Describe the bug

I am receiving a failed request upon querying grok build 0.1 via the Supergrok integration via a X Premium+ account. It looks like the OAuth2 token was invalidated and is no longer working, this points towards a refresh failure and needs deeper investigation. It would also be great if this could be detected and the user logged out or reprompted to log back in.

To reproduce

1. Log in via XPremium+ in Warp
2. Leave integration alone for a week and use your subscription via the Grok Build CLI externally
3. Try to query grok build 0.1 in Warp

Expected behavior

The model should answer by refreshing the OAuth token or the user should be reprompted to log back in

Screenshots, videos, and logs

I'm sorry, I couldn't complete that request.

Response stream finished unexpectedly with internal error: XAI API error: POST "https://api.x.ai/v1/responses": 403 Forbidden "The OAuth2 access token could not be validated."
