Creating Custom AI Agents

Creating Custom AI Agents

Overview

While AIMatrix provides 50+ pre-built agents, the real power comes from creating custom agents tailored to your specific business needs. This guide will walk you through creating your first custom AI agent.

What is an AI Agent?

An AI agent in AIMatrix is an autonomous software entity that:

  • Observes - Monitors data and events
  • Decides - Makes intelligent decisions based on rules and ML models
  • Acts - Executes actions in BigLedger or external systems
  • Learns - Improves performance over time

Creating Your First Agent

Step 1: Choose Agent Type

AIMatrix supports several agent types:

Type Use Case Complexity
Rule-Based Simple if-then logic Low
ML-Powered Predictions and patterns Medium
Conversational Natural language interaction Medium
Hybrid Combines multiple approaches High
Multi-Agent Coordinates other agents High

Step 2: Define Agent Blueprint

Create a new agent using the AIMatrix Console or API:

from aimatrix import AgentBuilder

# Create agent blueprint
agent = AgentBuilder.create(
    name="Customer Churn Predictor",
    type="ml_powered",
    description="Predicts and prevents customer churn"
)

# Define inputs
agent.add_input(
    source="bigledger.customers",
    fields=["purchase_history", "support_tickets", "last_login"]
)

# Define model
agent.set_model(
    type="classification",
    algorithm="gradient_boosting",
    target="churn_probability"
)

# Define actions
agent.add_action(
    trigger="churn_probability > 0.7",
    action="send_retention_offer"
)

Step 3: Configure Data Sources

Connect your agent to BigLedger data:

    type: bigledger
    module: crm
    entities:
      - customers
      - transactions
      - interactions
    refresh: realtime
    
  - name: external_data
    type: api
    endpoint: https://api.social.com/sentiment
    auth: bearer_token
    refresh: hourly

Step 4: Design Decision Logic

    customer = context.customer
    
    if customer.lifetime_value > 10000:
        priority = "high"
    elif customer.recent_tickets > 3:
        priority = "urgent"
    else:
        priority = "normal"
    
    return {
        "priority": priority,
        "action": determine_action(priority)
    }

    features = extract_features(context)
    
    # Get prediction
    prediction = model.predict(features)
    
    # Interpret results
    if prediction.confidence > 0.8:
        return {
            "action": prediction.recommended_action,
            "confidence": prediction.confidence
        }
    else:
        return {"action": "human_review"}

            details=offer
        )
        
        return {"status": "sent", "offer_id": offer.id}
    
    @agent_action
    def escalate_to_human(self, customer_id, reason):

Best Practices

1. Start Simple

  • Begin with rule-based logic
  • Add ML capabilities gradually
  • Test thoroughly before production

2. Design for Failure

    except Exception as e:
        # Fallback logic
        result = fallback_action(data)
        log_error(e)
    
    return result

])

# Set up alerts
agent.add_alert(
    condition="accuracy < 0.8",
    action="notify_team",
    severity="high"
