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.

🧭 Don't know where to start?

Ask the CEO:

/mj-ceo "I want to build a user dashboard with auth"

The CEO estimates effort, decides which teammates to call (PM, Architect, Designer, etc.), and runs them in the right order. You just sit back and answer when they ask clarifying questions.

Build a new feature from scratch

/mj-clarify "add Stripe payments"     # PM: surface assumptions
   ↓
/MJ-plan "Stripe checkout + webhook"  # Architect: TDD plan
   ↓
… 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

Audit an existing site

/mj-design https://example.com    # Visual + UX review
/MJ-test https://example.com      # Security/SEO/perf/a11y

Just let the CEO drive

/mj-ceo "audit my landing page and tell me what to fix first"
