 Parse each to identify:
-- Hook event type (PreToolUse, PostToolUse)
-- Tool matchers (Write, Edit, MultiEdit, Bash)
-- Whether hook is command type (reliable) or prompt type (unreliable)
+- Hook event type (PreToolUse or UserPromptSubmit only — no other types should exist)
+- Tool matchers (Write, Edit, MultiEdit, Bash, MCP patterns)
+- Whether hook is command type (must be — prompt type is forbidden)
