It’s interesting you mentioned that. One of the things I’ve started doing recently is throwing a large LLM such as codex-5.3 (highest level of reasoning) at some of the more complex systems we have to produce nicely formatted ASCII diagrams.

I still review each diagram afterward, but the great thing is that, unlike image-based diagrams, they remain fully text-readable and searchable. And you can even expose them as part of the knowledge base for the LLM to reference when needed going forward.
