Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden and delivers real behavioral facts: removal is non-destructive (item stays in history, marked removed), authorization is role-gated, required items have an extra restriction, and the action is audited. It stops short of stating whether removal can be undone/re-added or what happens if the item is already removed or does not exist.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
