# tool si.act.notification_rule

Writes one notification rule, which says who is told and never what happens: The answer gives the rule, with the next notice it will send.

[figure: Over MCP, si.act.notification_rule takes NotificationRuleInput and returns a card whose body is NotificationRule.]

The answer gives the rule, with the next notice it will send. The call needs the act grant at the user rung.
