Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the behavioral disclosure burden. It explains that product-name queries are resolved internally, that it should not be preceded by product search, and that it is not for ranking/comparison/validation; however, it does not state read-only/no-side-effect behavior, permissions, or no-match handling.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
