 ### Prompt Engineering
-1.  **Format Outputs**: If you need JSON for a downstream node, ask for it explicitly in the prompt: "Return only valid JSON with fields 'risk' and 'reason'."
+1.  **Use Structured Output**: When you need consistent JSON for downstream nodes, enable **Structured Output** instead of relying on prompt instructions. This guarantees schema compliance and eliminates parsing errors.
 2.  **Use System Prompts**: Set high-level rules (e.g., "You are a senior security researcher") in the System Prompt parameter instead of the User Input.
 3.  **Variable Injection**: Use `{{variableName}}` syntax to inject data from upstream nodes into your prompts.
