Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare this a safe, idempotent, non-destructive closed-world read, so the description's main added value is enumerating return fields (name, price, stock status, product type), which matters because there is no output schema. It does not mention that results are capped by page size or whether the list is ordered in any way.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
