Just wanted to introduce myself as the lead developer on the tool. Valid comments and questions have been dropped here and I've responded to a couple of them already by posting clarifications below and on the project wiki. Yes we are thinking of using the tool for repos like NuGet and maybe Github as a service that automatically identifies detected features for each component. Stay tuned and keep the ideas coming. Happy to answer any further questions.
I ran this against a file sharing application I am working on and the results were strange. Security features were supremely emphasized, even security concepts I didn’t realize I was focusing energy on. I am not saying the tool is wrong, but just that it picked security better than I had intentionally considered. No other features were highlighted though, so you still have no idea what the application is doing.
