 Flow Directives are commands within a workflow that dictate its progression.

+| Directive | Description |
+| --------- | ----------- |
 | `"continue"` | Instructs the workflow to proceed with the next task in line. This action may conclude the execution of a particular workflow or branch if there are not task defined after the continue one. |
-| `"exit"` | Complete the current scope's execution, potentially terminating the entire workflow if the current task resides within the main `do` scope.                                                   |
-| `"end"` | Provides a graceful conclusion to the workflow execution, signaling its completion explicitly.                                                                                                |
