Add support for other agent cli

Hey,
it would be awesome if Radar would support other clis, namingly opencode, codex, antigravity, pi for AI investigation.

Absolutely - we shipped with an initial set we thought would be most common and that the CLI can provide a good experience. The goal is for broad support.

Happy to get contributions if someone is willing to pick it up - there's a decent abstraction now that 3 are supported, so adding more shouldn't be too hard.

Note - from your list codex is supported already. If you're not seeing it that's a bug, LMK

Thanks for the reply! actually yes. i do not see any mention of codex. I do not have codex installed, if there is an auto detection, that would be the reason. If not, it's a bug.

ah yes, it's auto-detection - shows you only the CLIs we found. We considered adding a hint. I guess at least here in settings this is an obvious place to do it. Will do a quick fix for this
