 | `"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"` | Completes 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. |
