The Component Agent Framework for domain-Experts (CAFnE) toolkit is an extension to the Prometheus Design Tool (PDT). It uses the detailed design produced by PDT with further annotations by domain experts to automatically generate executable code into a desired agent platform. The key feature of CAFnE is that it allows domain experts with limited programming skills to easily build and modify agent systems.
