This guide will walk you through the process of customizing prompt templates in Rasa Studio. By the end, you’ll know how to view and edit assistant prompts, adjust responses to better match your assistant’s tone, and manage prompt versions — all directly from the Studio interface.

​
What Are Prompts?

Prompts are short pieces of text that guide your assistant for specific tasks. Currently in Rasa there are three different types of prompts:
  1. Rephraser Prompts: Control tone and phrasing for assistant’s using LLM-Rephraser. For the full reference Read the Reference.
  2. Enterprise Search Prompt: Specify how your assistant retrieves and presents information from knowledge sources. For the full reference read here.
  3. Command Generator Prompt (Advanced): Guide how your assistant translates user input and context into actions. For more guidance on when to customize read here. For the full reference read here.

​
Who Can Edit Prompts?

Users with the Content Editor role can edit prompts for individual messages. For editing global prompts you need the Developer role assigned. For more details on roles and how to set them up see the docs here.
