Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden and discloses important behavior: maximum 200 results, inclusion of bilingual fields/revisions, required private staff read grant plus view_association, and denial of teacher tokens. It stops short of discussing pagination or whether results are sorted, but the access and scope behavior is well covered.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
