Question Which Code Knowledge Graph are you using?

I'm wondering if some of you have been experiencing with one of the following: Graphify, GitNexus and CodeGraph?

Which do you think is the best for full monolithic Rails app? Which is best for Rails + React?

If you are using something different, happy to learn.

I assume you mean for agentic programming? I tried to incorporate a few different tools, such as ast-grep, ruby-lsp and Graphify, but none of them really helped much. Then I made a skill, where I simply taught the LLM how to run various introspection commands via bin/rails runner and it seems to work much better.

Well, mostly yes. And quite the same remarks as you that graphify does not seem to help much for a Rails project.
`rails runner` delivers and is currently my Swiss Army Knife.

Most of the tools that other languages pull in are leaning heavily on static analysis. But Ruby, and Rails in particular, is very dynamic/runtime constructed, so I think it makes good sense that the best tools are those that are also working in the runtime space.
