It looks like Google, following Anthropic, is trying to restrict its subscription-plan models to its own harness only, making it harder to use those credentials in third-party AI agents.

 A week ago in a discussion there were reports of Google accounts being blocked for using Antigravity via third-party tools. Google explicitly calls using credentials in a third-party tool a ToS violation that can lead to account blocking. There is a separate comment from a user whose access was blocked after using Pi agent + Antigravity.

Yesterday, for people in oh-my-pi (OMP), Gemini via Antigravity suddenly started consistently returning 429 RESOURCE_EXHAUSTED and asking to wait 30 minutes — and this lasts for hours. This is not quota exhaustion, but an entitlement mismatch — Google is cutting the agent bucket for third-party harnesses under the guise of RESOURCE_EXHAUSTED.

OMP is a fork of Pi, and OpenClaw also uses Pi as the base for its agent runtime. So the problem potentially affects a whole branch of third-party agents.
