This is why open harnesses and open models will always be superior, it's only a matter of time until someone decides that something you use isn't worth maintaining anymore. The reply from the Anthropic employee up above doesn't give me much confidence that Claude users will be able to continue using plan mode forever.
The flexibility and lightweight nature of open harnesses is mainly useful for open models. These models are considerably far behind the frontier and need a lot more steering. Complex harnesses confuse them. I use open harnesses for my OSS model rig because the model needs it.
Even if I agreed, that doesn't address my point: Claude Code might be the world's best harness right now, but that doesn't stop an Anthropic employee coming along tomorrow and taking a giant steamy dump on the thing you like most about it. You're using their workflow, not your own.
