### How Messages Sync

1. **From Web**:
   - User types in web chat
   - WebSocket sends to server
   - Server writes to session's stdin
   - Output captured and sent back via WebSocket
   - Displayed in real-time

2. **From CLI**:
   - User types in terminal
   - Output captured by service
   - Sent via WebSocket to connected web clients
   - Displayed in real-time in browser

3. **Session State**:
   - Shared across web and CLI
   - Both see same conversation
   - File operations sync to vault
   - Context tokens tracked

## 💡 Best Practices

### 1. Use Descriptive Session Names
When creating sessions, specify your project:
```javascript
metadata: {
    project: "DedicatedNodes",
    feature: "colo-offers-management"
}
```

### 2. Organize by Project
Create separate sessions for different projects:
- `DedicatedNodes-main`
- `DedicatedNodes-experiments`
- `Personal-website`

### 3. Regular Session Cleanup
- Old sessions are automatically cleaned up after 24 hours
- Important sessions are saved in your vault
- Use historical sessions to reference past conversations

### 4. Token Management
- Monitor token usage in the chat interface
- Start new sessions when approaching 200K limit
- Use concise prompts to save tokens

---

## 🔐 Security Notes

### Session IDs
- Session IDs are unique and random
- Treat them like passwords
- Don't share session IDs publicly
- Each session has its own context

### Authentication
- Web interface requires login
- All API calls protected
- WebSocket authenticated
- Sessions expire after 24 hours
