Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It reveals the internal two-step process (lookup members then filter tasks), which is helpful. However, it does not mention other important behaviors such as authentication requirements, error handling, or what happens if the member is not found.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
