Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the safety burden and discharges it well by flagging the operation as IRREVERSIBLE and advising a checkpoint. It also notes ordering behavior. It does not spell out that baked modifiers are removed from the stack, but the warning is sufficient context for a destructive operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
