Build AI agents and automate UI workflows from your web browser - Amazon Nova Act and Kiro

Source: Dev.to

Lesson Objectives

In this lesson you will learn how to:

1. Build an AI agent from UI‑automated workflows.
2. Identify use cases for Amazon Nova Act.

Amazon Nova Family

AWS introduces a family of AI offerings under Amazon Nova, which includes:

a) Amazon Nova 2 Foundation Models

b) Frontier Model

• Amazon Nova Forge – Allows you to combine your organization’s data with curated training data from Amazon Nova.

c) Automate Web‑Browser Workflows at Scale

Amazon Nova Act

Amazon Nova Act is an AWS service built on the architecture of Nova 2 Lite to create AI agents that automate web‑browser UI workflows. It enables you to:

• Build and manage AI agents for massive‑scale UI automation of repetitive tasks.
• Deploy agents quickly using natural‑language prompts and Python code.

Key Features

• Extract information from web pages.
• Confirm bookings and other transactions.
• Fill out forms automatically.
• Perform web searches and navigate results.

Benefits

• Completes repetitive tasks, launches APIs, and handles escalations.
• Takes a prototype to production in a matter of hours.
• Deploys and manages fleets of agents at scale.

Typical Use Cases

Getting Started with Amazon Nova Act

Prerequisites

1. Kiro – the agentic IDE.
2. AWS Builders ID (or IAM credentials).

Deployment Script (PowerShell)

# UTS Psychology Enrollment - AWS Deployment Script
param(
    [string]$BucketName = "uts-psychology-enrollment",
    [string]$Region     = "us-east-1"
)

Write-Host "=== UTS Psychology Enrollment - AWS S3 Deployment ===" -ForegroundColor Cyan
Write-Host ""

# Verify AWS CLI configuration
Write-Host "Checking AWS CLI configuration..." -ForegroundColor Yellow
aws sts get-caller-identity 2>$null
if ($LASTEXITCODE -ne 0) {
    Write-Host "ERROR: AWS CLI not configured. Run: aws configure" -ForegroundColor Red
    exit 1
}
Write-Host "✓ AWS CLI configured" -ForegroundColor Green

# Create (or confirm) the S3 bucket
Write-Host ""
Write-Host "Creating S3 bucket: $BucketName..." -ForegroundColor Yellow
aws s3 ls "s3://$BucketName" 2>$null

    aws s3 mb "s3://$BucketName" --region $Region
    if ($LASTEXITCODE -eq 0) {
        Write-Host "✓ Bucket created successfully" -ForegroundColor Green
    } else {
        Write-Host "ERROR: Failed to create bucket" -ForegroundColor Red
        exit 1
    }
}

# Sync local project files to the bucket
Write-Host ""
Write-Host "Syncing project files to S3..." -ForegroundColor Yellow
aws s3 sync . "s3://$BucketName" --exclude ".git/*" --exclude ".kiro/*"
if ($LASTEXITCODE -eq 0) {
    Write-Host "✓ Sync completed" -ForegroundColor Green
} else {
    Write-Host "ERROR: Sync failed" -ForegroundColor Red
    exit 1
}

Write-Host ""
Write-Host "Deployment finished!" -ForegroundColor Cyan

Next Steps

• Test the deployed workflow by invoking the generated Nova Act agent from a browser session.
• Monitor agent performance via the Amazon Nova Act console and iterate on prompts or specifications as needed.
