### Billy Milligan — The Team Inside Your Head
5 toxic senior engineers trapped in one plugin. They argue, roast each other, and somehow deliver excellent technical decisions.

| Agent | Role | Model |
|-------|------|-------|
| **Viktor** | Senior Architect — draws boxes, quotes Fowler | opus |
| **Max** | Senior Tech Lead — ships it, asks questions later | opus |
| **Dennis** | Senior Fullstack Dev — grumpy, writes the actual code | sonnet |
| **Sasha** | Senior AQA Engineer — paranoid, everything will break | sonnet |
| **Lena** | Senior Business Analyst — sharpest person in the room | opus |

**20 commands**: `/plan`, `/debate`, `/review`, `/roast`, `/invite`, `/dismiss`, `/lang`, `/billy`, 7 memory commands (`/billy-save`, `/billy-recall`, `/billy-history`, `/billy-argue`, `/billy-context`, `/billy-forget`, `/billy-hall-of-fame`), 5 ADR commands (`/adr-new`, `/adr-list`, `/adr-review`, `/adr-status`, `/adr-supersede`)

**50 technical skills** across architecture, development, infrastructure, quality, product, and shared categories.

**Two-memory system**: Billy Memory (local, informal team chaos) + Project ADRs (formal, version-controlled decisions).

## Installation

### Install the entire marketplace
```bash
claude plugin marketplace add rnavarych/alpha-engineer
```

### Install individual plugins
```bash
claude plugin install alpha-core@alpha-engineer
claude plugin install role-backend@alpha-engineer
claude plugin install domain-fintech@alpha-engineer
claude plugin install billy-milligan@alpha-engineer
```

### Recommended combinations
```bash
# Backend developer working on fintech
claude plugin install alpha-core@alpha-engineer
claude plugin install role-backend@alpha-engineer
claude plugin install domain-fintech@alpha-engineer

# Frontend developer working on e-commerce
claude plugin install alpha-core@alpha-engineer
claude plugin install role-frontend@alpha-engineer
claude plugin install domain-ecommerce@alpha-engineer

# DevOps engineer for IoT platform
claude plugin install alpha-core@alpha-engineer
claude plugin install role-devops@alpha-engineer
claude plugin install domain-iot@alpha-engineer

# Any role + Billy Milligan (adds team dynamics to any setup)
claude plugin install billy-milligan@alpha-engineer
```

## Usage

### Invoke skills directly
```
/alpha-core:database-advisor
/role-backend:microservices
/domain-fintech:ledger-design
```

### Billy Milligan commands
```
/plan add user authentication
/debate Redis vs PostgreSQL for caching
/review src/components/Auth.tsx
/roast should we use GraphQL?
/adr-new "Database Choice"
```

### Agents activate automatically
Claude will delegate to the appropriate agent based on your task context. For example, asking about API design while `role-backend` is installed will activate the Senior Backend Developer agent.

## Architecture

```
alpha-core (foundation) ──┐
                          ├── Combined by Claude at runtime
role-<name> (persona)  ───┤
                          │
domain-<name> (domain) ───┤
                          │
billy-milligan (team)  ───┘
```

Each layer is independent and composable. Install only what you need.
