AgentMark provides a set of built-in filters that you can use to manipulate and transform data within your prompts. Filters are functions that take an input value and return a transformed output.

​
Basic Usage

Use filters by calling them on values in your prompts: 
---
name: greeting
metadata:
  model:
    name: gpt-4
test_settings:
  props:
    userName: "alice"
    items: ["apple", "banana", "cherry"]
---

<System>
Your name is {capitalize(props.userName)}!
Your items are: {join(props.items, ", ")}
</System>
<User>
What is your name, and what items do you have?
</User>
