Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries the full behavioral disclosure burden. It discloses the tool returns an overview ('概览') of P/E and P/B valuations, implying a read-only, side-effect-free snapshot, but says nothing about data recency, industry coverage, or response shape. For a zero-parameter read tool this is minimum-viable but not rich disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
