Could Gemini CLI be used for PR reviews? For example, would you expect that asking Gemini to compare two git commit hashes and analyze the code changes for potential bugs/conciseness/adhesion to the idiomatic project style, etc. to work well?

Edit: I tried it. The setup was a breeze. I fed the CLI two git commit IDs and some light prompting on what to look for. It gave a reasonable response. I'll try on a real PR shortly.
