Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits itself, but it only states that a ticket is created and that a string is returned. It does not mention side effects, persistence, permissions, or any follow-up actions, which matters for a mutating create operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
