Overview
This guide covers 8 proven AI agent design patterns: ReAct, plan-and-execute, reflection, tool use, multi-agent, human-in-the-loop, code agent, and memory-augmented. Each pattern includes use cases, architecture diagrams, and code examples. Best for developers designing agent systems who need to choose the right architecture.
