Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=false, which accurately characterize this as a safe, read-only operation. The description adds useful context that the profile is 'public' (no auth barrier beyond the api key), and specifies the input constraint. No contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
