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 explains the cause of the pause (manual or silence) and the action (resume), but it does not mention what happens if called when not paused, whether it returns any confirmation, or any side effects. This is minimal but acceptable for a simple tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
