## 🛠️ Troubleshooting

### Common Issues

**Agent Not Starting**
```typescript
// Enable debug mode
const agent = new SvelteAgent({
  enabled: true,
  debug: true
});
```

**High Memory Usage**
```typescript
// Optimize memory usage
const agent = new SvelteAgent({
  bufferSize: 500,
  flushInterval: 5000,
  sampleRate: 0.01
});
```

**Missing Metrics**
- Check that the agent is enabled
- Verify your API key and project ID
- Ensure sampling rate allows data through
- Check network connectivity to StackSleuth API
