What its author says it does

Copied from the file, not written here

Implement OpenAI Harness Engineering practices in any repository — AGENTS.md, PLANS.md, deterministic smoke/test/lint harness commands, strict architecture boundaries, observability from day 1, and entropy-control audits for reliable autonomous agent runs.

Harness Engineering Playbook

A skills.sh-compatible skill that operationalizes the practices from OpenAI's Harness Engineering guide. Use it to set up or refactor agent-first workflows so that autonomous runs are repeatable, observable, and safe.

Install

npx skills add broomva/harness-engineering-skill --skill harness-engineering-playbook

What It Does

Bootstraps harness artifacts: AGENTS.md, PLANS.md, docs/ARCHITECTURE.md, docs/OBSERVABILITY.md, Makefile.harness, and CI workflows.
Wraps deterministic commands behind make smoke, make check, make ci so agents can run them reliably.
Enforces strict module boundaries and data-shape contracts.
Wires structured observability (correlation IDs, key transitions) from day 1.
Adds entropy-control audits and nightly harness checks to prevent docs drift and flaky scripts.

Workflow

Baseline the target repo — detect language, toolchain, and existing CI.
Bootstrap harness artifacts from templates (interactive wizard or shell script).
Apply the nine Harness Engineering practices across repo artifacts.
Validate with audit — treat any MISSING or FAIL as blocking.
Iterate after real agent runs — patch gaps and re-audit.

Quick Start

# Interactive wizard (recommended)
python3 .agents/skills/harness-engineering-playbook/scripts/harness_wizard.py init <repo-path> --profile control

# Shell fallback
./scripts/bootstrap_harness.sh <repo-path>

# Audit
python3 .agents/skills/harness-engineering-playbook/scripts/harness_wizard.py audit <repo-path>

Profiles

Profile	Scope
`baseline`	Core harness artifacts only
`control`	Baseline + control-system primitives
`full`	Control + entropy controls, nightly audit, CI
