In moldable development, I build lots of tiny tools. Together, they help me grow my understanding of a system. Here (Visual Studio Code) we can clearly see that different people do different things in a project . Less than 30 lines of code in this case. Using a domain specific language for visualizations, with nodes, edges and layouts. And tiny is important, because that makes them fast to write and easy to understand.
Do you need more understanding of your system? Let me know if I can help.
