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. It simply restates the tool's name ('Returns list of issue resolutions') and provides no information about data scope, ordering, permissions, or response format, adding no value beyond the name.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
