Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden for behavioral disclosure, but it only states the tool gets actual effort details. It does not mention any filtering behavior (e.g., by work item id), permissions, pagination, or return format, leaving significant behavioral ambiguities for a list operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
