Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover safety: readOnlyHint=true, idempotentHint=true, destructiveHint=false. The description adds the 'published' status constraint and the topic focus, which is useful context, but it does not disclose ordering, pagination behavior, or filter-combination semantics beyond what the schema already implies.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
