Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the behavioral burden. It usefully discloses that the record includes gaps and that silence should not be interpreted without consulting it. However, it does not explicitly state read-only semantics, return format, or other operational behavior, though the get_ name implies a safe retrieval operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
