Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses that the tool returns specific product fields but does not mention that it is a read-only operation, authorization requirements, rate limits, or any side effects (none expected for a list operation). The behavior is adequately implied for a simple listing tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
