Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations present, the description carries the full burden of disclosing behavioral traits. The two-word description provides no information about side effects, authorization needs, rate limits, or what happens when a task is added. It does not contradict annotations because there are none, but it is completely uninformative.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
