No. RM is not a programming language. It doesn't have lines of code. It creates a UI summary of the actions that are setup to show what those actions are, but that is not "code" in any way.
If you want to include text in actions, either use the Log action, or as suggested above, use a virtual notification device. Or, better than that, use the Notes section of the rule to write down whatever you want. For example, you could copy the UI summary of the actions and paste into the Notes section, and add any comments you want there.
Keep your automations simple.
