Built on the Boundary-Control-Entity pattern, it uses standard notations (EARS requirements, JEP 467 Markdown JavaDoc, Mermaid) to keep specs in stable public formats already known to LLMs. The workflow ships as an AIrails skill in roughly 4,000 tokens. Two commands drive it: /sbce new declares a capability and scaffolds layers, while /sbce apply converges code to the spec by generating missing methods and tests, surfacing undeclared code as drift. Done means a green test run, not the model's opinion. ## Full article daily.dev links to this article rather than hosting it.
