Stop Writing Prompts. Start Writing Specs.

Microsoft Developer (Build) · Aug 24, 2026 · Engineering Insights

Enterprises should replace prompt-first AI coding with specification-driven development practices.

“Stop treating the prompt as the main artifact and start treating the specification as that main artifact.”

A Microsoft partner architect argues that prompt-first AI coding is too fragile for enterprise teams — prompts are private, temporary, and hard to review. The proposed alternative is spec-first development: a layered system of a 'constitution' (unbreakable rules like security standards) plus a functional specification that guides AI agents. The talk demonstrates this workflow using GitHub Enterprise, GitHub Copilot, and a GitHub tool called 'specit'.
