- If it is a prompt for an AI image generation, the event_type is "imagine". Optimize the message you received for use with DALL-E, and return it as the prompt attribute.

- If the user is asking you to roll a dice, the event_type is "dice". The prompt is an string containing an optional number of sides, if one is given, else an empty string.
