## Summary

**Amazon Bedrock AgentCore** lets developers build *ambient agents*—AI systems that react to real-time events like file uploads or database changes—without requiring human prompts. Unlike traditional chatbots, these agents trigger automatically when an event occurs (e.g., a file lands in S3) and pause for human input only when needed, such as for approval or clarification. The platform integrates with AWS services like S3, DynamoDB, and Lambda, enabling fully serverless workflows with long-running sessions and human-in-the-loop interactions via a single `askhuman` tool.

The reference implementation uses **Anthropic’s Claude Sonnet 4.5** model and supports extensions like scheduled jobs, API webhooks, or database changes. Key features include container-based execution, session isolation, and a React-based UI for monitoring jobs, responding to agent requests, and reviewing workflows. AWS claims the design lowers barriers to production deployment by combining event-driven triggers with structured human feedback. Developers must configure IAM roles, DynamoDB tables, and Lambda functions, but the platform abstracts away orchestration and state management.

## Key points

- AgentCore supports event-driven triggers (S3 uploads, scheduled tasks, API webhooks) with optional human review before execution
- Uses Anthropic’s Claude Sonnet 4.5 model by default, with switchable Bedrock models via config
- Human-in-the-loop interactions via a single `askhuman` tool, with job status tracked in DynamoDB

## Why it matters

Ambient agents automate repetitive workflows (e.g., document processing, monitoring) by reacting to events without manual triggers, reducing manual triage time. The integration with AWS services lowers setup complexity for enterprises already using the cloud, while the human-in-the-loop design mitigates risks of unchecked automation.
