Varbase AI Safety

A recipe to bundle a complete AI safety stack for Varbase — guardrails, logging, and observability.

This recipe provides a defense-in-depth AI safety setup including:

• Drupal AI module (ai)
• AI Logging (ai_logging) with 90-day retention enabled by default
• AI Observability (ai_observability) for transparency and compliance reporting
• 14 guardrail rules across 3 sets, configured against restrict_to_topic and regexp_guardrail plugins

Sub-Recipes Applied

This recipe chains the following upstream recipes via the recipes: key:

• drupal/ai_recipe_guardrails_prompt_safety — Prompt Safety: Liability set + Prompt Safety: Security set
• drupal/ai_recipe_guardrails_pii — PII Protection set

Included Guardrail Sets

Prompt Safety: Liability (prompt_safety_liability)

Blocks topics that carry legal or reputational risk for the site owner.

• Liability: Legal Advice
• Liability: Medical Advice
• Liability: Sensitive Topics

Prompt Safety: Security (prompt_safety_security)

Blocks structurally malicious input and semantic prompt attacks (XSS, HTML/CSS/JavaScript injection, prompt manipulation/jailbreak detection).

• Security: CSS Expression Injection
• Security: Dangerous HTML Tags
• Security: HTML Event Handler Injection
• Security: JavaScript Execution Functions
• Security: JavaScript Protocol
• Security: Prompt Manipulation
• Security: Script Tag Injection

PII Protection (pii_protection)

Detects and blocks personally identifiable information (PII) in both user input and AI output. Baseline GDPR / data-protection coverage.

• PII: Credit Card Number
• PII: Email Address
• PII: IBAN
• PII: Phone Number

AI Logging Settings Applied

• prompt_logging: true (automatic logging enabled)
• prompt_logging_max_age: 90 days (older entries auto-deleted)
• prompt_logging_max_messages: 1000

Compatible With

• Drupal core ~11.3.0

Why This Matters for Varbase Enterprise Clients

Varbase targets enterprise Drupal deployments. Enterprise clients require:

• Compliance evidence — ai_logging + ai_observability provide the audit trail.
• PII protection — GDPR requirement for EU clients.
• Liability control — legal teams need assurance AI won't generate legal/medical advice.
• Security hardening — prevents AI-assisted XSS via content injection vectors.
