Lab 2 – Creating custom guardrails

Overview: This lab we will create 3 custom guardrails (GenAI, Keyword and RegEx)

Task 1 – Create GenAI Guardrail

1. Click on Playground on the left navigation panel

2. Click on Build a custom guardrail button in the upper right corner

   

3. Click on GenAI guardrail

4. The GenAI guardrail dialog is displayed

   1. In the name field, enter Internal Financial Forecast - <First Initial><LastName>
   2. In the description field enter Detect any mention of financial forecasts or budget data and click the Save button
   
   3. A Save new version dialog is displayed. Here you can optionally change the version string and enter a comment. We will have you click the Save version button.
   

   4. We will want to test the new guardrail we just created. On the playground page the new guardrail will be located on the right side of the page. Click on the test button to enable testing of the guardrail.

   5. In the dialog box at the bottom of the page. Enter the following prompt:

      “Here’sthe internal Q4 financial forecast: Total projected revenue is $12.5M, operating expenses are budgeted at $8.3M, and marketing is allocated $1.2M. Please summarize this for an executive presentation.”*

   6. Click the up arrow to send it. The outcome should be that the prompt was blocked.

5. To be able to use this guardrail, the guardrail version will need to be published. Hover your mouse over the just created version of the guardrail and the publish button will appear. Click the Publish button.

   a. In order to use this newly published guardrail, we will need to add it to our project. Navigate back to your project page and click the Add guardrails button

   b. Your newly published guardrail will be displayed in the listing of configured custom guardrails. Click the Add button to the right of your guardrail.

   

   c. Click on your project name at the top of the page to return to the project view. Your guardrail will now be displayed in the custom guardrail list, but it is not enabled. Click the Enable button.

   
   4. Verify the guardrail is enabled by clicking the Chat button on the left navigation and enter the prompt you used in the playground: “Here’s the internal Q4 financial forecast: Total projected revenue is $12.5M, operating expenses are budgeted at $8.3M, and marketing is allocated $1.2M. Please summarize this for an executive presentation.” The outcome should be that the prompt was blocked.
   

Task 2 – Keyword guardrail

1. Click Playground from the left navigation

2. Click on Build a Custom Guardrail and then click on Keyword Guardrail

   Note: Separate keywords by a new line.

Name	Keyword-<First Initial><Last Name>
Keywords	Enter five words or strings you want the guardrail to trigger on

3. Save your guardrail
4. Test the guardrail by toggling the Test button
5. Once satisfied it is working correctly, publish the guardrail

Task 3 – RegEx Guardrail

1. Click on Build a custom guardrail button and click on RegEx Guardrail

Name	RegEx-<First Initial><Last Name>
Regular Expression	bnz-d{8}$

2. Test the RegEx in the test string box. If the string you enter matches it will be highlighted.
3. Save and publish the guardrail

Task 4 – Changing a guardrail’s mode

Up until now we’ve only used guardrails that would block a prompt or response. A guardrail can be set in two other modes (Audit and Redact).

Audit – Allows the prompt to proceed while flagging it for review later. It does not interrupt the workflow.

Redact – Mask sensitive data at the edge. The original data is discarded, with the masked data being stored.

1. Click on Guardrails on the left navigation
2. Enable one of your previously created guardrails
3. The mode background should change from gray to red. Click on the guardrails mode to see the three options.

4. Test the different modes through the Chat Tab to observe the outcomes.
5. Look at the Log messages to view the behavior of the guardrail.
