Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
While annotations correctly mark the tool as readOnlyHint=true and destructiveHint=false, the description adds no additional behavioral context, such as output format, pagination behavior, or permission requirements. Reliance on annotations alone is acceptable but the description misses an opportunity to enrich transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
