Frequently Asked Questions

How are variables written?

Place a variable name inside double curly braces, such as {{audience}} or {{output_format}}. The studio creates an input for every unique variable.

What does the export contain?

The JSON package contains the original template, current variable values, and rendered prompt for portable storage or versioning.

Can this reveal missing variables?

Yes. Unset placeholders remain visible in the rendered prompt and are listed as missing.
