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 fails completely. It doesn't indicate whether this is a mutating operation, what permissions are required, what happens on success/failure, or any side effects (e.g., notifications sent). The single verb 'Create' implies mutation but offers no behavioral details.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
