Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, idempotent, openWorld, and non-destructive behavior, so the description's main job is to add request-specific context. It adds 'one' and 'unsigned request ID' but does not describe return value, not-found behavior, or how the ID relates to other tools. 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.
