Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It clarifies that the modifier is removed without being applied (i.e., it is deleted from the stack, not applied to the geometry). This is a useful behavioral detail, but it does not disclose other important traits such as destructiveness (beyond obvious deletion), required permissions, or side effects like undo history.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
