Original Description

Everybody's talking about AI agents — but how do you actually build one? In this hands-on tutorial, you'll learn what makes up an AI agent (model, tools, system prompt, and the agentic loop) and then build your own from scratch using the Strands Agents SDK and Python. What you'll build: - A basic agent in 3 lines of code - Custom tools using the @tool decorator - A system prompt to shape agent behavior - An MCP server connection for real-world tool use Resources: Strands Agents: https://go.aws/3QnE19c Strands Agents SDK: https://go.aws/4u88KWt Kiro: https://go.aws/4vP0Jaw Amazon Bedrock AgentCore: https://go.aws/4sKxW3V uv (Python package manager): https://go.aws/3OUUSQb Follow AWS Developers!
