Building AI Agent Harnesses with Strands Agents

About this course

This course teaches developers how to build AI agents and agent harnesses using the open-source Strands Agents SDK. The course starts by teaching what the difference between an agent and agent harness is, and progresses from fundamental concepts (the agent loop, model providers, tools) through intermediate patterns (hooks, plugins, steering, conversation management) to advanced multi-agent orchestration (agents-as-tools, graph workflows, agent swarms) and finally agent operations (observability, evaluation, cloud deployment). Each video introduces a core SDK primitive with working code examples, building toward a complete mental model of how all primitives compose together into a custom agent harness. By the end of the course, learners will be able to design, build, evaluate, and deploy agent systems using any model provider.
