Agents That Work

Every week, a new framework for building AI agents is announced. Every month, a startup raises millions to build the platform that will finally make agents work at scale. Yet, most implementations still fail in production. This book cuts through the hype to provide a battle-tested framework for building AI agents that actually work.

Written for developers, team leads, and tech executives, this book reveals why most agent systems fall apart and how to design ones that don't. It provides a disciplined approach to the entire lifecycle of agent development, from understanding the core architecture to deploying and scaling in production. You will learn how to choose the right frameworks, design reliable workflows, and master the art of prompt engineering for agent behavior. The book also covers essential topics like memory and context management, tool use and API integration, security and guardrails, and rigorous testing and evaluation.

Avoid the common pitfalls that cause agent projects to fail. This book provides practical guidance on production deployment, cost management, and building teams that can successfully build with agents. It covers both business process automation and personal productivity agents. Whether you are a solo developer or part of a large organization, this book equips you with the discipline needed to build agents that consistently deliver real value and justify the investment required to build them.
