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 disclose that no identifiers are retained, which is a useful privacy note, but it says nothing about side effects, network calls, rate limits, or what happens to the provided url, host, json, or zone inputs.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
