Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden. It implies removal but never states that deletion is permanent/irreversible, whether it needs confirmation, or what happens when the UUID does not exist. Only the 'one item' scoping is disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
