Set up OpenAI's harness engineering methodology in any repository. Creates the
full agent-first infrastructure: AGENTS.md progressive disclosure map, architectural
layer boundaries with mechanical enforcement, testing framework, CI pipeline,
golden principles documentation, garbage collection scripts, and pre-commit hooks.
Use when asked to "set up harness engineering," "make the repo agent-ready,"
"add architectural boundaries," "set up testing and CI," or "adopt agent-first
engineering." Works with any stack — React, Next.js, Python, Go, Rails, etc.
