Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations available, the description carries the full burden for behavioral disclosure. It only states that the tool loads a file into a map, but does not mention error handling, whether the file must exist, read-only nature, or side effects. The KAGConfigEX2 semantics are referenced but not explained.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
