Interesting.is this product of yours? Have you used it on a larger engineering team? I'd be interested to know whether it actually reduces onboarding time or improves AI-generated code in practice.
I haven't done formal evals in this AI era about how having a concept map alongside the codebase changes what the agents do, but informally I know mine read them because I tell them to and they seem to take it into account, and I seem to have less trouble than the average geek I talk to keeping my code base adequately coherent. It's just plain text context, after all so there's no magic, just very concise and accurate context.
