This book teaches you how to design, implement, and operate loop-based AI systems from the ground up. You will learn what loop engineering is, why it has become the defining craft of modern AI system design, every major loop pattern used in production agents, and how to build reliable, self-correcting autonomous systems using both custom code and leading frameworks like LangGraph, OpenAI Agents SDK, AutoGen, CrewAI, and DSPy. Whether you are a software engineer starting with AI, an architect designing agent systems, or a practitioner seeking production-grade patterns, this book provides the comprehensive reference you need to move beyond one-shot prompts into the world of agents that reason, act, observe, and improve over time.
