Spec-Driven Development: The Rise of Builder PMs

Code got cheap. Clarity hasn't. AI coding agents can now build almost anything you describe. The old bottle neck of writing code is gone. The new one is saying what to build clearly enough that an agent builds the right thing. This is the shift behind spec-driven development. Instead of prompting an agent and hoping, teams write a spec first: the behavior, the constraints, and what "good" looks like. The agent builds against it. In a world of disposable code, a long-lived spec becomes the artifact that matters most. Product managers have always turned ambiguity into something a team can ship. The PRD is used to align people. The spec aligns people and agents. This is the rise of the Builder PM: a product leader whose judgment is precise enough to direct a fleet of agents.
