Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The statement 'No identifiers are retained' provides some privacy transparency, but the description does not disclose other relevant behavior such as whether it makes network calls, has side effects, requires authentication, or how input is handled. Since no annotations exist, the description carries the full burden and falls short.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
