Harness Docs

Harness Kit documentation — installation, plugin catalog, creating plugins, cross-harness setup, architecture, and FAQ. Use when working with or configuring harness-kit plugins, understanding the plugin/skill system, installing slash commands, setting up AI coding tool configuration, answering questions about the plugin marketplace, writing SKILL.md files, using harness.yaml, or integrating with Copilot, Cursor, or Codex. Do NOT use for general Claude Code questions unrelated to harness-kit.

Harness Kit Documentation

harness-kit is a harness-agnostic framework for AI coding tools. Plugins, skills, MCP servers, hooks, and conventions live in one portable config. It works with Claude Code today and is designed to travel across tools.

How to Use This Skill

This is a background knowledge skill. When the user asks about harness-kit, load the relevant reference file from ${CLAUDE_SKILL_DIR}/references/ and answer from it.

Topic	Reference file
Installation, architecture, quick start	`getting-started.md`
Plugin list, what each plugin does	`plugin-catalog.md`
Creating plugins, writing SKILL.md, frontmatter	`creating-plugins.md`
Using with Copilot, Cursor, Codex	`cross-harness.md`
Core concepts, FAQ, harness.yaml, comparison with MCP/A2A	`concepts-and-faq.md`

Load with: Read ${CLAUDE_SKILL_DIR}/references/<filename>.md

Key Concepts

Skill — A SKILL.md file: the workflow Claude reads when you type a slash command.
Plugin — The package wrapping a skill: a directory with plugin.json, the skill, optional scripts, hooks, and agents.
harness — Your complete AI tool setup: CLAUDE.md, plugins, MCP servers, hooks, permissions.
harness.yaml — A portable snapshot of your complete harness. Export with /harness-export, restore with /harness-import.

Install

/plugin marketplace add harnessprotocol/harness-kit
