Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, openWorld, and idempotent hints, and the description adds context beyond them: no API key required, case-insensitive filtering, and the return of both open jobs and a skill-matched subset. This aligns with the annotations and adds useful behavioral detail without contradicting them.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
