Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations are absent, so the description carries the full burden of behavioral disclosure. It does not state that the operation is read-only, describe the return format, mention required permissions, or note any rate limits or side effects. The phrase 'Get Song Details' simply restates the name without revealing observable behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
