Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It implies a read-only operation via '读取' but does not explicitly declare non-destructiveness. It does note that permission approvals cannot be handled here, which is a useful limitation. However, it omits any description of return format, pagination, or side effects, leaving the agent partially in the dark.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
