Pointing GOOGLE_GEMINI_BASE_URL at Your Own Gateway Does Not Change Who Holds the Key
I pointed the Antigravity CLI at a gateway of my own and recorded exactly which credentials travelled with it. Authorization is dropped across a cross-origin redirect, but the API key header survives every hop. Here is the measurement, and how I moved the key off my laptop.
Running Antigravity CLI 1.1.13 on a Machine You Cannot Sign In From
I put agy on a box with no browser and the sign-in screen stopped me cold. Here is how direct GEMINI_API_KEY auth from CLI 1.1.13 works, how to confirm it took effect, and why you should not hand it the key your app already uses.

Telling Apart AI API 429s, Auth Errors, and Timeouts: Recovery Steps by Symptom
How to read 429, 401/403, and timeout failures from the OpenAI, Gemini, and Claude APIs, with retry, rate-limiter, and streaming code, plus the line I draw to keep them from coming back.
When Antigravity Sign-In Stalls: Six Symptoms, and the Folder You Shouldn't Delete
Stuck on 'Setting Up Your Account', hitting a 429, a Google account that isn't recognized, or a passkey prompt that never finishes. Here is how to tell which stage is failing, and how to back up your settings folder instead of deleting it.
Antigravity Now Saves OAuth Tokens to the OS Keyring — Keeping Auth Alive in Headless Runs
In v2.2.1, refreshed OAuth tokens are saved to the OS keyring automatically. Pleasant on the desktop, but on headless scheduled runs the vault itself may not exist and auth quietly breaks. We design explicit backend selection, a safe file fallback, and per-location liveness checks.
Rotate Keys Without Stopping an Unattended Agent: An Overlap-Window Design
API keys and tokens are worth rotating on a schedule before they leak. But an unattended agent goes quietly dead the moment auth breaks during the swap. As an indie developer running several sites on autopilot, I lay out an overlap-window design that rotates keys without downtime.
When the Antigravity CLI Stalls on a 401 During Unattended Runs
If your scheduled Antigravity CLI job suddenly stops producing output after a single 401 in the logs, here is how to separate an expired token from a silent re-login prompt and rebuild your unattended setup.
