What it does

Enables Opencode to authenticate with Antigravity using Google OAuth, allowing access to models like gemini-3-pro and claude-opus-4-5-thinking with Google credentials

When to use it

•When you want to use Opencode with Antigravity models like gemini-3-pro
•When you need to access claude-opus-4-5-thinking with your Google credentials
•When you want to leverage Antigravity rate limits with Opencode

Ready-to-paste prompt

Use the following command to authenticate with Antigravity: npm run start -- --clientId YOUR_CLIENT_ID --clientSecret YOUR_CLIENT_SECRET

Heads up: Make sure you have a Google OAuth client ID and secret set up in the Google Cloud Console and added to your .env file, as the authentication process will not work without them
