Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It implies a read-only operation via the verb 'get' but does not explicitly state there are no side effects or mention any permissions or rate limits. It adds some value by listing the returned fields, but this is more output semantics than behavioral disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
