Developer’s guide to multi-agent patterns in ADK

Summary

This article serves as a comprehensive guide to multi-agent patterns in AI development, specifically utilizing the Google Agent Development Kit (ADK). It emphasizes the importance of decentralization and specialization in AI systems, comparing them to microservices architecture. The author outlines eight essential design patterns for building modular and reliable agent teams, including Sequential Pipeline, Coordinator/Dispatcher, and Human-in-the-loop patterns. Each pattern is accompanied by pseudocode examples, illustrating how to implement these concepts effectively in production-grade applications.

Key Learnings

• 1Decentralization in AI agents enhances reliability and reduces bottlenecks, similar to microservices architecture.
• 2The Sequential Pipeline pattern simplifies debugging by ensuring a linear flow of data between agents.
• 3The Coordinator/Dispatcher pattern allows for intelligent routing of tasks to specialized agents based on user intent.
• 4Parallel execution of tasks using the Fan-Out/Gather pattern can significantly reduce latency in agent workflows.
• 5Incorporating a Human-in-the-loop pattern ensures accountability for high-stakes decisions in AI applications.
