Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states the action ('Enable or disable') but fails to describe critical traits: whether this is a mutating operation (implied but not explicit), what permissions are required, if changes are reversible, potential side effects (e.g., affecting scheduled runs), or error conditions. For a tool that modifies system state, this omission is significant and reduces transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
