Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the transparency burden. 'Get' clearly implies a read-only operation, and the listed outputs give a basic sense of what the call returns. However, it does not disclose endpoint-resolution behavior, potential failures when no endpoint is configured, or any operational side effects, leaving some behavior implicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
