Concurrent subagent dispatch: child re-prompts on Edit / Write even when parent has explicit allow entries

Summary

When a child subagent attempts an Edit or Write on a path where the parent has explicit Edit(/path/**) and Write(/path/**) allow-entries in .claude/settings.json, the child re-prompts the user for each tool invocation as if the parent grants weren't visible.

Setup

• Parent settings.json declares both:
• Edit(/Volumes/DevSSD/repo/.claude/worktrees/**)
• Write(/Volumes/DevSSD/repo/.claude/worktrees/**)
• Parent successfully uses Edit + Write on paths matching these globs
• Parent dispatches a child subagent that also needs to Edit/Write on paths matching these globs

Expected

Child inherits the parent's Edit + Write grants and completes without re-prompting.

Actual

Child is prompted for approval on its first Edit and its first Write, regardless of the parent's declared grants.

Why we think it's not a config issue

We have explicit allow-list entries for both tool classes covering the exact paths the child needs. Adding them didn't fix the behavior. We suspect Read and Edit/Write use different code paths in the child's permission resolver, and the Edit/Write path doesn't consult the parent's allow-list.

Related

Possibly a specialization of F8 (parallel dispatch state drift). Filing separately for visibility; consolidate at triage if appropriate.

Workaround

Serial dispatch OR pre-declare every tool class in settings.json AND accept that each child re-prompts on first tool call.
