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 indicates a read operation ('Get') and specifies that line items and totals are included, but it does not mention side effects, error conditions, permissions, or what is returned beyond the mention. This is adequate but not rich in transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
