Harness Engineering
Summary
Harness engineering surrounds AI-assisted code generation with deterministic tooling, agent-based review, and periodic entropy checks to keep AI-generated code coherent and correct. It defines three core components (context engineering, architectural constraints, garbage collection), a living HARNESS.md, progressive hardening, and a self-improving harness that learns from its operation. The article positions harness engineering as essential governance for AI-driven development.
