Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the action ('list all connections') without revealing any behavioral traits such as pagination, rate limits, authentication requirements, or whether results are returned in a single response. This is a significant gap for a list operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
