Gemini CLI is really bad. Yesterday, I tried to make it fix a simple mypy linting issue, just to see whether it has improved since the last time I tried it. I spent minutes amused watching it fail and fail again. I then switched to Aider, still using Gemini 2.5 Pro model, which instantly resolved the linting problem.

While Gemini 2.5 Pro is good, I think Gemini CLI's agent system is bad
