The AI engineer works at the boundary between rented intelligence and specific work. The model ships on a six-week cadence and its cost halves on a schedule, so the book's center is the loop: persistent context, delegation and triggers, with a human setting direction in the outer cycle.
Measurement is the hardest problem. Reward hacking, specification gaming and judge exploitation are one literature about one problem, Goodhart's law. The defense is a frozen suite the loop cannot see: sixty to a hundred real cases, signed by the owner of the standard, before the build.
Persistent context, delegation and triggers run an inner execution cycle while a human sets direction in the outer one.
When a measure becomes a target, it ceases to be a good measure. The book separates reward hacking, specification gaming, judge exploitation, contamination and sandbagging.
Real cases, adjudicated, frozen before the build, held out of the loop, versioned and append-only, and model-agnostic.
