We opensourced our claude code ui today: https://github.com/bearlyai/openade

I wanted a terminal feel (dense/sharp) + being able to comment directly on plans and outputs. It's MIT, no cloud, all local, etc.

It includes all the details for function runs and some other nice to haves, fully built on claude code.

Particularly we found planning + commenting up front reduces a lot of slop. Opus 4.6 class models are really good at executing an existing plan down to a T. So quality becomes a function of how much you invest in the plan.
