Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of disclosing behavior. The verb 'Get' clearly indicates a non-mutating read operation, and 'full details' suggests the response will be comprehensive. However, it does not describe error behavior, missing-task handling, or the actual response structure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
