Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds context about return content (full order detail with line items) but does not disclose other behaviors such as error handling, authorization needs, or rate limits. This is adequate given the annotations, but it does not go beyond them.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
