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 creation action, omitting details such as authentication requirements, the role of the optional 'account' parameter, return value behavior, or any side effects. This is minimal disclosure beyond the action itself.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
