It doesn't have a working plan mode.

If you ask it to plan something or suggest something. It'll write the suggestion and dive right into implementation with zero hesitation.

It's not my experience, but then I have a „living” GEMINI.md doc where I add/clarify/tweak what to do and what not to do. And it's possible the initial revision already contained the correct spell :)

gemini cli is such a trash it has ruined gemini 2.5 pro model's reputation, now people think it's incapable of writing good code.

True. In my experience, it has been good to use for second opinions and code reviews. Usually in CC/Codex via an MCP like zen.

Do not let Gemini CLI write code for you. You will find out the hard way

it sucks.

The opposite of my experience, but okay.

I'll give it another try, the gemini models themselves are great for me, tried the tool when it came out, didn't gel with it.
