Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must fully convey behavioral traits. It only states the basic function—getting details—but omits important information such as whether the operation is read-only, required permissions, error handling for invalid route_id, or what 'detailed information' entails. The description is insufficient for an agent to understand side effects or constraints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
