Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is fully covered. The description adds the source registry (RIPE NCC) and open-world hint is also annotated. However it does not say what fields 'network information' returns (ASN, netblock, org, abuse contact), leaving the payload opaque.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
