Agent Harnesses for Coding: What Actually Matters
After building and iterating on several of these systems, one lesson stands out clearly. Once you have a reasonably capable model, the majority of reliability, safety, iteration speed, and user trust comes from the harness around it. The model supplies reasoning and tool-call intent. The harness supplies everything else that turns that intent into coherent, recoverable work on a real codebase.
