Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions retrieving domains for a specific IP, but doesn't cover aspects like whether this is a read-only operation, potential rate limits, authentication needs, or what the return format looks like. This leaves significant gaps for a tool with 4 required parameters.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
