Over the weekend I vibe-coded a POC workbench for Responsibility-Driven Design that incorporates a workflow I teach in my workshops. Specs -> CRC cards -> Sequence Diagrams -> Class Diagrams (optional) You can play with it here. Offered without any warranty or support. I got tired in remote workshops of saying "Capture your specs in this tool, then model CRC cards in this tool, then draw a sequence diagram in this tool, etc". https://codemanship.co.uk/rdd/
