Build adaptive AI interfaces with the AG-UI protocol, agent swarms, and Nova Act on AWS

This article demonstrates how to build adaptive AI interfaces that automatically adjust to variable AI outputs using the AG-UI protocol, Strands Agents SDK swarms, and Amazon Nova Act for legacy system integration.

• AG-UI protocol provides standardized streaming for agent-to-UI communication over Server-Sent Events
• Strands Agents SDK Swarm pattern enables peer-to-peer multi-agent collaboration with visible debate and consensus building
• Amazon Nova Act performs browser-based automation for legacy system integration using natural language commands
• Complete radiology assistant example shows medical image analysis with three specialized agents debating findings
• Real-time visualization displays agent contributions, confidence progression, and consensus achievement across debate rounds
• HIPAA-compliant architecture with encryption at rest/transit, PHI minimization, and secure credential management
• Deployment uses Amazon Bedrock AgentCore, Lambda, DynamoDB, S3, and Cognito for authentication and state management

This approach eliminates custom integration code, reduces interface development time, and provides explainability through visible multi-agent collaboration for enterprise AI applications.
