Multi-Agent Coding

A systematic methodology for building complex software with coordinated AI agents.

This repository demonstrates PRD-first development using Claude Code's multi-agent orchestration to build applications faster through parallel execution and contract-driven development.

What This Is

This project teaches a reusable process for AI-assisted development:

1. Start with a comprehensive PRD - Clear requirements enable everything else
2. Configure CLAUDE.md - Point to your PRD and planning agent
3. Define specialized agents - Each owns a specific domain with clear boundaries
4. Execute in parallel - Multiple agents work simultaneously
5. Integrate smoothly - Contracts ensure clean composition

Quick Start

Prerequisites

• Claude Code installed
• Claude Pro subscription

Try the Demo

Build the blackjack app with Claude:

# Clone the repository
git clone https://github.com/bufothefrog/multi-agent-coding.git
cd multi-agent-coding/blackjack-app
cp .claude/settings.local.json.example .claude/settings.local.json

claude
# Tell Claude: "Please implement the blackjack-prd.md"

Claude will read the PRD, discover the agent definitions in .claude/agents/, and orchestrate the build using specialized agents working in parallel.

Explore the methodology:

# 1. Read the PRD (the starting point)
cat blackjack-app/blackjack-prd.md

# 2. Review the configuration
cat blackjack-app/CLAUDE.md

# 3. Examine agent definitions
cat blackjack-app/.claude/agents/01-foundation.md

Adapt to your project:

cp agent-templates/CLAUDE.md.example your-project/CLAUDE.md
cp agent-templates/planning-agent.md your-project/.claude/agents/planning-agent.md
# Customize using subagent-template.md

Core Principles

1. PRD First - Comprehensive requirements enable parallel development
2. Contracts Enable Parallelism - Define interfaces before implementation
3. Clear Boundaries - Each agent owns a specific domain
4. Context Management - Chunk work to respect token limits
5. Easy Integration - Smooth composition validates the approach

Why This Works

Traditional Sequential:

• Build backend → Build frontend → Add features → Debug integration
• 3-4 weeks, tight coupling, painful integration

Multi-Agent Parallel:

• Define contracts → [Backend + Frontend + Features simultaneously] → Integration
• 1-2 weeks, loose coupling, smooth integration
