Designing Agentic AI Systems, Part 2: Modularity

Part 2 of the series delves into the significance of modularity in designing agentic systems, building on the foundational concepts of tools, action, and reasoning layers introduced earlier. By decomposing complex tasks into smaller, specialized sub-agents organized in a parent/child relationship, the architecture benefits from increased clarity, reduced complexity, and improved performance. This modular approach mirrors principles from microservices and domain-driven design, allowing each sub-agent to focus on a specific domain, such as returns or orders, thereby enhancing accuracy and minimizing errors. The separation of concerns means that changes to one sub-agent do not inadvertently affect others, facilitating easier maintenance and testing. As the parent agent orchestrates workflows, interactions become more transparent and logical, resulting in more precise and predictable decision flows. The series hints at future discussions on interaction patterns and implementation details using Python.
