Free course breaks down Claude Code's harness engineering

Original: Took apart Claude Code, then turned it into a free course on harness engineering

An AI engineer has published a free course after dissecting Claude Code, Anthropic's coding agent, to understand how it works internally. The course focuses on harness engineering — the practice of building the scaffolding and tooling around large language models that turns them into reliable, agentic systems. It is drawing attention among developers interested in replicating the techniques behind one of the most popular AI coding tools.

Why now: Developers are eager to learn the architectural techniques behind Anthropic's widely used Claude Code agent.
