Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=true, so the safety profile is covered structurally. The description adds nothing beyond that: no information about pagination behavior, ordering, retention window, or what entries contain. For a log-reading tool with an open-world hint, the description contributes essentially no behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
