Spec-Driven Development (SDD) is the brave new world in AI coding we all knew was inevitable. More like a revolution than an evolution of software delivery, SDD produces solutions as artifacts of a structured specification. This specification is the contract for code behavior and the single source of truth guiding developers, tools, and AI agents to generate, test, and validate results. It is software engineering through prompt precision.

You’ll see a walkthrough of Spec-Driven Development (SDD) in action with GitHub Spec Kit. I’ll show how the Specify CLI kicks off a project by generating spec templates, plans, tasks, and even a “constitution” doc. You’ll see how the templates are structured, how the slash commands (/specify, /plan, /tasks) actually work, and how AI agents use them.

You’ll see trade-offs and design alternatives play out in real time, comparing libraries, infrastructure, and approaches, directly from the spec. And you’ll see how this cuts down rework, keeps teams aligned, surfaces the “why” early, and helps AI agents deliver results you can trust.
