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 but offers no information about the tool's effects. It doesn't indicate whether this is a mutating operation, what permissions are required, potential side effects, or response format, making it impossible for an agent to assess risks or outcomes.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
