Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of behavioral disclosure. It clearly indicates a read operation ('Get') and mentions the authentication requirement. However, it does not detail the response format, potential rate limits, or data freshness, but given the tool's simplicity (no parameters, no side effects), this is sufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
