Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations present, the description carries the full burden of behavioral disclosure. It reveals a privacy-relevant behavior (identifiers are not retained) but remains silent on what 'classified' means, how the four parameters (url, host, json, zone) are consumed, and what the tool returns. This is a meaningful gap for a tool that appears to perform some kind of request analysis.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
