Made a CLI that can query GPT5 Pro. In my experience that's the smartest model. Very convenient to use as an "oracle" when coding agents like Sonnet 4.5 get stuck or need guidance.
I started writing a TUI coding agent last week and this `/explain` feature is the first one that's really sick. Gives you a tutorial about current branch relative to master. Will add many more bells and whistles but this is already amazing.
