Define the purpose
The purpose is the single most important field on an AI Fellow. It's the plain-language brief that tells the Fellow who it is, what it should do, how it should sound, and what it must not do. Every conversation gets shaped by this text.

What a good purpose looks like
A useful purpose covers four things:
- Role. What the Fellow is in the conversation. A coach, a customer, an interviewer, a support agent.
- Tone. How it should speak. Formal, friendly, blunt, warm.
- Scope. What topics it should engage with. Just as importantly, what it should not go into.
- Context. Anything the Fellow needs to know about the user it's talking to or the situation.
Example. "You're a sales coach specializing in B2B SaaS. Your role is to simulate sales meetings with prospective clients. Play a skeptical IT director who needs convincing on ROI before approving a purchase. Push back on integration, security, and total cost of ownership. Evaluate whether the user handles objections professionally."
The purpose is written once and applies to every conversation the Fellow has. If you need different behaviour for different audiences, build a separate Fellow for each. There's no cap on how many you can have.
