Gemini CLI

Gemini CLI is an open-source command-line tool that brings Google’s Gemini models into your terminal. It supports code generation, editing, project scaffolding, multimodal input, tool execution, and slash-command workflows. You can use it to summarize code changes, query large codebases, refactor code, automate rebases, or even create apps from PDFs and sketches.

Key features include:

• Custom slash commands via TOML files
• MCP integration with /mcp commands and tool discovery
• OAuth, Vertex, and API key authentication
• Shell passthrough (!), file injection (@), and vim-mode editing
• Full local config and memory override support via GEMINI.md files

Gemini CLI is highly extensible, supports CI/CD workflows with headless auth, and includes built-in privacy, telemetry, and version controls.
