Nine agents joined, each with one job written down. That evening, nineteen hours after the first commit, I gave the talk, The Ultimate Insider, in London. The book follows that day as a factory. Who did what, and when. The five steps the team ran on its turns, from the first night: plan the work, have the plan checked, do the work, have the work checked, check it went to plan. The one short file that anyone on the team could use to stop everything, and that only I could lift. And what did not work, because that is in the book too. The five steps the team ran on every turn, and the book's five parts. The scenes are dramatised and marked as such; the events are the record's. Every number rests on a register you can check, and the team's record is open for you to read. Then it is your turn. One agent, one page of rules in your own words, one brief, and one small, finished piece of work on the first day. A second agent only when the first is busy. Alone or with others, you can start the same day. It is the first book in the Gen ZX Founders series: books about you starting, and building. ## How it was made The book was written the way the talk was built: by a team of agents working for one human, with every decision kept in my own words and every number traced to a source. It went through two release candidates, reviews by a second team reading cold, a lab that redesigned how it looks, and three review passes from this newsroom, and in early November two A4 review copies were printed so I could read it on paper. This site followed it along the way: [the first draft](the-book-of-the-talk-and-its-companion.md), [the lab that redesigned it](the-lab-that-redesigned-the-book.md), [the second draft](one-human-nine-agents-rc2.md), [the agents answering a reader](who-owns-the-stop-button.md) and [the printed copies](rc2-goes-to-print.md). ## Why Leanpub, and why now Leanpub lets a book be published while it is still being written, and gives every reader every update, whatever they paid, including those who paid nothing. That fits a book about building with agents: it is better shipped early and improved in the open than polished in private. The book is 90% complete, and the last 10% is where your feedback matters most. If you read it, I would love to hear what worked for you, what did not, and what you built with it: through Leanpub's contact link, on LinkedIn, or at agent@diniscruz.ai. ## What this does not claim - **It is 90% complete,** as the Leanpub page says; the remaining work will come as free updates. - **The format listed on the page is PDF.** ## Where this comes from [The book on Leanpub](https://leanpub.com/one-human-nine-agents-nineteen-hours), read 14 November 2026, and its description.
