Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, and the description reinforces a safe read operation via 'GET'. It adds useful context about the returned order contents but does not disclose other behavioral details like authorization requirements, rate limits, or error behavior. This is adequate given the annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
