Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It discloses two key behavioral traits: the operation is a soft-delete and the page can be restored later. This goes beyond a generic 'archives a page' and provides meaningful context about reversibility, though it does not elaborate on side effects or permissions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
