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 explains the composite signal construction, score levels (Critical, Elevated, Moderate, Low), and the authentication requirement. It doesn't mention rate limits or error behavior, but the core behavior and prerequisites are transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
