Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must disclose all behaviors, but it only states 'List all available work package priorities.' It lacks details such as whether the list is paginated, sorted, or includes any filtering. The minimal description does not fully inform the agent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
