I think that his idea is that a lot of preparation / setup work is boiler plate / brain dead stuff that can be done by a shallower model.
It's like, find the relevant scientific papers by using Google search and the scientific paper MCPs, summarizing stuff, etc. Then the big model can come in and actually think on the artifacts
Big model can easily delegate to luna to do this task.
I ask task x -> big model thinks and delegate to luna heavy dumb work.
