Harness engineering: How structured workflows improve AI-assisted code development
By
Marco Rizzi
Summary
The article discusses "harness engineering" — a practice of designing structured environments and workflows for AI-assisted software development. The author shares their experience working on a multi-repository project (Rust backend, TypeScript frontend, Helm charts, performance tests) and how they learned that providing structured context rather than vague tickets leads to better AI-generated code. The piece introduces two key techniques that emerged from this journey, emphasizing that the quality of AI output depends heavily on how well you design the environment and context in which the AI operates.
