Access variables using curly braces and the props object. Set test values for your variables in the test_settings:
Test settings are only run automatically in the VSCode extension, or AgentMark Cloud.
math-tutor.prompt.mdx
---
name: math-tutor
text_config:
  model_name: gpt-4
test_settings:
  props:
    difficulty: "beginner"
    showSteps: true
---

<System>
You are a math tutor.
<If condition={props.showSteps}>
  Always show detailed steps in your explanations.
</If>
Explain at a {props.difficulty} level.
</System>

​
Complex Objects

You can use nested objects and arrays:
user-profile.prompt.mdx
---
name: user-profile
text_config:
  model_name: gpt-4
test_settings:
  props:
    user:
      name: Alice
      preferences:
        language: Spanish
        topics:
          - math
          - science
---

<System>
Respond to {props.user.name} in {props.user.preferences.language} about {props.user.preferences.topics[0]}.
</System>

Best Practices

  1. Use descriptive variable names
  2. Set test props in test_settings
  3. Keep object structures simple and flat when possible
  4. Test with different variable values
