Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds useful contextual detail about what the newsroom contains, such as citations, correction metadata, publication gates, and evidence limits, but it does not explain behaviors like ordering, pagination, or what 'publication gates' mean in practice.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
