Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, placing the full burden on the description. The description only states 'Enable/disable a webhook' without clarifying whether it toggles the current state or sets it to a specific value, or any potential side effects. The existence of an output schema is not leveraged to mention return behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
