claude-code - 💡(How to fix) Fix Concurrent subagent dispatch: child re-prompts on Edit / Write even when parent has explicit allow entries

TL;DR

The child subagent may not be properly inheriting the parent's Edit and Write grants due to a potential issue with the permission resolver, and a workaround involves serial dispatch or pre-declaring every tool class in settings.json.

Guidance

• Verify that the parent's settings.json file is correctly formatted and that the globs for Edit and Write are correctly specified.
• Check if the child subagent is correctly configured to inherit the parent's grants, and if there are any other settings or configurations that may be overriding this behavior.
• Consider implementing the suggested workaround of serial dispatch or pre-declaring every tool class in settings.json to see if it resolves the issue.
• Review the related issue F8 (parallel dispatch state drift) to see if it may be relevant to this problem.

Example

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

Notes

The issue may be related to a specialization of F8, and consolidating the issues at triage may be necessary. The workaround provided may have limitations, such as requiring each child to re-prompt on the first tool call.

Recommendation

Apply the workaround of serial dispatch or pre-declaring every tool class in settings.json, as it may help mitigate the issue while a more permanent solution is developed. This is because the workaround has been suggested by the issue reporter and may provide a temporary fix until the underlying issue is resolved.
