Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. 'Check the status' implies a read-only operation, but the description does not disclose the response format, authentication requirements, or potential edge cases like invalid domains. The behavioral traits are left largely implicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
