The Test Cabinet The Test Cabinet

Overview

Google Antigravity (slug antigravity) is a coding agent The Test Cabinet drives non-interactively like the other harnesses. It authenticates through a Google account alone, so it runs under subscription authentication and becomes available once the OAuth token its agy CLI writes is present. The harness itself is at antigravity.google.

Model IDs

Section titled “Model IDs”

The session arguments carry no model flag. Antigravity drives a Google-account session, so a run’s model ID reaches nothing in the CLI.

Invocation

Section titled “Invocation”

The harness probes and invokes the agy binary, installed into the run container at run time with:

Terminal window
curl -fsSL https://antigravity.google/cli/install.sh | bash

A single prompt is driven to completion with:

Terminal window
agy --print --dangerously-skip-permissions <prompt>

--print requests non-interactive output and --dangerously-skip-permissions suppresses the interactive approval prompts.

Authentication

Section titled “Authentication”

The harness authenticates from the Google-account OAuth token copied into the container. With no token present, the harness reports itself unavailable with a hint to sign in, and the run fails before a session is spent. See Authentication.
