Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=true, so the agent knows this is a safe public read. The description adds the 'public' qualifier and slug provenance, but discloses no pagination, rate-limit, or freshness behavior, which is a modest gap for a live-data tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
