 **Key Points**:
-- AskUserQuestion: max 4 questions/call, batch if more
+- ASK_USER: max 4 questions/call, batch if more
 - Strategy options: 2-4 strategies + "自定义修改"
 - Clarification loop via send_input: max 10 rounds, agent determines uniqueness_confirmed
 - Agent stays active throughout interaction (no close_agent until Step 3.6)
