Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden and does not meet it. It does not state whether the deletion is reversible, whether it is actually a simulation, whether the confirm parameter gates real destruction, or what token auth is required. The "(dry-run)" hint gestures at safety but is too ambiguous to rely on.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
