What happened?

gemini-3.1-pro-preview can get stuck while thinking, trying to call a tool, but not doing it for a very long time, ending up saying the same stuff over and over. <img width="1426" height="458" alt="Image" src="https://github.com/user-attachments/assets/e78fa22e-196f-4bea-9dd9-7e3177cc6939" />

What did you expect to happen?

It should call the right tool immediately

TL;DR

The issue might be resolved by investigating the tool invocation process in the gemini-3.1-pro-preview model to ensure it's correctly configured and not causing the stuck state.

Guidance

  • Verify the tool invocation configuration in the gemini-3.1-pro-preview model to ensure it's set up correctly.
  • Check for any known issues or updates related to the gemini-3.1-pro-preview model that might be causing the problem.
  • Run the /about command in the Gemini CLI to gather more information about the environment and configuration.
  • Investigate the possibility of a timeout or retry mechanism in the tool invocation process that might be causing the repetitive behavior.

Example

No code snippet is provided as the issue does not contain sufficient technical details to create a relevant example.

Notes

The provided information is limited, and the root cause of the issue is unclear. Further investigation into the gemini-3.1-pro-preview model and its configuration is necessary to determine the exact cause and solution.

Recommendation

Apply workaround: Investigate and adjust the tool invocation configuration and process to prevent the stuck state, as the issue seems to be related to the specific model and its interaction with tools.
