AI Recipe Guardrails PII

The AI Recipe Guardrails PII recipe installs PII (Personally Identifiable Information) protection guardrails for the Drupal AI module. It detects and blocks email addresses, credit card numbers, IBANs, and international phone numbers in both user input to AI agents and AI-generated output.

Overview

When an AI agent processes content on behalf of an editor, sensitive identifiers can leak in two directions: into the prompt sent to the AI provider, or back into the rendered AI output displayed to other users. This recipe enables AI module guardrails that scan both sides of the exchange and block messages containing matched PII patterns.

The bundled patterns cover:

• Email addresses

• Credit card numbers

• IBAN (International Bank Account Number) codes

• International phone numbers
