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 HTTP method and basic action, offering no information about pagination behavior, return shape, ordering, or whether the response contains sensitive webhook data. This is minimal and under-disclosing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
