GeminiCLI

Gemini CLI is the open-source AI agent that brings Gemini 2.5 Pro directly into your terminal for code generation, debugging, and complex task automation.

This open-source AI agent delivers Gemini 2.5 Pro power right to your command line, offering a 1-million-token context window for handling massive projects. It's built for developer productivity: using a reason-and-act (ReAct) loop, it executes tasks like fixing bugs or creating features. Core functionality leverages built-in tools (e.g., `grep`, `run_shell_command`, `web_fetch`) and is fully extensible via the Model Context Protocol (MCP). This ensures a unified, AI-first experience across your terminal and integrated development environment (IDE) via Gemini Code Assist.
