Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint and openWorldHint, so there is no safety contradiction. The description adds no behavioral context beyond that read-only fetch, such as not-found behavior, authentication scope, or whether linked data is included. It is a minimal statement of the operation rather than a disclosure of behavioral traits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
