Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already disclose write/non-destructive/idempotent/open-world behavior, so the safety profile is covered. The description adds that feedback is 'attributed' and 'shared with authorized participants', which usefully signals visibility and attribution, but says nothing about permissions, limits, or what a submission returns.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
