Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It does disclose a meaningful behavioral trait—'No identifiers are retained'—and 'Show' weakly implies a read-only operation. However, it does not state whether any data is stored, what output the classification produces, or whether there are side effects, leaving significant behavioral ambiguity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
