Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of behavioral disclosure. It discloses the output format and the fact that tenant/version/id are excluded, implying a portable export. However, it doesn't explicitly state that the operation is read-only or has no side effects on the original storyline.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
