Account Suspended After Using Gemini CLI + Antigravity

[LumiDust]

Is it a request payload issue?
[ ] Yes, this is a request payload issue. I am using a client/cURL to send a request payload, but I received an unexpected error.
[x] No, it's another issue.

Describe the bug
After using this tool (Gemini CLI together with Antigravity), my account was permanently suspended. The official reason given was “logging in using third-party software.”

I want to confirm whether this tool’s login mechanism or request behavior could trigger account security detection. I did not perform any abusive or automated high-frequency requests intentionally. The suspension happened during normal usage.

I am opening this issue to understand whether:

• This tool uses unofficial authentication methods
• The login flow violates the provider’s Terms of Service
• There are known risks of account suspension when using this tool

Request Information
This is not related to a specific request payload. The issue seems to be related to the authentication or login method used by this tool.

---

Expected behavior
I expected the tool to authenticate in a compliant and officially supported way that would not result in account suspension.

If there is a risk of account bans when using this tool, it would be helpful to clearly document this warning in the README.

Additional context
If the suspension is caused by how this tool handles authentication, I believe users should be clearly informed about the potential risks.

The suspension is caused by violation of TOS of Antigravity/Gemini CLI, no matter what tool you use.

Why is the AG user still using this tool if they're going to be banned anyway? hahaha
