TL;DR

The Gemini CLI may be overwriting the whole file due to a configuration or usage issue, and checking the documentation or seeking support for the correct edit command is necessary.

Guidance

  • Review the Gemini CLI documentation to ensure the correct usage of the edit command, as the current behavior suggests it may be overwriting the file intentionally or due to a misconfiguration.
  • Verify the command being used to edit the file, as the issue implies that the command is set to overwrite the file instead of making targeted changes.
  • Check for any configuration options or flags that can be used with the edit command to prevent overwriting the entire file.
  • If the issue persists, consider seeking support from the Gemini CLI community or developers to clarify the intended behavior and usage of the edit command.

Notes

The provided information does not include the specific command being used to edit the file, which makes it difficult to provide a precise solution. The Gemini CLI version and configuration may also impact the behavior, so ensuring the latest version is being used and reviewing the configuration settings is recommended.

Recommendation

Apply workaround: The user should review the documentation and seek support to understand the correct usage and configuration of the Gemini CLI edit command to prevent overwriting the entire file.
