You can extend these rules by adding an appropriate action (for example, send an email or create an issue) to be triggered when the rule conditions are met. These actions are defined within each rule and implemented by the appropriate connector for that action e.g. Slack, Jira. You can create any rules from scratch using the **Manage Rules** page, or you can create specific rule types from their respective UIs and benefit from some of the details being pre-filled (for example, Name and Tags).
