Best Practices

agent Design Principles

Single Responsibility: Each agent should have a clear, focused purpose
Modularity: Design agents as composable, reusable components
Fault Tolerance: Implement robust error handling and recovery
Scalability: Design for horizontal scaling from the start
Security First: Implement security controls at every layer

    batching: 'Batch similar requests for efficiency',
    async_processing: 'Use asynchronous processing for non-blocking operations',
    resource_pooling: 'Pool expensive resources like model instances',
    load_balancing: 'Distribute load across multiple agent instances'
  }
}

Cost Optimization

{
  cost_strategies: {
    right_sizing: 'Match resources to actual usage patterns',
    auto_scaling: 'Scale resources based on demand',
    spot_instances: 'Use preemptible instances for batch processing',
    reserved_capacity: 'Use committed use discounts for predictable workloads',
    monitoring: 'Continuous cost monitoring and optimization'
  }
}

Troubleshooting

Common Issues

agent Timeout: Optimize processing time or increase timeout limits
Memory Leaks: Implement proper resource cleanup
Authentication Failures: Verify service account permissions
Rate Limiting: Implement exponential backoff and retry logic
Model Errors: Add fallback models and error handling
