Design Patterns for AI Agents
Elements of Reusable Human Organization for AI Agents
James Harmon
Paperback · Kindle · First Edition
Every AI agent architecture that works in production already has a name, an ancestor, and a few centuries of operating experience behind it. This is a catalog of thirty of them. Each pattern pairs a structure humans have used for generations, the assembly line, the chain of command, the jury, the writers’ room, the fire brigade, with the agent system that reinvented it, and tells you when to reach for it, what it costs in tokens, and the real deployments that prove it works. Written for the leaders and builders deciding how their organization’s AI should be organized, in the tradition of the classic Design Patterns that shaped a generation of software.

James Harmon
Kindle · First Edition
