# Guardrails

The **Guardrails (Advanced)** tab in MagicBlocks gives you control over how your AI Agent handles sensitive data, inappropriate inputs, and compliance rules.

By configuring Guardrails, you ensure that your AI:

-   Follows factual and ethical guidelines
-   Redacts personally identifiable information (PII)
-   Detects unsafe or jailbreak attempts
-   Monitors content for moderation
-   Rewrites messages to comply with your set rules

This system ensures your Agent stays professional, safe, and accurate — no matter what users type.

## When to Use

Use the **Advanced Guardrails tab** when you want to:

-   Enforce brand, legal, or compliance rules across conversations
-   Automatically filter or redact personal or confidential data
-   Prevent unsafe, biased, or off-topic responses
-   Detect “jailbreak” attempts or manipulative prompts
-   Add moderation messages for sensitive conversations

This is especially useful for industries with strict standards — such as finance, healthcare, legal, or education.

## Advanced Guardrails Settings

### 1\. Rules

Rules define the behavior boundaries for your AI Agent.  
They ensure your Agent provides accurate, compliant, and responsible replies.

**Example rules:**

-   Acknowledge when information is unknown or unavailable.
-   Do not fabricate information if not available.
-   Do not provide estimates on pricing or rates unless stated.
-   Avoid giving advice outside of introduction services.
-   Maintain confidentiality of client information at all times.
-   Clearly communicate business offerings without exaggeration.
-   Direct users to a human representative for specific inquiries.
-   Ensure all claims about services are truthful and verifiable.
-   Never make up facts; avoid fabricating details or fake links.
-   Refrain from phrases like *“I can help you find...”* since there’s no access to real-time data.

Each rule works as a checkpoint — if the AI’s draft response violates one, MagicBlocks will auto-rewrite or fallback with a compliant message.

You can add new rules anytime by clicking **\+ New Rule** (up to 15 per Agent).

### 2\. PII Collection Control

**Purpose:**  
Control which personal or sensitive data your AI Agent can collect or display.

**How it works:**  
Use this dropdown to **Select PII to exclude from chat**, such as:

Names

Phone numbers

Email addresses

Credit card details

This helps you comply with privacy standards like GDPR or HIPAA.

### 3\. Redaction

**Purpose:**  
Automatically detect and hide sensitive information before it’s stored or processed.

**Options:**

**Off** — The AI will allow all information to pass through (no filtering).

**On** — MagicBlocks will redact selected PII from user or AI messages.

When **On**, you can select which information types should be redacted.  
Example: *3 Selected → Name, Email, and Phone Number.*

**Tip:** Keep redaction on for live or production Agents that handle user data.

### 4\. Rules Monitor

**Purpose:**  
Actively enforces Guardrail rules during chat.  
If the AI produces a response that breaks one, it will automatically rewrite it.

**Options:**

**Off** — Disables rule monitoring (AI responds freely).

**On** — Enables automatic rewrite to align with set rules. If rewriting fails, the Agent shows your fallback message.

**Example:**  
If your Agent tries to provide an estimate when “No Pricing Discussion” is enabled, it rewrites the message to:

> “I don’t have pricing information available, but I can connect you with our sales team.”

### 5\. Jailbreak Prevention

**Purpose:**  
Protects your Agent from malicious or manipulative prompts (e.g., “ignore all previous instructions,” “pretend you’re not an AI”).

**Toggle:**

**Off** — Jailbreak detection is disabled.

**On** — AI automatically detects and ignores unsafe prompts.

When enabled, this feature ensures users cannot trick the Agent into breaking company rules, accessing hidden data, or revealing restricted info.

### 6\. Moderation

**Purpose:**  
Filters inappropriate, offensive, or high-risk language before it reaches your users.

**Modes:**

**Select (Default)** — Use MagicBlocks’ default moderation filter.

**Custom** — Create your own moderation message for sensitive responses.

**Custom Message Example:**

> “Sorry, I can’t respond to that request. Let’s keep the conversation focused on how I can help you with our services.”

You can add snippets (`{user_name}`, `{agent_name}`) for personalization.

Personalize your **Moderation message** to keep tone consistent with your brand.

Combine Guardrails with **Memory Capture** to ensure secure, context-aware sessions.

## FAQs

**1\. Can Guardrails rewrite AI responses automatically?**  
Yes — with **Rules Monitor ON**, MagicBlocks auto-rewrites messages that break your rules.

**2\. What happens if redaction is off?**  
Sensitive information will be visible and stored in session logs. Only disable in testing environments.

**3\. How many custom rules can I add?**  
You can create up to 15 Guardrail rules per Agent.

**4\. What is a “Jailbreak” attempt?**  
It’s when a user tries to override the AI’s instructions (e.g., “ignore your rules,” “act like a human”). The system detects and blocks it automatically.

**5\. Can I use snippets in Moderation messages?**  
Yes — snippets personalize fallback or moderation replies dynamically.
