What happened?

Started in plan mode, set model 3.1 pro preview. attempted to create a plan to build out a folder structure and rudimentary markdown files for a workout routine. Gemini thought for 2 full minutes before I stopped it. It did not present me back a plan to implement. It's unclear why using plan mode is hanging up the responses back.

[ACTION REQUIRED] 📎 PLEASE ATTACH THE EXPORTED CHAT HISTORY JSON FILE TO THIS ISSUE IF YOU FEEL COMFORTABLE SHARING IT.

I've removed the folder structure from the bug chat report history for privacy. bug-report-history-1775838417828.json

What did you expect to happen?

I started with the prompt: create a new folder in my areas folder. i want to build out a fitness and strength and conditioning workout routine. build out a user profile for me. i have right elbow tendonitis which flares under heavy use. i play basketball every saturday morning and wear a compression sleeve. there are certain tricep exercises that i have difficulty completing. i want to document these specific exercises so we can find better less strenuous alternatives.

I would expect that Gemini provides an implementation plan back. Even if the task seems simple, I want to confirm how it gets implemented and tweak it before we move if possible.

TL;DR

The issue can be resolved by investigating the exported chat history JSON file to identify potential causes of the hang-up in plan mode.

Guidance

  • Review the attached chat history JSON file to understand the conversation flow and identify any potential errors or inconsistencies that may have caused the hang-up.
  • Verify that the model version (gemini-3.1-pro-preview) is compatible with the CLI version (0.37.0) and check for any known issues or updates related to plan mode.
  • Test the plan mode with a simpler prompt to determine if the issue is specific to the provided prompt or a more general problem.
  • Check the memory usage (277.3 MB) to ensure it's not causing performance issues, although it doesn't seem excessively high.

Notes

The provided information is limited, and without further details or access to the chat history JSON file, it's challenging to provide a more specific solution. The issue may be related to the model version, prompt complexity, or other factors not immediately apparent from the provided information.

Recommendation

Apply workaround: Investigate the chat history and simplify the prompt to identify potential causes and mitigate the issue, as the root cause is unclear and may require further troubleshooting.
