Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. The verb 'Lists' clearly indicates a read-only operation, and the description specifies the return content (answer options with vote counts). This is adequate for a simple read tool, though it does not discuss edge cases, authorization, or potential errors.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
