@soller I wonder if something like Claude could be used to write test programs based on the documentation, both to test the software and to check the documentation. For C programming, I'd put documentation in header files and use that instead of looking at my code. If I had to look at my code to see how to use it, I'd update/clarify the documentation, which then got better over time. It was more work at the start, but saved effort later and made the software easier for others to use.
