Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description must fully disclose behavior. It merely says 'Delete a category' and omits critical behavioral details such as whether deletion is permanent, whether the 'force' parameter is required for non-empty categories, or what happens to associated posts. This leaves the agent without vital safety information.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
