Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. While it clearly describes the core function, it lacks behavioral details such as whether this makes an external API call, potential rate limits, privacy implications, or what format the IP address is returned in (IPv4/IPv6). The description is minimal but doesn't contradict any annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
