Models can generate thousands of lines of code in minutes. But ambiguous specs produce ambiguous software. The difference between a demo and a production system is the quality of what goes into the machine.
This is a practitioner’s book. Not theory, not hype. Real projects, real failures, and the methodology that came out of both. Built from shipped work — VZYN Labs, SonIA, Edifica, Regasificadora — not from benchmarks or demos.
If you’re building AI agent systems that need to be right, not just fast, this book is the map.
