To activate this recipe you must create a new recipe which fills in the required parameters. In your rewrite.yml create a new recipe with a unique name.

rewrite.yml
---
type: specs.openrewrite.org/v1beta/recipe
name: com.yourorg.SecureTempFileCreationExample
displayName: Use secure temporary file creation example
recipeList:
- org.openrewrite.java.security.SecureTempFileCreation:
target: All Source
