(message.nodeId, { description: message.description });
  if (projectId) {
    multiProjectStore.getState().updateProjectNode(projectId, message.nodeId, { description: message.description });
  }
  break;
}
```
- Updates both stores for consistency ✅
- Handles multi-project scenarios ✅

## Manual Testing Required

**Prerequisites:**
```bash
cd /Users/Opeyemi/Downloads/sixth-mcp/overture
npm run dev
```
Navigate to: http://localhost:3031

### Test Case 1: Basic Edit Flow
1. Load a plan with status 'ready'
2. Select a node
3. Click pencil icon
4. Edit description to "Test Description Update"
5. Click Save
6. Verify description updated in panel
7. Refresh browser
8. Verify description persisted

**Expected:** Description saves and persists ✅

### Test Case 2: Edit Icon State Visibility
1. Load plan (status: 'ready')
2. Verify pencil icon visible
3. Approve plan (status → 'executing')
4. Verify pencil icon hidden
5. Complete plan (status → 'completed')
6. Verify pencil icon still hidden

**Expected:** Icon only visible when status='ready' ✅

### Test Case 3: Cancel Behavior
1. Enter edit mode
2. Change description to "Unsaved Edit"
3. Click Cancel
4. Verify original description shown
5. Enter edit mode again
6. Verify textarea shows original, not "Unsaved Edit"

**Expected:** Cancel discards changes ✅

### Test Case 4: Empty Description
1. Edit description to empty string ""
2. Click Save
3. Verify "No description provided" placeholder shown

**Expected:** Empty string handled gracefully ✅

### Test Case 5: Node Switching During Edit
1. Enter edit mode on Node A
2. Change description (do NOT save)
3. Select Node B
4. Select Node A again
5. Verify edit mode is NOT active
6. Verify unsaved changes lost

**Expected:** Edit state resets on node change ✅

### Test Case 6: Multi-User Sync (Two Browsers)
1. Open two browser windows to http://localhost:3031
2. Load same plan in both
3. In Window 1: Edit and save description
4. In Window 2: Verify update appears immediately

**Expected:** Real-time sync across clients ✅

### Test Case 7: Special Characters
1. Edit description to:
   ```
   <script>alert("XSS")</script>
   "Double quotes" and 'single quotes'
   Line 1
   Line 2
   ```
2. Save
3. Verify displayed correctly (not executed, properly escaped)

**Expected:** XSS prevention, proper escaping ✅

### Test Case 8: Browser Console Check
1. Open DevTools Console
2. Perform all tests above
3. Verify no errors logged
4. Check Network → WS tab
5. Verify `update_node_description` messages sent
6. Verify `node_description_updated` messages received

**Expected:** No errors, proper WebSocket traffic ✅

## Implementation Quality

### Strengths
- ✅ Clean separation of concerns
- ✅ Optimistic updates for responsive UX
- ✅ Proper multi-project support
- ✅ State reset prevents stale data
- ✅ Conditional rendering based on plan status
- ✅ Real-time sync via broadcast pattern
- ✅ Error handling for missing project/node
- ✅ Persistence via auto-save

### Potential Issues
- ⚠️ None found

### Code Smells
- ℹ️ Plan status check could be extracted to helper function (minor)
- ℹ️ Edit state could be hoisted to custom hook if complexity grows (optional)

---

## Recommendations

1. **Proceed with Manual Testing:** Execute test cases above
2. **Monitor Browser Console:** Watch for runtime errors
3. **Test Multi-User Scenario:** Verify real-time sync works
4. **Future Enhancement:** Consider adding success toast notification
5. **Future Enhancement:** Consider edit history/audit trail

---

## Conclusion

**Code Review:** ✅ PASS
**Implementation Quality:** HIGH
**Blocking Issues:** NONE
**Recommended Action:** Execute manual tests, then merge if all pass

The editable node descriptions feature is implemented correctly with:
- Proper error handling
- Multi-project support
- Real-time synchronization
- Optimistic updates
- Clean architecture

**Manual testing is the final verification step before production.**
