Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already establish readOnly, idempotent, and non-destructive behavior. The description adds meaningful behavioral detail beyond annotations, such as public-read behavior, key-gated mine/status filtering, and the note that proposals are sealed and anonymized tapes publish after close. No contradiction with annotations exists.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
