Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It indicates a read operation via 'Get', which implies non-destructiveness, but no additional behaviors (e.g., rate limits, authentication needs) are disclosed. The simplicity of a no-parameter retrieval partially mitigates this gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
