Using Antigravity Provider in PicoClaw

This guide explains how to set up and use the Antigravity (Google Cloud Code Assist) provider in PicoClaw.

Prerequisites

1. A Google account.
2. Google Cloud Code Assist enabled (usually available via the “Gemini for Google Cloud” onboarding).

1. Authentication

To authenticate with Antigravity, run the following command:

picoclaw auth login --provider antigravity

Manual Authentication (Headless/VPS)

If you are running on a server (Coolify/Docker) and cannot reach localhost, follow these steps:

1. Run the command above.
2. Copy the URL provided and open it in your local browser.
3. Complete the login.
4. Your browser will redirect to a localhost:51121 URL (which will fail to load).
5. Copy that final URL from your browser’s address bar.
6. Paste it back into the terminal where PicoClaw is waiting.

PicoClaw will extract the authorization code and complete the process automatically.

2. Managing Models

List Available Models

To see which models your project has access to and check their quotas:

picoclaw auth models

Switch Models

You can change the default model in ~/.picoclaw/config.json or override it via the CLI:

# Override for a single command
picoclaw agent -m "Hello" --model claude-opus-4-6-thinking

3. Real-world Usage (Coolify/Docker)

If you are deploying via Coolify or Docker, follow these steps to test:

1. Environment Variables:
   • PICOCLAW_AGENTS_DEFAULTS_MODEL=gemini-flash
2. Authentication persistence: If you’ve logged in locally, you can copy your credentials to the server:

   scp ~/.picoclaw/auth.json user@your-server:~/.picoclaw/
   

   Alternatively, run the auth login command once on the server if you have terminal access.

4. Troubleshooting

• Empty Response: If a model returns an empty reply, it may be restricted for your project. Try gemini-3-flash or claude-opus-4-6-thinking.
• 429 Rate Limit: Antigravity has strict quotas. PicoClaw will display the “reset time” in the error message if you hit a limit.
• 404 Not Found: Ensure you are using a model ID from the picoclaw auth models list. Use the short ID (e.g., gemini-3-flash) not the full path.

5. Summary of Working Models

Based on testing, the following models are most reliable:

• gemini-3-flash (Fast, highly available)
• gemini-2.5-flash-lite (Lightweight)
• claude-opus-4-6-thinking (Powerful, includes reasoning)
