A conference talk from NDC Copenhagen 2026 exploring spec-driven development using GitHub's SpecKit toolkit. The speaker, a .NET MVP and consultant, argues that agentic and vibe coding boost implementation speed but neglect product understanding and requirements clarity. SpecKit is an open-source (currently v0.8 preview) toolkit that structures AI-assisted development into five phases: constitution (non-functional requirements), specification (functional requirements with user stories), planning (technical architecture), task generation, and implementation. A live demo builds a single-player Pong game in Blazor using GitHub Copilot as the agent, showing how the process generates markdown-based specs, plans, and code. The speaker also covers reverse-engineering specs from brownfield codebases, customization hooks, and token cost trade-offs, concluding that the approach is particularly valuable in requirements-heavy domains like healthcare and insurance.
