Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It conveys a destructive POST mutation and the required payload, but does not disclose whether deletion is permanent or recoverable, what side effects occur (e.g., whether it feeds the delete history that get_delete_history reads), what authorization is needed beyond supplying a userId, or the response shape. For a mutation, this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
