**Agent Status Values**:
1. IDLE - Agent is online and ready to work
2. WORKING - Agent is actively working on an item
3. ERROR - Agent encountered an error
4. OFFLINE - Agent is offline (no heartbeat)
5. PAUSED - Agent is paused (manual)
6. MAINTENANCE - Agent is in maintenance mode

**Status Transitions**:
```
IDLE
  ├─ claimWork() → WORKING
  ├─ pause() → PAUSED
  ├─ maintenance() → MAINTENANCE
  └─ disconnect() → OFFLINE

WORKING
  ├─ updateProgress() → WORKING
  ├─ completeWork() → IDLE
  ├─ error() → ERROR
  ├─ pause() → PAUSED
  └─ disconnect() → OFFLINE

ERROR
  ├─ retry() → WORKING
  ├─ reset() → IDLE
  ├─ pause() → PAUSED
  └─ disconnect() → OFFLINE

PAUSED
  ├─ resume() → IDLE (or WORKING if was working)
  └─ disconnect() → OFFLINE

MAINTENANCE
  ├─ complete() → IDLE
  └─ disconnect() → OFFLINE

OFFLINE
  └─ reconnect() → IDLE (or WORKING if was working)
```

**API Endpoint**: `GET /api/agents/:id/status`

**Response**:
```json
{
  "id": "uuid",
  "name": "string",
  "status": "IDLE|WORKING|ERROR|OFFLINE|PAUSED|MAINTENANCE",
  "lastSeen": "ISO8601",
  "currentItemId": "uuid",
  "currentItemTitle": "string",
  "error": {
    "message": "string",
    "stackTrace": "string",
    "timestamp": "ISO8601"
  },
  "metrics": {
    "itemsCompleted": "number",
    "itemsFailed": "number",
    "averageTime": "number",
    "uptime": "number"
  },
  "health": {
    "status": "HEALTHY|WARNING|CRITICAL",
    "issues": ["string"]
  },
  "statusHistory": [
    {
      "status": "string",
      "timestamp": "ISO8601",
      "reason": "string"
    }
  ]
}
```

**GraphQL Query**:
```graphql
query GetAgentStatus($id: UUID!) {
  agent(id: $id) {
    id
    name
    status
    lastSeen
    currentItem {
      id
      title
    }
    error {
      message
      stackTrace
      timestamp
    }
    metrics {
      itemsCompleted
      itemsFailed
      averageTime
      uptime
    }
    health {
      status
      issues
    }
    statusHistory {
      status
      timestamp
      reason
    }
  }
}
```

**WebSocket Event**:
```javascript
// Subscribe to agent status changes
socket.on('agent:status-changed', (data) => {
  console.log(`Agent ${data.agentId} status changed to ${data.status}`);
  // Update UI
});

// Broadcast event
{
  type: 'agent:status-changed',
  agentId: 'uuid',
  status: 'WORKING',
  currentItemId: 'uuid',
  timestamp: 'ISO8601'
}
```

**Real-Time Updates**:
- Subscribe to agent status changes
- Broadcast status changes to all connected clients
- Animate status transitions
- Show status history

**Monitoring & Alerting**:
- Alert: Agent offline (5 minute timeout)
- Alert: Agent error (immediate)
- Alert: Agent health critical (based on metrics)
- Alert: Agent quota exceeded (100 agents per org)

**Performance Requirements**:
- Status update: <50ms
- Real-time broadcast: <100ms
- Status history query: <200ms
- Metrics calculation: <500ms
