MJnCompany_2-0 — An AI Team You Hire Inside Claude Code
🇺🇸 English · 🇰🇷 한국어
TL;DR — One marketplace, eleven AI teammates. Install it once, and you can call a CEO, PM, Architect, Designer, QA Engineer, Code Reviewer, and DevOps engineer from inside Claude Code with simple slash commands like /mj-ceo or /MJ-test.
⚡ Optional: Install uv for 70%+ token savings on code analysis — brew install uv or curl -LsSf https://astral.sh/uv/install.sh | sh. Works without it too (automatic fallback).
🤔 What is this? (For Beginners)
Claude Code is Anthropic's official AI coding CLI. It supports plugins — bundles of slash commands, agents, and skills you install on top of it.
MJnCompany_2-0 is a marketplace that bundles 11 plugins, each one a specialist on a virtual AI team:
You ──▶ /mj-ceo "build a dashboard"
│
▼
🧭 CEO decides which teammates to call
│
┌──────────┼──────────┬──────────┐

🏗️ Plan 🎨 Design 🧪 Test 🚢 Ship
You don't need to remember which command does what — type /mj-ceo "your goal" and it dispatches the right teammates. Or call them directly when you know what you need.

… you implement code …
↓
/MJ-test https://staging.example.com # QA: 14-agent web test
↓
/MJ-codebase-review ./src # Reviewer: 5-agent code review
↓
/mj-ship # DevOps: pre-PR gate
