Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full behavioral burden. It discloses that only the caller's jobs are returned and that counts are included, but it does not describe ordering, read-only status, pagination behavior, or what the counts represent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
