Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate it is not read-only, not idempotent, and not destructive. The description adds nothing beyond the name, failing to disclose side effects (e.g., that it creates a persistent redirect that may affect traffic), permission requirements, or any operational nuances. With annotations already covering the basic safety profile, the description offers no additional value.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
