The first is hard to test for us unfortunately since we don't use Cursor. But the Claude thing is interesting. I think that providers (especially the ones that directly sell LLM calls like Anthropic) are not incentivised per se to think about token efficiency vs performance, so if you're chasing pure performance, just loading the full codebase into memory might still be the "benchmark topping" way to go. I think the dust hasn't really settled yet and we'll likely see a lot of changes in the coming year about what's the "correct" way to solve it. It might be different based on your harness/budget/model as well.
