What to get right before you build an AI agent

Work through this before anyone writes a prompt. The model is the part of this project least likely to be your problem.

  1. 01

    Name the one job it does.

    An agent that "helps customers" cannot be built or tested. An agent that "answers where-is-my-order and reschedules deliveries" can be. Scope is the single biggest predictor of whether an agent reaches production.

  2. 02

    Decide what it is allowed to do, not just what it can say.

    Reading an order is one risk profile. Issuing a refund is another. Write the list of actions before anything is built, because that list is the security boundary and it is much harder to narrow later.

  3. 03

    Find the source of truth for every fact it will state.
