Graph Engineering for Agentic AI Systems

By Ken Huang

Design the topology. Don't inherit it.

Most agent systems get their shape by accident - a prompt, then a tool, then a retry, then a second agent because the first one got long. Nobody writes the topology down.

Graph engineering is the discipline of declaring it on purpose: the nodes that should be designed, the edges that are legal, the state that travels with each run, and the gates that sit on every irreversible step.

Ken Huang writes for engineers who have to ship these systems and then operate them. Fourteen chapters cover:

Execution graphs and memory graphs - and what conflating them costs youWhat actually runs under LangGraph, AutoGen GraphFlow, and ADK's Workflow RuntimeWhen a loop is the right answer and a graph is over-engineeringKnowledge graphs as durable agent memorySecurity, identity, and governance for agent graphsTesting, evaluation, and verification that survive productionThe computer science underneath - and what stays true after the name fades

This paperback edition runs 364 pages and includes a full back-of-book index. Companion code and homework live on GitHub with links in the book.
