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 honestly discloses dynamic behavior, reliance on page hierarchy, and the constraint not to guess model names. It does not mention return format or error conditions, but for a list operation this is reasonably transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
