Spec-Driven Development: What decade of BDD teaches about AI
AI coding agents fail on ambiguity, not syntax. BDD solved that years ago with executable specifications in business language. This talk maps a decade of BDD practice onto spec-driven development with agents: scenarios an agent implements against, used as the acceptance gate, and how to catch false green when the agent writes its own tests. Examples come from real projects and from building an open-source ERP. The workflow fits any language.
