Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must bear the burden of behavioral disclosure. It indicates a read operation ('获取') and explains the return content, but does not explicitly state side effects (or lack thereof), permissions, or edge cases. The main behavior is clear but not deeply transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
