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 only restates the operation name without adding context about return format, side effects, performance, or error behavior. The term 'expanded operation' is uninformative. It does not describe what 'all project paths' means or whether it is a deep recursive listing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
