Hook events must be valid event names

Warning

Rule Details ​

This rule validates that the keys in the hooks object of settings.json correspond to recognized Claude Code hook events. Valid events are: PreToolUse, PostToolUse, PostToolUseFailure, PermissionRequest, UserPromptSubmit, Notification, Stop, SubagentStart, SubagentStop, PreCompact, SessionStart, SessionEnd, TeammateIdle, and TaskCompleted. An unrecognized event name means the hook will never fire, silently failing to provide the intended automation.
