What you'll learn

What a “Harness” Really Means

The difference between agent tools (e.g., Claude Code) and the model that powers them.

Core Harness Components

Inputs, execution loops, tool use, logging, and iteration cycles.

Building Your Own Harness

A minimal, notebook-based approach to structuring AI workflows.

Why this topic matters

As AI tooling becomes more powerful, the limiting factor is no longer access to models but how effectively they are integrated into structured workflows. Harness engineering provides a way to make AI systems reliable, debuggable, and improvable over time. Understanding this pattern helps practitioners move from experimentation to disciplined, production-ready systems.
