Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden for behavioral disclosure. It does add context about forwarding X-WR-API-Key/Bearer auth when present, which is useful. Yet it omits other important behaviors such as whether the operation is read-only, how invalid addresses are handled, or any rate limits, leaving significant gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
