Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states only that it gets mappings, without indicating that it is a read-only operation, any authentication requirements, rate limits, or potential side effects. For a tool with no annotations, this is minimal disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
