Google Gemini CLI

Google Gemini CLI is the open-source AI agent that brings Gemini models directly to your terminal for coding, problem-solving, and task automation.

The Gemini CLI is your command-line AI assistant: an open-source agent that executes complex tasks using a Reason and Act (ReAct) loop. It integrates Gemini models, including Gemini 3 Pro and Gemini Flash, directly into your workflow. Install it globally via `npm install -g @google/gemini-cli` and authenticate with your Google account. The agent utilizes built-in tools like `grep`, `terminal`, `file read/write`, and `Web search` to operate on your local environment. This capability makes it highly effective for developer tasks: fixing bugs, generating unit tests, explaining codebases, and automating feature creation.
