Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint and destructiveHint false, so the description's claim 'Search candidates' aligns. However, the description adds no additional behavioral context such as pagination behavior, rate limits, or permission requirements beyond what the schema provides.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
