Building AI Agents from Scratch | Part 4
Welcome back! This is Part 4 of my ADK learning series. If you’re new here, start with Part 1 (Basics), then Part 2 (State Management), and Part 3 (Workflow Agents).

This article discusses the development of a multi-agent system using the router pattern for dynamic decision-making and intent analysis. It outlines the components and functionalities of the Router Agent that skillfully delegates tasks to specialized agents, paving the way for scalable and efficient AI applications. The piece emphasizes the importance of defining clear and explicit routing rules, handling user requests effectively, and managing complexities that arise in agent systems, culminating in a sophisticated architecture ready for real-world applications.
