Right, but how does it know which files to pick? I'm curious if you're using a dependency graph or embeddings for that discovery step, since getting the agent to self-select the right scope is usually the main bottleneck.

I haven't found this to ever be the bottleneck, what agent and model are you using?

If you don't trigger the discovery agents, claude cli uses a search tool and greps 50-100 lines at a go. If discovery is triggered, claude sends multiple agents to the code with different tasks which return with overall architecture notes.
