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. The word 'Get' implies a read operation, and the phrase 'and its cards' clarifies the response scope. However, it does not mention authentication requirements, potential errors, or any additional behavioral details such as whether the response is nested or includes card fields. It is minimally adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
