Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It states the tool retrieves data ('Get'), implying a read-only operation, but does not disclose behavioral traits such as authentication requirements, rate limits, error conditions, or the format/structure of the returned tree. For a tool with no annotations, this leaves significant gaps in understanding its behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
