How to add hint if a user directly input a value for a slot?

I write a rule-based chatbot and there’s a slot named “type”, an example of it is “meeting”. What should I do if I wanna answer “this is a slot for ‘type’, plz enter ‘restart’ to create a complete application” to users directly input"meeting" in the very front of a conversation? If I add it into rules, there’ll be confliction.

@AlenChuan Hello Alen, can you give some specific bot/user conversation scenario, I not get you correctly :frowning:

how to achieve this: when the user directly input “meeting” for intent “triptype”, activate trip_form and store the value “meeting” into slot “triptype”

trip_form:
    ignored_intents:
    - chitchat
    required_slots:
      triptype:
      - type: from_entity
        entity: triptype
      - type: from_text
- intent: triptype
  examples: |
    - meeting
    - training
    - other
- rule: activate trip_form
    steps:
      - intent: bxtype-trip
      - action: trip_form
      - active_loop: trip_form
