README

@cortexkit/pi-antigravity-auth

Google Antigravity OAuth extension for pi. Authenticate with your Google account and use Gemini 3 models through Antigravity's endpoints.

[!CAUTION] Using this extension violates Google's Terms of Service. Accounts may be suspended or banned. This is an unofficial tool not endorsed by Google.

Install

pi package add @cortexkit/pi-antigravity-auth

Login

/login google-antigravity

A browser URL is shown. Complete the Google OAuth flow and paste the resulting callback URL (or authorization code) back into the prompt.

Models

The extension registers the Antigravity model catalog under the google-antigravity provider, including:

antigravity-gemini-3.5-flash
antigravity-gemini-3.1-pro
antigravity-claude-sonnet-4-6-thinking
antigravity-claude-opus-4-6-thinking

Select a model with /model or pi -m google-antigravity/antigravity-gemini-3.5-flash.

Configuration

Environment variable	Description
`PI_AGENT_DIR`	Override the pi agent directory (default `~/.pi/agent`).
`PI_ANTIGRAVITY_AUTH_FILE`	Override the account storage file path.

Notes

This package shares its transport, OAuth, fingerprint, and request-transform logic with the OpenCode plugin via @cortexkit/antigravity-auth-core. The current pi release targets a single authenticated account; multi-account rotation and quota gating are provided by the OpenCode plugin and are planned for pi in a later release.
