Harness Engineering: A Systematic Approach to Taming AI Agents

As AI coding agents like Claude Code and Devin become more sophisticated, organizations face a critical challenge: unconstrained agents can cause scope creep, context confusion, and unintended code changes across projects. Harness Engineering offers a lightweight solution by embedding structured control systems—Markdown-based rules and verification loops—directly into repositories, drawing inspiration from proven software engineering principles. This approach makes AI agents more predictable and safer for professional development teams, addressing a gap between agent capability and practical usability in production environments.
