  • I am using the latest version of Claude Code

What's Wrong?

When I open claude code in Terminal - and the terminal is not set to full size, claude reproduces same output multiple times. This looks very buggy and also weird.

What Should Happen?

Please fix it. a CLI tool should gracefully adapt to any terminal width, not break at smaller sizes. That's a legitimate bug.

TL;DR

The issue can likely be resolved by adjusting the terminal width handling in the Claude Code application to prevent repeated output when run in a narrower terminal.

Guidance

  • Verify that the issue is specific to the terminal width by testing Claude Code in different terminal sizes to confirm the behavior.
  • Check if there are any existing configuration options or environment variables in Claude Code that can be used to control output formatting or terminal width handling.
  • Consider filing a feature request or bug report with the Claude Code developers to improve terminal width handling and prevent repeated output in narrower terminals.
  • Test the issue with different Claude models to see if the behavior is model-specific or a general issue with the application.

Example

No code snippet is provided as the issue does not imply a specific code change.

Notes

The issue may be related to the terminal width handling in the Claude Code application, but without more information or error logs, it is difficult to provide a definitive solution. The user should test the application in different environments and configurations to gather more information.

Recommendation

Apply workaround: The user can try to use a different terminal or adjust the terminal width to see if it resolves the issue, while waiting for a potential fix from the developers.
