Gemini CLI helps you review code, analyze plans, and process big files. It works well for tasks that need a large amount of text, like whole codebases or long documents. You choose a model and let Gemini do the work.
This tool is great for developers who want a thorough code review across many files. It can also check architectural plans or project roadmaps. The default model is Gemini 3 Pro, which gives top results for reasoning and coding.
When you run Gemini in the background, you must use a special approval mode so it does not get stuck. The skill tells you exactly which commands to use. After the analysis finishes, you can start a new session for follow-up questions.
