This book shows how to build AI agents that do work while you sleep. It starts with one task you hand over. It ends with an organization that has a goal nobody has to restate every morning, a budget that can run out, and a memory.In between are the patterns, and they are not about buttons and not about technology. They are about the order in which you work. Which move makes the next one cheap. Why checking has become more expensive than making, how to have a machine check its own work, and where the brake belongs before you hand over the power to act.The unusual part is not the speed. It is that it got easier every day instead of harder — and that came from a small number of moves that looked like nothing on the day itself.Every chapter carries an instruction you can run yourself on the administration that comes with the book, with what goes wrong and how to correct it. Everything in it happened and can be checked, including what went wrong and what it cost. And you do not have to be a programmer: one of the chapters is about precisely that objection.You are not late yet. But that will not last.
