what do you mean by 'full system understanding', here? And don't you think that claude and openai are using their own forge as well?

Ingesting the whole codebase in their cloud and then maintaining indexes of where everything lives and what already exists. Not sure if that's where they are going but that's what I feel looking at some of the beta functionality and announcements.

For the forges, what the sibling said.

What forges are we talking about here? None of them have Github competitors.
