Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description goes well beyond the openWorldHint annotation by revealing the human-mediated DNS process, propagation timing, and the platform's independent re-checking. However, it contains a factual contradiction: it claims the platform reduces a full URL like `https://shop.example.com/page` to `shop.example.com`, while the schema explicitly states a scheme will result in a 422 error. This inconsistency undermines the transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
