Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full disclosure burden for a destructive operation, and it fails to meet it. It never states whether deletion is permanent or reversible, whether it cascades to subtasks/comments, what permissions are required, or how failures manifest. Only the verb "delete" hints at a write/mutation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
