No model upgrade ships knowing your invariants; each generation raises fluency, not domain knowledge. The gap between the prompt you type and the prompt your domain requires closes one way: as a practiced, reviewed, team-level engineering skill. That practice is what this book teaches.
Each law names a structural truth about AI-assisted development — independent of model choice, stable across versions. The full treatment, with working examples in C#, Java, Python, and TypeScript, is in the book. Free, no email gate.
