It addresses the core problem of AI coding agents filling in unstated requirements with plausible-but-wrong assumptions. The tool outputs three sections — SPEC, PLAN, and TASKS — and marks every assumption it makes with [ASSUMPTION: ...] tags ranked by impact. The tutorial covers installation, invocation, how to read and correct assumptions, and how to hand the resulting spec to an agent as context rather than a prompt. The methodology, called Spec-Driven Development, has three levels: Spec-First, Spec-Anchored, and Spec-as-Source. ## Full article daily.dev links to this article rather than hosting it.
