TL;DR

Investigate the nah_guard configuration and its interaction with Claude to resolve the permission issues.

Guidance

• Review the nah_guard documentation to understand its default behavior and how it might be interfering with Claude's permission prompts.
• Check the system logs for any errors or warnings related to nah_guard or Claude to identify potential issues.
• Verify that the nah_guard version is compatible with the current Claude version (2.1.119) to rule out version conflicts.
• Consider temporarily disabling nah_guard to see if it resolves the permission issues with Claude.

Example

No code example is provided due to the lack of specific implementation details in the issue.

Notes

The issue description suggests that nah_guard might be the cause of the permission problems, but without more information about the configuration or implementation, it's difficult to provide a more specific solution.

Recommendation

Apply a workaround by temporarily disabling nah_guard to determine if it's the root cause of the permission issues, as this will help isolate the problem and potentially lead to a more permanent solution.
