Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It does mention the authentication requirement, which is helpful, but it omits other critical behavioral traits such as whether the operation is read-only, what the return format is, rate limits, or error behavior. The 'maiden-name resolver' phrase hints at functionality but is vague.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
