Stop running one agent at a time.

You open Claude Code. One agent. One task. You wait, you read, you tell it what to do next. Again.

Meanwhile Anthropic's own engineers are running hundreds of agents through eight phase gates to produce a million lines of code in under two weeks, with the full test suite green before merge. Developers on Reddit are shipping fully orchestrated pull requests with 70 agents in a three hour build. The difference isn't talent. It's a graph.

This book hands you the complete agent graph system, built on the subagents and dynamic workflows Claude Code already ships. You'll run your first three node graph in ten minutes and watch two agents start inside the same second. By chapter 4 they fan out across your own repository and merge one verified answer. By chapter 6 they check each other, and you'll watch a verifier reject exactly what a self grading agent waved straight through. By day 30 you'll have 12 working systems, a graph running on your own recurring work, and one of them scoped, priced and ready to hand a client for $3,000.

Every graph in this book comes with a free companion GitHub repo: all twelve, one folder per chapter, under the book's own filenames, with one command that drops the nodes and gates straight into a repo you already own.

Here's what you'll build:

1. A three node graph running on your own repository in ten minutes.
2. A fan out, verify and merge graph that turns one session into a parallel team.
3. 12 working systems, one per chapter, every one running on your own code.
4. A cross model verifier that rejects the answer self grading passes.
5. A routing log you can replay to prove why any branch fired, with no model call.
6. Shared state you can kill, inspect and resume from disk.
7. A scoped, priced, client-ready package built from your own metered numbers, worked end to end as a $3,000 fixed-fee deliverable.
