Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds context about the output (published, in GBP/EUR, per treatment/full-mouth package) but does not disclose additional behavioral traits like error conditions or data completeness. This is consistent with the moderate effort seen in similar read-only tools.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
