Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It states the action is 'Delete' which implies a destructive, irreversible operation, but doesn't specify permission requirements, whether it's synchronous/asynchronous, what happens to user data, or error conditions. The mention of 'Returns: Status message' is minimal behavioral information.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
