 on.
 
 When a DAG has known failures, it can be ommitted from Slack error reporting by adding
-an entry to the `silenced_slack_alerts` Airflow variable. This is a dictionary where the
-key is the `dag_id` of the affected DAG, and the value is the URL of a GitHub issue
-tracking the error.

-The `check_silenced_alert` DAG iterates over the entries in the `silenced_slack_alerts`
-configuration and verifies that the associated GitHub issues are still open. If an issue
-has been closed, it is assumed that the DAG should have Slack reporting reenabled, and
-an alert is sent to prompt manual update of the configuration. This prevents developers
-from forgetting to reenable Slack reporting after the issue has been resolved.
