Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already mark the tool as read-only, non-destructive, and open-world. The description adds value by specifying inputs (parameter mentions in schema but not description), outputs (normalized rows with budget, skills, client signals), and data freshness (live, ingested by JobsPipe). The description does not contradict annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
