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 return format (JSON string) and error handling (Chinese error messages), which is helpful. However, it doesn't mention pagination behavior beyond parameter defaults, rate limits, authentication needs, or whether this is a read-only operation. The description adds some context but leaves gaps for a tool with 11 parameters.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
