Learn Harness Engineering: Open-Source Course for Reliable AI Workflows

Came across a practical open-source course on GitHub: Learn Harness Engineering

https://walkinglabs.github.io/learn-harness-engineering/en/

It breaks down collaboration with AI into 5 mechanisms: instructions, state, validation, scope, and sessions — each task becomes traceable, resumable, and verifiable, with no randomness in the results.

Course structure: 12 theoretical lessons + 6 practical projects; everything runs through a single desktop app that evolves as you build it.

It starts with basic comparative experiments, then gradually assembles a full-fledged working environment; the results of each project are used in the next one and strengthen the pipeline.

There are ready-made templates, so you can drop them straight into your project and start using them without taking the entire course.
