A spec-first workflow for building with agentic AI

Agentic AI tools excel at autonomous software development but require proper context and structure to avoid hallucinations and inefficiencies, leading to the emergence of "spec-first" workflows where developers first create detailed project specifications before incrementally building features. This approach breaks projects into hierarchical agile-style tasks (epics, features, stories) that AI agents can tackle systematically, significantly improving productivity and code quality compared to ad-hoc AI development methods.
