Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It mentions the return type (JSON string) but does not explicitly confirm this is a read-only operation, note any permission requirements, or indicate potential side effects or performance considerations. The verb 'Get' implies read-only but lacks explicit assurance.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
