TL;DR

The issue may be resolved by setting the CLAUDE_CODE_EFFORT_LEVEL environment variable to force the effort level setting to propagate to subagents or team agents.

Guidance

• Check if the effortLevel setting in settings.json is correctly formatted and valid.
• Verify that the CLAUDE_CODE_EFFORT_LEVEL environment variable is not set, as its absence might be causing the issue.
• Investigate the error messages to determine if the issue is related to lock acquisition or request failures.
• Review the documentation to ensure that the effortLevel setting is supported in the current version (2.1.119) and platform (darwin).

Example

No code snippet is provided as it is not clearly supported by the issue.

Notes

The issue might be specific to the darwin platform or version 2.1.119, and further investigation is needed to determine the root cause.

Recommendation

Apply workaround: Set the CLAUDE_CODE_EFFORT_LEVEL environment variable to force the effort level setting to propagate to subagents or team agents, as its absence is likely causing the issue.
