Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of disclosing behavior. It adds a key behavioral consequence: the webhook will stop sending events immediately. However, it does not mention irreversibility or other side effects, but the immediate-stop detail provides meaningful transparency beyond the basic delete action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
