This was Gemini CLI in kilocode. Does it often. Sometimes it even imagines that it's done a build when it hasn't - imagines build errors and then sets out to fix them. I have it set so that it asks permission prior to running commandline tools so I know it hasn't actually run make.

I use Gemini CLI daily (work is a Google shop), directly (no kilocode). I've never seen anything like that.

I wonder if it could be something to do with the kilocode integration.

But, I do more commonly run with permission required for many operations, because I find it works much better if I help it every now and then. It can get stuck on some pretty simple stuff.
