Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the behavioral disclosure burden. It states that the tool returns a WebhookInfo object with URL, pending updates count, and errors, and "Get" implies a read-only operation with no side effects. It does not detail failure modes or permission requirements, but for a zero-parameter getter this is reasonable.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
