FAQ

What prompt formats are supported?

We support Mustache-style {{variable}}, Jinja2, f-string, and custom delimiters. The editor auto-detects your format.

How does the API integration work?

Send a POST request with your template and variable payload. Get back a structured validation report in milliseconds — before any LLM call is made.

Can I use this in my CI/CD pipeline?

Yes. The REST API and Node.js SDK are designed for automated pipelines. Fail builds early when prompt templates are misconfigured.
