Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint, covering the safety profile. The description adds the 'recent' qualifier and the POST endpoint, providing some behavioral context, but does not go into depth about pagination limits or filtering nuances. This warrants a 3.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
