## Task Types

### Architecture Review
Review existing Electron application architecture and provide improvement recommendations.

**Example Prompt:**
```
Review the architecture of our Electron app at /path/to/project.
Focus on: IPC patterns, security, and maintainability.
```

### Security Audit
Perform security assessment of Electron application configuration and code.

**Example Prompt:**
```
Audit the security of our Electron app. Check:
- Context isolation and sandbox configuration
- IPC channel security
- CSP headers
- Code signing setup
```

### Performance Analysis
Analyze and optimize Electron application performance.

**Example Prompt:**
```
Our Electron app takes 8 seconds to start. Analyze startup
performance and provide optimization recommendations.
```

### IPC Design
Design IPC communication patterns for specific features.

**Example Prompt:**
```
Design IPC architecture for a file sync feature that needs:
- Real-time progress updates
- Cancellation support
- Error handling with retry
```

### Migration Planning
Plan migration between Electron versions or frameworks.

**Example Prompt:**
```
Plan migration from Electron 22 to Electron 28. Identify:
- Breaking changes
- Deprecated APIs
- New security requirements
```

## Knowledge Base

### Electron Architecture Principles

1. **Process Separation**: Main process handles system operations; renderer handles UI
2. **Context Isolation**: Always enable to prevent prototype pollution
3. **Principle of Least Privilege**: Request only necessary permissions
4. **Defense in Depth**: Multiple security layers

### IPC Best Practices

```typescript
// Good: Typed, validated IPC
ipcMain.handle('file:read', async (event, filePath: string) => {
  if (!isPathAllowed(filePath)) throw new Error('Access denied');
  return fs.promises.readFile(filePath, 'utf-8');
});

// Bad: Unrestricted IPC
ipcMain.on('execute', (event, code) => eval(code)); // NEVER do this
```

### Security Checklist

- [ ] `contextIsolation: true`
- [ ] `nodeIntegration: false`
- [ ] `sandbox: true`
- [ ] `webSecurity: true`
- [ ] Preload uses `contextBridge`
- [ ] IPC channels are whitelisted
- [ ] CSP headers configured
- [ ] Code signing enabled
- [ ] Notarization (macOS)

### Performance Guidelines

| Metric | Target | Critical |
|--------|--------|----------|
| Cold Start | < 3s | > 8s |
| Memory (idle) | < 150MB | > 500MB |
| Bundle Size | < 100MB | > 300MB |
| IPC Latency | < 10ms | > 100ms |

We're building an Electron app for document editing. Need architecture
guidance for:
1. Real-time collaboration features
2. Offline-first with sync
3. Plugin system for extensions
4. Target: Windows, macOS, Linux
```

**Agent Response:**
```
## Architecture Recommendation

### Process Architecture
- Main Process: File system, sync engine, plugin host
- Renderer Process: UI, document editor, collaboration client
- Utility Process: Heavy computation, file processing

### IPC Design
[Detailed IPC channel design...]

### Sync Architecture
[CRDT-based sync strategy...]

### Plugin System
[Sandboxed plugin architecture...]

### Security Considerations
[Security requirements for each component...]

### Recommended Stack
- Electron 28+ (latest stable)
- React/Vue for UI
- Yjs for CRDT collaboration
- PouchDB for offline storage

### Implementation Phases
1. Core editor with file operations
2. Offline storage and sync
3. Collaboration layer
4. Plugin system
```
