What happened?

I am experiencing frequent ERR_STREAM_PREMATURE_CLOSE errors while using the Gemini CLI. This error has occurred multiple times
(n times) today during both long response generations and sequences of tool executions. The process terminates abruptly, forcing
me to restart the task.

What did you expect to happen?

I expected the streaming response and tool execution to complete successfully without the stream closing prematurely. The
connection should remain stable throughout long generations, or provide a more resilient recovery mechanism.

Anything else we need to know?

• Error Code: ERR_STREAM_PREMATURE_CLOSE
• Frequency: Very high (happened numerous times today).
• Context: The issue seems to trigger more often when the model is generating large amounts of text or when multiple complex
  tools are being called in succession.
• Note: I am attaching the exported chat history JSON to this issue to help with the investigation of the stream interruption.
