Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the full burden of disclosing behavior. 'Short catalog' weakly implies a read-only lookup, but it does not state the output shape, whether the parameters affect the result, or why a URL, host, JSON payload, and timezone are accepted.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
