Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already establish that this is a read-only, idempotent, non-destructive search. The description adds useful context that it searches the 2027 rankings and returns slugs, but it does not explain result ordering, limits, empty/no-match behavior, or matching semantics beyond name.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
