The shortcut tax

Agents are fast. That is exactly why teams pay a shortcut tax: mock data that never gets replaced, silent failures, tests that assert the wrong thing.

Prep as a system

Prep-first work means: clarify the goal, name constraints, gather references, then prompt. The model does synthesis — you own the specification.

typescript
type Task = { goal: string; constraints: string[]; done: (out: unknown) => boolean }

What changes on teams

You review specs, not vibes. You measure whether the output is testable, observable, and aligned with production rules — the same bar you would use without AI.
