[Question] Harnesses for code review/tour features

[codythatsme]

Hey! Before raising PR's for something you might not want, I was wondering if there was any appetite for expanding the harnesses available for code review mode/code tour etc? Or any reason why only Codex and Claude are currently available here?

I would like to abstract out the "harness/provider" from the feature to make it a bit easier to extend other CLI's to tap into these features.
