Written for people who have to make decisions about AI systems rather than train them from scratch. No prompt templates, no mathematics, no code. The mechanism, the failures it makes inevitable, and what actually reduces them.




Understanding the machine before you build on it.
An airline was ordered to pay for a refund policy its chatbot invented. A legal brief cited six court cases that did not exist. Neither failure looked like a failure. Both read like every correct answer the system had ever produced.
This is a short book about why that happens, what it costs, and where the leverage actually is. Not prompts. Not tools. The environment you build around the machine.
The first book is the foundation. The work that follows extends it into the parts that decide whether a system survives contact with real users.
Told first when a new book is ready, alongside new writing on building AI systems that hold up in production.
Applied AI and systems design. Writing and advisory on the distance between a demonstration and a system people depend on.
