News Summary

• UseCaseAPI gives internal application use cases stable, versioned contracts.
• It helps teams and AI coding agents see what can be called, what can fail, and whether a change broke an application-layer contract before that break ships.
• It is designed for applications with many internal use case nodes: workflow-like systems, AI-agent tool surfaces, CLIs, batch workers, FastAPI/Django backends.
• It does not add HTTP, RPC, serialization, service locators, dependency injection containers, or transaction managers to your application.
