AI Agent Builder can only generate the functional configuration of the AI Agent Step. It does not help generator the AI Persona, which can be customised manually after applying the configuration for AI Agent step.

Allow AI Agent Builder to also ask for the desired AI Persona. Then, once the user is satisfied with the generated AI Persona, the user can confirm with the AI Agent Builder and apply the AI Persona on the AI Agent Step so as to configure a well written persona that the AI Agent Step can follow.
