The most useful architecture diagrams for me are context diagrams (process boundaries and interactions), sequence diagrams for important detail, and ER diagrams for databases.

This does not seem to create any of those, unless I am missing something. This seems to mostly speak to code dependencies. Which is useful, but probably not $300/month useful.

A typical architecture diagram will show you ingress points, API gateways and the like, where your app servers or web servers or whatever are, databases, eventing systems, etc and how they speak to each other. This doesn’t seem to do that, and it generally is not possible to generate such a thing automatically because there are too many dynamic pieces to track, or there are manual steps. Also, as others have stated, good architecture documentation requires thought and experience on what to highlight and what to omit or group together.
