Tools are responsible for executing code and play a simple and clear role in artificial intelligence systems. In contrast, sub-agents act as independent components within an AI agent that can manage specific decisions separately. The right choice between using tools and sub-agents can help develop intelligent agents that perform better without excessive complexity.
In fact, in designing AI agents, it is important to avoid over-engineering and to arrange components optimally and effectively. This approach reduces development costs and improves the quality of AI performance.
