Gemini CLI Joins the AI Toolkit-What You Need to Know

Gemini CLI is an AI-powered command-line tool developed by Google that understands your code, connects with your tools, and helps automate complex workflows. Built on top of Gemini 2.5 Pro, it can analyze large codebases, generate apps from files or drawings, manage pull requests, and even help create media content.

In simple terms, it’s like having a coding assistant, project manager, and AI researcher, all in one tool you run from your terminal.

Let’s say you want to understand all the content of the PDF documents stored in your directory:

cd my-new-project/
gemini
> Help me understand the PDF in this directory. And also provide a summary of the documents.

Or maybe you’ve just cloned a large repo and you want to understand the large codebases instantly.

cd some-huge-repo/
gemini
> Describe the main architecture of this system.

Gemini will read your codebase and give you a clear, human-readable overview. You won’t have to scroll through files trying to make sense of it all. Furthermore, Gemini can interact with your system to automate repetitive tasks.

It’s like having a junior developer on your team 24/7.

We’re entering a new era where AI tools don’t just answer questions, they take action. Gemini CLI bridges the gap between your workflow and AI assistance. It’s multimodal, meaning it can understand not just code but also PDFs and sketches. You can use it to generate full-stack apps, analyze system architecture, and even automate internal reports.

And the best part? It works in your terminal. No extra GUI, and no context switching.

Make sure you have Node.js version 20 or higher installed.

Run via:

npx https://github.com/google-gemini/gemini-cli

Or install globally:

npm install -g @google/gemini-cli
gemini

Authenticate with your Google account or Gemini API key. You’re now ready to query Gemini right from your shell.

Gemini CLI feels like the future of developer tools, context-aware, prompt-driven, and deeply integrated with your workflow. Whether you’re trying to save time, understand your project better, or just want an AI-powered command line assistant, Gemini CLI is worth a try.

“Describe the architecture.”
“Build a bot.”
“Summarize yesterday’s code.”

Just type it. Gemini does the rest.
