Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description reveals that validation relies on external published data from seoapi.com, which implies a dependency on external sources. However, it does not disclose behavioral traits like rate limits, response time, or what happens if the IP is invalid. Without annotations, more detail would be beneficial.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
