Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It discloses that the response includes transaction accounts and scenarios, but does not state whether the operation is read-only, error behavior, or authorization requirements. For a simple get-by-ID, this is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
