AWS Cloud Shell with Antigravity CLI

This article covers the initial setup and configuration for the Antigravity CLI on the AWS Cloud Shell. Why? Sometimes you need more than one Cloud!

What is Antigravity CLI?

The Google Antigravity CLI is a lightweight Terminal User Interface (TUI) that allows developers to invoke, monitor, and interact with Google Antigravity AI agents directly from the command line. It pairs with Antigravity 2.0 to offer the same core agentic capabilities — like multi-step reasoning, tool calling, and sub-agents — without the overhead of a desktop application.

Amazon Cloud Shell

AWS CloudShell is a browser-based, pre-authenticated terminal that allows users to securely manage, explore, and interact with AWS resources directly from the AWS Management Console. It comes pre-installed with the AWS CLI, popular programming languages (Python, Node.js), and developer tools, removing the need for local configuration.

The full background information on the Cloud Shell is here:

Browser-based Shell - AWS CloudShell - AWS

Why would I want Antigravity CLI on AWS? Isn’t that a Google Thing?

Yes- Antigravity CLI leverages the Google Gemini models but it is also platform agnostic. Many applications are already cross-cloud so this enables familiar tools to be run natively on Amazon AWS.

Activating Amazon CloudShell

The AWS CloudShell comes preinstalled on all AWS Accounts.

To access the shell — click the Terminal Icon in the upper right hand corner of the console:

Then activate the full shell:

Note- the disk space in the environment is limited to 1GB.

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.

The startup command is agy:

agy

All Right Already! Can you actually do something?

Fire up that terminal window and get to work:

> what does the aws command line tool do?

  The AWS Command Line Interface (AWS CLI) is a unified tool that allows you to manage and control Amazon Web Services
  (AWS) directly from your terminal or command-line shell.

  Instead of clicking through the web-based AWS Management Console, you can interact with almost all AWS services by
  running commands.

  ### Key Capabilities

  • Service Management: You can provision, configure, and delete AWS resources across services like Amazon S3 (storage),
  Amazon EC2 (virtual servers), DynamoDB (databases), IAM (identity/access management), and more.
  • Automation and Scripting: Because it runs in the shell, you can write scripts (using Bash, Zsh, or PowerShell) to
  automate complex tasks, deployments, backups, and resource monitoring.
  • API Integration: The CLI is a wrapper around the AWS REST APIs. It handles request signing, authentication,
  pagination, and output formatting (supporting JSON, YAML, text, or tables).

  ### Basic Command Structure

  AWS CLI commands follow a standard pattern:

    aws <service> <operation> [options-and-parameters]

  ### Common Examples

  1. List files in an Amazon S3 bucket:
    aws s3 ls s3://my-bucket-name

  2. Upload a file to Amazon S3:
    aws s3 cp document.pdf s3://my-bucket-name/

  3. List running Amazon EC2 instances:
    aws ec2 describe-instances --filters "Name=instance-state-name,Values=running"

  4. Get the identity details of the current CLI user/role:
    aws sts get-caller-identity

Summary

Antigravity CLI was introduced as a compliment to the existing GUI based IDE versions. Antigravity CLI was then installed from the official Google sources to the AWS Cloud Shell. Sample AWS specific querys were tested and some common slash commands were highlighted.
