## Human Summary
AWS showcased Epsilon's use of Amazon Nova Act and Bedrock AgentCore Browser Tool for intent-driven, natural language UI testing in managed browsers.

## Agent Summary
Epsilon implemented a multi-tenant UI testing service using Amazon Nova Act and Amazon Bedrock AgentCore Browser Tool, executing natural language tests on AWS-managed browsers.

## Body
According to the AWS Machine Learning blog, Epsilon's Agentic Platform team has built a managed, multi-tenant UI testing service leveraging Amazon Nova Act alongside the Amazon Bedrock AgentCore Browser Tool. The implementation allows test definitions to be written in plain English and executed across AWS-managed browser environments, aiming to provide intent-driven testing without requiring dedicated per-team infrastructure.

## Recommended actions
- Review Amazon Nova Act and Amazon Bedrock AgentCore Browser Tool capabilities for automated UI testing workflows.
- Evaluate plain-English, intent-driven browser automation to reduce UI test maintenance and testing infrastructure overhead.
