Notification hook receives phantom permission_prompt events with no visible permission dialog
증상
- I have searched existing issues and this hasn’t been reported yet
원인
Agent encountered an unexpected state or unhandled error condition outside the standard error handling path.
해결법
A marker-based suppression system could filter phantom permission_prompt events that follow AskUserQuestion within a short window (similar to the workaround for the Stop hook firing multiple times during git workflows - see issue #15250).
However, this workaround should not be necessary - permission_prompt events should only fire when a permission dialog is actually displayed.
