Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It discloses that the search matches property name, domain, range, or description, and that it operates across all ontologies. However, it does not disclose aspects like case sensitivity, wildcard support, result ordering, or any limitations, leaving room for ambiguity in behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
