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 the core function but omits details like time source (system clock or service), return format (ISO 8601? timestamp?), or potential delays. However, an output schema exists (not shown here but indicated), which likely documents the return structure. The description is minimally adequate for a simple read-only tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
