Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description 'Show company profile' is consistent with the annotations (readOnlyHint=true, destructiveHint=false), but it adds no extra behavioral context such as expected return format, pagination, or auth requirements. With annotations already covering the safety profile, the description contributes nothing beyond what is already declared.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
