Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile needs no restating. The description adds that the response is pitched per audience and includes next-step routes (demo, partner interest), which is useful context, but it says nothing about localization behavior via the lang parameter or the shape of the returned content.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
