🧰 What is harness-kit?

Your AI coding setup — plugins, skills, MCP servers, hooks, conventions — packaged into a single config you can apply to any tool on any machine. Build it once, share it with your team in one file.

📦 Install

/plugin marketplace add harnessprotocol/harness-kit

curl -fsSL https://raw.githubusercontent.com/harnessprotocol/harness-kit/main/install.sh | bash

⚡ Quick Start

Install explain — no dependencies, works in any codebase:

/plugin install explain@harness-kit

Then try it:

/explain src/auth/middleware.ts       # explain a specific file
/explain the payment processing flow  # search the codebase for a concept
/explain src/services/                # map a directory

Produces a layered explanation: summary, key components, how it connects, patterns, gotchas, and where to start if you need to change it.
