# Transforms

> Template-driven data shaping with Handlebars / Liquid

The `transform` node runs a Handlebars / Liquid-style template against the context. Outputs land in `nodes.<id>.output` or, with `output_to: state.<name>`, in workflow state.

```yaml theme={"system"}
type: transform
config:
  template: |
    {
      "patient_summary": "{{input.patient.name}} — PHQ-9 score: {{state.phq9_score}}",
      "high_risk": {{ gt state.phq9_score 14 }}
    }
  output_to: state.summary

```

Transforms are sandboxed: no I/O, no network, no PHI exfiltration paths.
