Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It implies a read operation ('Get') but doesn't specify details like data recency, pagination, rate limits, or authentication needs. This leaves significant gaps in understanding how the tool behaves beyond basic retrieval.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
