Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=true and openWorldHint=true, so the safety profile is already covered. The description adds nothing on top of that — no note about scoping, permissions, or what a retrieved product set represents, so it contributes essentially zero behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
