Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must convey behavioral traits. It merely states 'Enable' which implies a state change, but it does not describe any side effects, required permissions, or what happens after enabling. The lack of detail leaves the agent uncertain about the tool's impact.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
