OpenCode Desktop child-session permission prompt becomes stale after delegated sub-agent requests external_directory access #31874

Summary

OpenCode Desktop shows an external_directory permission prompt when a delegated sub-agent / child session tries to access a file outside the project directory.

However, after interacting with the permission prompt, the UI repeatedly shows:

Permission request not found:
per_eb6698362001nU7yYYtuXOycSv

The delegated task remains blocked / cannot continue.

I searched for related issues around permissions, Desktop, and subagents, but I could not find an exact match for this specific combination:

• OpenCode Desktop
• delegated sub-agent / child session
• external_directory permission request
• permission prompt shown in the parent UI
• permission request becomes stale / not found
• task remains blocked waiting for approval

Environment

• App: OpenCode Desktop
• OS: Windows
• UI language: Chinese
• Project worktree:

E:\0-CrewBeeLab\CrewBee

• External file/directory used for reproduction:

E:\0-CrewBeeLab\CrewBee-external-permission-demo\*

Steps to reproduce

1. Open OpenCode Desktop in a project worktree:

E:\0-CrewBeeLab\CrewBee

2. Create or prepare an external file outside the project worktree, for example:

E:\0-CrewBeeLab\CrewBee-external-permission-demo\demo.txt

3. From the main session, delegate a task to a sub-agent / child session.

   In my case, this happened through a CrewBee delegated sub-agent flow, where the parent session asks a sub-agent to read only this external file:

E:\0-CrewBeeLab\CrewBee-external-permission-demo\demo.txt

4. The child session triggers an external_directory permission request.

5. OpenCode Desktop displays a permission prompt in the parent UI:

需要权限
访问项目目录之外的文件

E:\0-CrewBeeLab\CrewBee-external-permission-demo\*

6. Click one of the permission buttons, such as:

• 拒绝
• 始终允许
• 允许一次

Actual behavior

After clicking the permission prompt, OpenCode Desktop repeatedly shows an error toast:

请求失败
Permission request not found:
per_eb6698362001nU7yYYtuXOycSv

The delegated sub-agent task does not continue and appears to remain blocked waiting for the permission response.

Expected behavior

The permission response should be routed back to the correct child-session permission request.

After clicking:

• Allow once: the child session should continue once.
• Allow always: the child session should continue and persist the rule.
• Deny: the child session should receive a denial and return a clear blocker.

The UI should not keep a stale permission prompt or repeatedly show Permission request not found.

Notes / suspected area

This looks related to permission prompt routing for child sessions / subagents in OpenCode Desktop.

The request itself appears to be created and surfaced to the parent UI correctly, because the external_directory prompt is visible.

The problem seems to happen when replying to the prompt: the UI attempts to respond to a permission request id that is no longer found or not associated with the route used by the visible prompt.

Potentially related areas:

• child session / subagent permission request routing
• parent session request tree aggregation
• Desktop/Web permission prompt state
• stale permission prompt cleanup
• permission response endpoint using the wrong session/request context

This does not look like a permission rules engine issue alone, because the external_directory request is displayed correctly.
