Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, openWorldHint=false, and destructiveHint=false, covering the safety profile. The description adds no behavioral context beyond what annotations provide — no mention of return shape, pagination behavior, or scope of results. Since annotations carry the burden and the description contributes nothing extra, this scores low.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
