Catalog or knowledge base?
This is the first decision most people face, and the two are for different jobs:- Use a catalog for structured, repeating things with attributes you would put in a table: a service and its price, a product and its stock, a plan and what it includes. The agent can look up a specific record and read a specific field (like price) from it.
- Use a knowledge base for prose the agent reads to explain things: policies, hours, how a treatment works, frequently asked questions. See Teaching your agent.
