Antigravity 101: Managing Instead of Coding (The 3-Chat Workflow)

Most people think you need to be a developer to build a website, but the paradigm has shifted. In this Antigravity 101 guide, I’ll show you how to act as a manager instead. We’ll build a basic, responsive landing page in just three simple instructions—no technical skills required.

The goal isn’t just to build a site—it’s to understand how to talk to the AI to get the results you want.

The Manager Mindset vs. The Coder Mindset

When dealing with AI agents like Google Antigravity, the biggest mistake you can make is trying to micro-manage the code. If you are dictating div structures or CSS flexbox alignments, you are wasting the AI’s potential and your own time.

You need to step into the “Tech Dad” persona: patient, deliberate, and practical. You are not the coder; you are the manager. Your job is to define the problem, provide the requirements, and let the agent figure out the implementation.

To prove this, we built an entire functional website using the 3-Chat Management Workflow.

Chat 1: The Kick-off

The first chat is about creating the initial plan and structure.

Instead of jumping directly into the Editor Chat (which is optimized for coding), we use the Agent Manager (which is optimized for planning). We tell the agent what we want: a professional, responsive landing page.

The Agent Manager drafts an implementation plan. It asks clarifying questions. It thinks about Information Architecture before it touches any code. Once you approve the plan, it executes the foundational structure. In one chat, you go from an empty folder to a working scaffold.

Chat 2: The Visuals

A structural page is great, but it needs design. In the second chat, we leverage a hidden gem in Antigravity’s toolkit: Nano Banana Pro.

Instead of hunting for stock photos, you can prompt the agent to generate professional images instantly. This adds visual identity to your site without breaking your workflow. You just describe the aesthetic you want, and the AI handles the generation and placement of the assets.

Chat 3: The Polish

No initial build is perfect. The layout might break on mobile, or the margins might look off. This is where the manager mindset truly shines.

Instead of hunting through the CSS to fix a misaligned column, you simply tell the agent what is wrong. Let the AI agent “see” and fix its own layout mistakes automatically. In Antigravity, the AI has the context to troubleshoot its own work. You provide the feedback; the agent provides the fix.

Key Takeaways

1. Review-Driven Mode: The best Antigravity setup for beginners is to use the tool in a review-driven mode. Let the AI propose plans, review them, and approve them.
2. Manager vs. Editor: Use the Agent Manager for high-level planning and project structure. Use the Editor Chat for specific file modifications and debugging.
3. Patience: It rarely takes just one prompt. Expect to go through the 3-Chat cycle (Plan, Enhance, Fix) for every major feature.

By changing your approach from typing code to giving directions, you can build production-ready sites in a fraction of the time. Welcome to Antigravity.
