🚀 Unlocking Gemini CLI: Create Powerful Custom Slash Commands Like a Pro

In today’s fast-paced development world, efficiency is key. Whether you’re automating tasks, managing tools, or optimizing workflows, the command line remains a developer’s best friend. And now, with Gemini CLI, you can take it to the next level by crafting your own custom slash commands.

In this post, we’ll explore what Gemini CLI is, how to create custom slash commands, and why it’s a game-changer for developers, system admins, and tech enthusiasts.

🔧 What is Gemini CLI?

Gemini CLI is a command-line interface tool designed to extend the traditional terminal experience with modular, customizable, and modern slash-based commands. Think of it like turning your terminal into a chatbot-style assistant — where you just type /build, /deploy, or even /joke and let Gemini handle the rest.

With Gemini, you’re not just running bash scripts — you’re creating intelligent command extensions with structured output, enhanced UX, and easy integration.

Step 2: Write Your Logic

module.exports = {
  name: "hello",
  description: "Say hello to the user",
  run: async () => {
    console.log("👋 Hello, developer! Ready to build something amazing?");
  },
};

Step 3: Run Your Command

/hello

Boom! Your terminal now understands your custom command. You can add prompts, variables, or connect it to real services.
