Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the transparency burden. It adds a behavioral caveat: 'Licence presence establishes snapshot presence only,' which hints at data interpretation nuances. Yet it omits auth requirements, error behavior, or return format, so transparency is incomplete.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
