harness-kit

CLI scaffolding for project-owned agent harnesses.

Overview

What is harness-kit?

A CLI tool that scaffolds AI agent harness environments for projects. It distills best practices into artifacts you own directly, helping teams reduce setup drift with installable bundles and auditable diffs.

Who is it for?

For teams scaling AI coding guardrails across projects. It standardizes agent rules, skills, and harness state across repositories with a consistent baseline.

How do you use it?

Initialize once, add one capability at a time via bundles, and verify state with status checks. Artifacts are copied into your project—you own them.

Quick install

Start immediately with the latest CLI and run project initialization in one command.

Terminal
$npx @harness-kit/cli init

How installation works

Initialize once, add one bundle, and verify with status checks. The command shape stays consistent across bundles so onboarding is predictable for new contributors.

Terminal
$harness-kit add tdd
$harness-kit status

Features

Small, reviewable diffs
