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 it retrieves a list of orders for an account but doesn't describe what the list includes (e.g., all orders, filtered by status), how it's paginated, any rate limits, authentication needs, or the return format. This leaves significant gaps for a tool that likely interacts with financial data.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
