Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of disclosing behavior. 'Print' indicates a read-like operation, but it does not explicitly state that there are no side effects, nor does it describe what the catalogue contains. It is adequate but lacks depth, relying on the output schema for return details.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
