Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false and destructiveHint=true, so the agent knows this is an irreversible mutation. The description adds nothing on top of that: no cascade effects (e.g. does deleting an integration affect nodes?), no permission requirements, no confirmation semantics, no failure modes. No contradiction with annotations, but zero added value.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
