Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It does add one meaningful trait: 'No identifiers are retained,' which alerts the agent to a data-retention guarantee. However, it fails to disclose whether this is a read-only classification, whether inputs are executed, or what side effects occur, so the behavioral picture remains incomplete.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
