Embodiments presented herein provide an editing tool for domain-specific machine-readable objects. The editing tool identifies a domain-specific machine-readable object selected for editing. The object corresponds to a page included in a sequence of pages and is configured to adjust content for the page based on variables. One or more previous pages in the sequence are configured to solicit input to define the variables. The editing tool also identifies a scenario selected for previewing the page. The scenario includes values for the variables. Assets of the object reference the variables in expressions or other logic. The editing tool renders the object based on the scenario.
