Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It merely states 'create a new course booking' without describing side effects, validations, permissions, error behavior, or whether the booking can fail. This adds nothing beyond the tool's name and the obvious intent of 'create'.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
