Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description does carry some behavioral burden. 'No identifiers are retained' is a meaningful statement about data handling, and the json parameter already notes it is discarded after the check. However, the description does not disclose whether the tool makes network requests, whether it is read-only, what side effects occur, or what the response contains.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
