Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already signal readOnlyHint=true and openWorldHint=true, covering the safety profile. The description adds that the response includes the employer block and bid count, which is mild behavioral context, but it does not disclose response shape, pagination (likely irrelevant for single-item), error conditions, or auth requirements. With annotations present, the description adds only a modest amount beyond them.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
