## What it is
A project-based open course (14 lectures, 8 projects) teaching harness engineering for AI coding agents, covering environment setup, state management, verification, and control mechanisms. Available in 15 languages under an MIT license.

## Use cases
- learn how to build harnesses for AI coding agents
- beginner tutorial for agentic AI engineering
- how to make LLM agents work reliably
- learn state management and verification for AI agents
- hands-on projects for building agent environments
- course on harness engineering from zero to one

## When to choose
- you are a beginner wanting a structured, project-based path into agent harness engineering
- you want free, multilingual educational material on making AI coding agents reliable
- you prefer learning through hands-on projects rather than reference docs

## When to avoid
- you need a production agent framework or library rather than a tutorial
- you are looking for advanced, cutting-edge agent research material
- you need a tool to deploy or run agents rather than learn the concepts
