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 general action and does not reveal important traits such as the output format (e.g., multiple-choice questions), whether it invokes an external pattern, any limitations on input size, or how the questions are generated. This lack of transparency could leave an agent uncertain about side effects and expected results.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
