Specification-First Engineering: How Teams Are Scaling AI-Assisted Development

Spec-Driven Development emerged as the antidote to 'vibe coding'—the problematic practice of loosely prompting AI and deploying whatever it generates. As AI agents handle more code generation, specifications become the highest-leverage artifact teams produce, shifting skill emphasis from implementation to intent definition. The spec-anchored maturity level offers immediate production value by keeping specifications and code synchronized through automated testing.
