Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure, but it only offers a heading-like phrase. It does not state whether the operation is read-only, what data is returned, whether a running simulation is required, or any side effects, offering essentially no behavioral transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
