# Harness Engineering This repository is an **active attempt to formalize and implement Harness Engineering**—a mechanical, repo-enforced framework for making large (often agent-driven) code changes safe, reviewable, and incremental. Inspired by [OpenAI's work on Harness Engineering](https://openai.com/index/harness-engineering/), this project provides the scaffolding, tooling, and conventions necessary for humans to steer while agents execute. --- ## What is Harness Engineering? Harness Engineering is a set of constraints and feedback loops that enable high-throughput agent-driven development without architectural decay. It treats the repository as a **system of record** for everything agents need to know. Key insight from OpenAI's experience: > "What Codex can't see doesn't exist." Knowledge in Slack threads, Google Docs, or engineers' heads is illegible to agents. The solution: encode everything—architecture, taste, quality standards—into mechanical, verifiable structures in the repo itself. --- ## Core Principles
