Testing the Antigravity CLI Environment
Once you have the package installed — you can test the startup of Antigravity CLI. You will need to authenticate with a Google Project or your Google Account:
Then step through the process:
And finally the One time code:
Initial Configuration
Once you have installed and authenticated. Step through initial configuration:
Are we There Yet!?!?
If all the stars align and you do the correct sacrifices to the pagan Gods then at this point you should be able to start up the agy CLI and get down to business.
Instead of gemini the startup command is agy:
xbill@penguin:~$agy
All Right Already! Can you actually do something with Antigravity CLI?
Fire up that terminal window and get to work:
> what can I do at Google I/O ?
▸ Thought Process
Considering User Intent
Depending on your developer focus, you can tailor your Google I/O experience into a specialized
learning journey. Here is a breakdown of the core developer pathways and exactly what you can do
in each:
──────
### 🚀 Journey 1: The AI & Agent Developer
If you want to build intelligent, autonomous, and highly context-aware systems:
• Master Gemini 3.5: Explore the latest APIs to leverage massive context windows, multimodal
inputs (text, image, audio, video), and enhanced coding capabilities.
• Develop with Antigravity 2.0: Learn how to use this new agent-first development platform to
build autonomous, goal-oriented systems that can run multi-step reasoning workflows directly in
production.
• Integrate Firebase Genkit: Dive into sessions showing how to build, test, and run AI-powered
features using TypeScript/JavaScript or Go in a developer-friendly framework.
### 📱 Journey 2: The Mobile & Spatial Developer
If you build apps for phones, tablets, foldables, and wear:
• Design for Android XR: Start building immersive, spatial experiences for upcoming smart
glasses and headsets using your existing knowledge of Kotlin and Jetpack Compose.
• Adopt Kotlin Multiplatform (KMP): Learn best practices for sharing business logic, networking,
and data storage between iOS and Android.
• Implement On-Device AI: Watch deep dives on using Gemini Nano locally on Android devices to
handle tasks like smart replies, summarization, and translation without requiring network calls.
### 🌐 Journey 3: The Modern Web Developer
If you are dedicated to building fast, beautiful, and accessible web applications:
• Build with Built-in Browser AI: Discover how to utilize Chrome’s new built-in AI APIs
(leveraging local on-device models) directly within your web apps.
• Leverage Modern CSS & Web Performance: Explore upcoming browser APIs, new layout models, and
how to track modern Core Web Vitals to deliver ultra-premium web experiences.
• Rely on Baseline: Learn how the "Baseline" initiative makes it easy to identify which modern
web features are universally supported across Chrome, Safari, Firefox, and Edge.
### ☁️ Journey 4: The Cloud & Backend Engineer
If you manage deployment, scalability, and developer workflows:
• Deploy with Firebase App Hosting: Try out the next-generation hosting platform that
automatically detects, builds, and deploys server-rendered frameworks like Next.js, Angular, and
Nuxt.
• Scale AI Workloads on GKE: Learn how to optimize Kubernetes for high-performance AI inference
and custom model fine-tuning.
• Utilize Vertex AI Agent Builder: Build enterprise-grade agents grounded in private data
sources with zero machine-learning experience required.

### How to Take Action Now
1. Bookmark your path: Go to the Google I/O Session Catalog https://io.google/2026/program/ and
filter by your chosen pathway.
2. Access Codelabs: Go to io.google/codelabs https://io.google to access step-by-step
programming tutorials for all these new technologies.
3. Engage with Google Experts: Visit the digital developer forums or official Discord channels
to ask questions and discuss lessons with the engineers who built these products.

Summary
Antigravity CLI was introduced as a compliment to the existing GUI based IDE versions.Some transition information was provided for Gemini CLI users. Antigravity CLI was then installed from the official Google sources. A sample query was tested and some common slash commands were highlighted.
Good-bye Gemini CLI- it was nice to know you! Hello Antigravity CLI- I am sure we can be friends! When one door closes- another one opens.
