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 states actions ('Archive', 'prepare') but does not explain what archiving entails, whether it is reversible, what state changes occur, or any requirements (e.g., milestone must already be complete). This is insufficient for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
