Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses the validation scope, the return shape ({ok, errors}), and the publish-gating behavior, which is solid, but it doesn't explicitly state whether the operation is read-only or if it has side effects beyond validation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
