Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full responsibility for behavioral disclosure, but it only states the action itself. It does not mention side effects, permissions, reversibility, cascading behavior, or what the output contains. The existence of an output schema is not leveraged in the text.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
