Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is fully specified. The description adds that it returns rewards season, standings, and owner score, but does not disclose behaviors like pagination or how the limit parameter affects results. Since annotations cover safety, the description's limited additional context earns a middle score.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
