How to use it
- Use {{name}} placeholders and a JSON variables object in the second editor. Missing variables produce an error.
- Substitution is a single pass with no expression execution or recursive expansion. It is not a prompt-injection defense.
Is data sent to a model?
No. These tools run locally in your browser without calling a model API.
