Hey everyone,

Like many of you, I've been playing with the new Google Antigravity IDE and Gemini 3.

I noticed that without strict prompting, the Agent tends to be a bit chaotic (creating files in random places, skipping tests, etc.).

So I built an opinionated Workspace Template that pre-loads the Agent with a "Senior Engineer" persona using the new .antigravity/rules.md system.

What it does:

• 🚀 Zero-Config: Just clone and open. The AI auto-detects the rules.
• 🧠 Deep Think: Forces Gemini 3 to output a  block before writing code.
• 📂 Artifact-First: Forces the AI to write plans/logs into an artifacts/ folder first.
• 🛠️ Ready-to-use: Includes Docker & Makefile.

Repo here: https://github.com/study8677/antigravity-workspace-template

It's fully open source (MIT). Would love to verify if this setup improves the "hallucination rate" for others too! Let me know what you think.
