# How-to: Build a RAG Agent

# Example Use Case: "Internal Policy Q&A"

This example walks you through creating a RAG Agent that answers questions based on your company's internal HR policies.

Step 1: Navigate to Expert Agent Studio and Start Building

Action: From your Purple Fabric workspace:

• Open Expert Agent Studio.
• Click + Build to create a new agent.

Step 2: Setup Agent

Configure basic details:

• Solution Name: Internal HR Policy Assistant
• Interaction Type: Conversation
• Visibility: Private (or appropriate for internal HR access)

Step 3: Select Template

In the "Prompt Template" dropdown, choose RAG.

Step 4: Add Perspective

Define the agent's role, persona, goals, and guidelines in the "Perspective" field.

• Example Perspective: "You are an HR Policy Assistant. Your role is to provide accurate and concise answers to employee questions based solely on the provided internal HR policy documents. If the answer is not in the documents, state that you cannot find the information."

Step 5: Link to Knowledge Garden

In the "Knowledge settings" section, select the EKG that contains your HR policy documents.

Step 6: Configure Retrieval Parameters

Go to "Advanced Retrieval Configurations" to fine-tune settings:

• Retrieval Strategy: Semantic Search (to find contextually relevant information)
• Chunk Size & Overlap: Adjust based on your document structure (e.g., 512 characters with 50 overlap for policy documents).
• Re-ranking: Enable for better relevance.

Step 7: Test and Publish

Thoroughly test the agent with various queries:

• Example Query 1: "What is the policy for sick leave?"
• Example Query 2: "Can I expense client entertainment?"
• Example Query 3: "What is the company's policy on remote work? (if not in documents)"

Review agent details and publish.
