antigravity full guide from install to custom rules workflows and mcp

Google Antigravity isn’t just another code editor with an AI sidebar. Launched on November 18, 2025, it’s an agent-first development platform that fundamentally changes your role from a coder to an architect and manager of autonomous AI agents. This is how Google see the collaboration between software engineers and AI, in all aspects: Army of Agents, and humans as an architect of that. Thanks for reading Code Meet AI: Stay relevant in the AI era! Subscribe for free to receive new posts and support my work. Getting started is straightforward.

The platform is currently in a free public preview for personal Gmail accounts . Download: Go to the official Antigravity download page and get the installer for your operating system (Windows, macOS, or Linux) . Google Antigravity was announced last week as the next generation agentic IDE. I’m very impressed with it so far. It already helped me to upgrade my blog to the latest Hugo (that I’ve been putting off for a long time). It even recognized that some of the shortcodes (eg.

Twitter) from the old version changed in the new version and automatically updated my blog posts with the new version of the shortcodes. Nice! There are many blog posts on how great Antigravity is and also a codelab. Once you get over the hype of Antigravity, you’d want to customize it to make sure it behaves exactly as you want. That’s the topic of this blog post. Antigravity comes with a couple of customization options that you might not be aware of.

If you click on the ... on the top right corner and choose Customizations, you will see Rules and Workflows as two customization options: Rules help guide the behavior of the agent. These are guidelines you can provide to make sure the agent follows as it generates code, tests, etc. For example, you might want the agent to follow a certain code style, or to always document methods. You can add these as rules and the agent will take them into account.

Workflows are saved prompts that you can trigger on demand with /, as you interact with the agent. They are similar to Rules in the sense that they also guide the behavior of the agent but they’re triggered by the user on demand. In this codelab, you will learn about Google Antigravity (referred as Antigravity for the rest of the document), an agentic development platform, evolving the IDE into the agent-first era. Unlike standard coding assistants that just autocomplete lines, Antigravity provides a "Mission Control" for managing autonomous agents that can plan, code, and even browse the web to help you build. Antigravity is designed as an agent-first platform. It presupposes that the AI is not just a tool for writing code but an autonomous actor capable of planning, executing, validating, and iterating on complex engineering tasks with minimal human intervention.

Currently Antigravity is available as a preview for personal Gmail accounts. It comes with a free quota to use premier models. Antigravity needs to be locally installed on your system. The product is available on Mac, Windows and specific Linux distributions. In addition to your own machine, you would need the following: If you’ve used Google’s new Antigravity IDE since it dropped in November 2025, you know it’s not just another VS Code fork.

It’s a paradigm shift. We aren’t just completing code anymore; we are orchestrating it. Antigravity introduces an “Agent-First” workflow that feels less like typing and more like managing a small team of engineers. But if you’re still using it like a standard editor — just hitting tab for autocomplete — you are leaving 90% of its power on the table. After a few weeks of heavy usage, here are a few advanced tips. The “Agent Manager” isn’t just a fancy history tab; it’s a parallel processing engine.

Most beginners wait for one agent to finish a task before starting another. Don’t do this. Antigravity allows you to spawn multiple asynchronous agents effectively. You can have Agent A refactoring your messy legacy authentication module while Agent B is simultaneously writing a Jest test suite for the current version of that same module to ensure backward compatibility. Master Antigravity with proven best practices. Learn prompt engineering, workflow optimization, code quality, security, and common mistakes to avoid.

Master Antigravity with proven best practices from experienced users. This guide covers prompt engineering, workflow optimization, error handling, code quality, and team collaboration. Why it's bad: Agent makes assumptions about fields, validation, styling Fix: Specify all requirements explicitly Mistake: Clicking "Proceed" without reading the plan Google just announced Gemini 3 Pro and the Antigravity release.

I am actually more excited about Antigravity because of Varun Mohan. I have been a big fan of Windsurf, and I had a feeling from the start that once Varun joined the team, something amazing would arrive. And here we are with Antigravity. I have been experimenting with it for the past few hours and here are my thoughts: Google Antigravity is a new Agentic development platform from Google that changes how software is built by letting developers work at a higher task-focused level. With the reasoning and Agentic coding abilities of Gemini 3, Antigravity allows AI Agents to plan, code, and validate complete software tasks on their own.

It includes an Agent manager dashboard, a VS Code-style editor, and deep browser connectivity, letting Agents interact with web apps directly for testing and validation. Instead of being just another coding tool, it becomes a true development partner that improves productivity by managing multiple projects and tasks in parallel with autonomous workflows.

Here’s a step-by-step guide on how to add Global Rules (with screenshots): Here are some useful Global Rules you might want to set:

You can easily convert your existing Cursor project rules to Google Antigravity format. For example, I’ve converted my Cursor project rules for Vue 3 frontend development into Google Antigravity project rules. Download link: https://www.lanxk.com/files/GEMINI-project-rules-for-vue3-en.md
