"""
|
|
This example shows how to use output guardrails.
|
|
|
|
Output guardrails are checks that run on the final output of an agent.
|
|
They can be used to do things like:
|
|
- Check if the output contains sensitive data
|
|
- Check if the output is a valid response to the user's message
|
|
|
|
In this example, we'll use a (contrived) example where we check if the agent's response contains
|
|
a phone number.
