Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, openWorldHint and non-destructive, so the safety profile is fully covered. The description adds only a list of returned metrics, which largely duplicates the output schema rather than adding behavioral context such as coverage, survey scope, or pagination behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
