Overview

The Extract Dynamic Variables tool lets your agent capture specific pieces of information a caller provides — like their name, phone number, or appointment preference — and store them as variables that can be referenced throughout the rest of the call.

​
Setup

1

Add the tool

In your agent’s Functions section, select Extract Dynamic Variable from the dropdown.
2

Define each variable

For each variable you want to capture, provide:

DescriptionWhat this value represents
Data typeOne of: Text, Number, Enum, Boolean
Enum optionsRequired if type is Enum (e.g. "Yes", "No", "Maybe")
3

Update your prompt

Tell the agent when to extract the information:
When the user states their name and phone number, extract the information by calling the extract_user_details function.
