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 usefully discloses that the tool does not contact Audacity, implying a read-only, local operation. However, it does not say what kind of runtime/server details are returned, whether any errors are possible, or how the information is structured, leaving some ambiguity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
