claude-code - 💡(How to fix) Fix CLAUDE_CODE_SUBPROCESS_ENV_SCRUB should not override permission mode

TL;DR

Decoupling the CLAUDE_CODE_SUBPROCESS_ENV_SCRUB environment variable from the permission mode selection is likely to resolve the issue.

Guidance

• Review the current implementation to identify where the coupling between CLAUDE_CODE_SUBPROCESS_ENV_SCRUB and permission mode selection is occurring.
• Modify the code to ensure that CLAUDE_CODE_SUBPROCESS_ENV_SCRUB only controls environment variable sanitization, without affecting the permission model.
• Introduce a separate mechanism to control the permission model independently, allowing users to opt into env scrubbing without losing control over their permission settings.
• Verify the changes by testing the --dangerously-skip-permissions flag with CLAUDE_CODE_SUBPROCESS_ENV_SCRUB set, to ensure the permission mode is not forced to default.

Example

No code snippet is provided as the issue does not contain sufficient implementation details.

Notes

The suggested fix assumes that the current implementation can be modified to decouple the two behaviors. If the issue is due to a third-party library or external dependency, additional steps may be required to resolve the issue.

Recommendation

Apply a workaround by setting CLAUDE_CODE_SUBPROCESS_ENV_SCRUB=0 to opt out of env scrubbing, allowing for independent control over the permission model, until a permanent fix is implemented.
