This is just ai slop. If you follow what the actual designers of Claude/GPT tell you it flys in the face of building out over engineered harnesses for agents.
Works better than standard claude / gpt, which doesn't do red-green-refactor. Doesn't seem like slop when it meaningfully changes the results for the better, consistently. Really is a game-changer. You should consider trying it.
I agree with this. There is not a lot of harnesses/wrapping needed for Claude Code.
