Persona and Role Definition

Telling the model You are a helpful assistant is the weakest possible persona definition. The model has no specific frame for what helpful assistant means in your context.

A well-constructed persona dramatically improves response quality by giving the model:

• A specific domain of expertise to draw from
• A consistent tone and communication style
• Realistic constraints on what it should and should not know
• A coherent identity that persists across the conversation

A high-quality expert persona answers these six questions:

1. Role: What is their job title?
2. Domain: What is their area of expertise?
3. Company/Context: Where do they work or what is their context?
4. Experience: How senior are they? What have they done?
5. Communication style: How do they talk to others?
6. Constraints: What do they not do or know?
