Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, which are consistent with a search tool. Description adds value specifying searchable fields and pagination, but does not disclose behavior beyond what annotations already imply.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
