Pure flour-power. Hearty enough to carry you through lunch.
Summary
This article explores the emerging concept of Spec-Driven Development (SDD), an AI-assisted programming approach where developers write detailed specifications before coding. The author examines three SDD tools - Kiro, spec-kit, and Tessl - to understand how this methodology works in practice. SDD positions specifications as the central source of truth for both human developers and AI assistants, representing a shift toward documentation-first development in the AI coding landscape.
