Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden for behavioral transparency. It states it gets a campaign (read operation) but does not disclose any permissions, rate limits, or side effects. For a simple GET, the behavior is assumed, but the description adds no extra context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
