Overview

This codelab introduces Gemini CLI, Google’s open-source tool that brings Gemini models into the terminal. You’ll start with three setup modules to understand what Gemini CLI is, why it exists, what powers it, and how to install it. Then, you’ll dive into five practical use cases that demonstrate real developer workflows: automating code reviews, integrating with CI/CD pipelines, generating and running complex shell commands, creating documentation and tests, and building small agent-driven task flows. Along the way, you’ll see how Gemini CLI translates natural language into actionable commands, integrates with tools like GitHub and Google Cloud, and reduces context switching in everyday development. By the end, you’ll know how to extend Gemini CLI with custom slash commands and use it as an AI-powered assistant to boost productivity directly in your terminal.
