## Testing Instructions

### Manual Testing

1. **Start Backend:**
```bash
cd ../BACKEND
dotnet run
```

2. **Start Frontend:**
```bash
flutter run -d macos  # or chrome, ios, etc.
```

3. **Navigate to Agents:**
- Click "Agents" in sidebar
- Should see empty state with "No Agents Yet"

4. **Test Empty State:**
- Verify empty state icon displays
- Verify "Create Your First Agent" button shows
- Click button → should show "coming soon" snackbar

5. **Test Navigation:**
- Click other sidebar items
- Come back to Agents
- Verify page state persists

### Integration Testing (Once Backend Has List Endpoint)

```dart
// Future test scenarios
- Load agents list
- Display agent cards
- Click agent card → show details
- Click menu → show options
- Create agent → refresh list
- Delete agent → remove from list
```

---

## API Integration Status

| Operation | Backend Ready | Frontend Ready | Status |
|-----------|---------------|----------------|--------|
| Create Agent | ✅ | ✅ | Ready to integrate |
| Get Agent | ✅ | ✅ | Ready to integrate |
| Update Agent | ✅ | ⏳ | UI pending |
| Delete Agent | ✅ | ⏳ | UI pending |
| List Agents | ⏳ | ✅ | Awaiting backend |

**Note:** Backend Phase 3 (list endpoints) will enable full agent grid display.

## Code Quality

### Type Safety ✅
- All variables explicitly typed
- No `dynamic` or `var` without types

### State Management ✅
- StatefulWidget for page state
- Proper `dispose()` for API client
- `setState()` for UI updates

### Error Handling ✅
- Result<T> pattern matching
- User-friendly error messages
- Retry functionality

### Performance ✅
- Efficient rebuild scoping
- Lazy loading ready (future)
- Smooth animations (300-600ms)
