Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It describes what fields are included, but does not explicitly state that this is a read-only metadata lookup, nor describe return structure or side effects. This is adequate for a no-parameter field listing, but it leaves the safety profile and precise output shape implicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
