I came to a similar conclusion. I think the default options in many IDEs (Ask/Plan/Agent) are limited... 'Refine' feels like an improved 'Plan' in that it doesn't just jump right into building a list of tasks based on the initial prompt, because who knows what sort of flaws or deficiencies were present in the initial prompt! Can't always get everything right in the first try. XP

I don't think a specific harness is even necessary to get a boost from 'Refine'. Even a simple custom agent is portable enough... it's easy enough to take the existing 'Plan' agent definition present in VS Code and tweak it to be 'Refine' instead.
