Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full behavioral burden. It does add useful scope context by specifying "recebidas" (received) rather than written, but it discloses nothing about ordering, pagination, visibility/privacy filtering, or authentication needs for a read-only listing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
