A nano Claude Code agent harness framework teaching operators how to build AI agents from first principles.

About

Learn Claude Code is an educational framework and reference implementation for building agent harnesses—the operational infrastructure that enables Claude to perceive, reason, and act in real environments. It teaches the core pattern: model + tools + knowledge + observation + action + permissions. The repo includes code examples, architectural patterns, and a clear philosophy on what constitutes a real agent versus orchestration-theater.

Who it is for
