+1 I have not found Gemini 2.5 better than Claude's latest models -- different and better at some things, but not better in general; and in general I have found Gemini 2.5 Pro to be worse at dealing with large codebases despite its huge context window. So I too am quite curious about the workflow here.
the core idea is to not use up all of context for files but instead sessions go longer before becoming a useless pursuit ie. more turns possible with larger context window
