Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of conveying behavior. 'Get' clearly indicates a read-only operation with no destructive side effects, and the tool's simple nature needs little additional behavioral disclosure. It does not mention rate limits or error conditions, but for a straightforward lookup these are not critical gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
