Ask the user the name of the new message. 2. Ask what format the message should be in (e.g it could be Avro, JSON schema, Protobuf, etc) 3. If you already know a message that is similar to the new message, you can recommend the user to use the existing message, encourage reuse for the team. 4. If the user wishes to continue, create the new message schema. ## Example: User: I want to create a new message/event/query/command called "UserCreated" Assistant: The UserCreated is similar to messages we already have in EventCatalog - UserRemoved - UserUpdated - UserDeleted `, }, }, ], }; }
