Claude Code Agent System for Expo/React Native

---

🎯 What's This?

A production-ready system of 7 core AI agents (20-agent design) + 3 slash commands + automation hooks for building React Native mobile apps faster with fewer bugs.

📱 Built specifically for React Native/Expo mobile development. While the system can be adapted for other frameworks, all agents, prompts, and workflows are optimized for iOS/Android mobile app development.

Built for:

• Claude Code CLI v2.0.5
• Windows environments
• Cursor terminal users
• Expo SDK 50+ / React Native 0.74+

💡 Why I Built This

As a developer building production Expo/React Native apps, I faced recurring challenges that slowed development and caused production issues:

The Problems:

• ❌ Design inconsistencies - Hardcoded colors and spacing slipping through code review
• ❌ Accessibility violations - App Store rejections due to WCAG non-compliance
• ❌ Package version conflicts - "Works on my machine" issues breaking builds
• ❌ Performance regressions - Discovered too late, after users complained
• ❌ Security vulnerabilities - Found in production instead of development
• ❌ Manual code reviews - Taking 2-3 hours per feature

The Solution: Instead of relying on manual checks and memory, I built a systematic, AI-powered approach using Claude Code's agent system.

What This Represents:

• 100+ hours of research into Claude Code agent architecture
• Production experience with React Native best practices (2025)
• Real pain points from shipping 3 mobile apps to App Stores
• Proven patterns that reduced bugs by 35% and development time by 50%

The Result: A complete agent system that catches issues before code review, ensures accessibility compliance, prevents version conflicts, and maintains performance budgets automatically.

This isn't theoretical - it's battle-tested on production apps with 10K+ users.

🚀 Installation

Automatic Installation (Windows PowerShell)

Interactive Mode (Recommended - Easiest!)

The installer guides you through the process:

cd claude-code-expo-system\scripts
.\install-agents.ps1

# You'll see a menu:
# 1️⃣ Project-Scoped (team sync via git)
# 2️⃣ Global (personal use everywhere)

# Choose 1 or 2, press Enter
# If project: confirms package.json found, asks to proceed
# Installs to the correct location

---

Non-Interactive Mode (Skip Prompts)

For automation or when you know what you want:

Project-Scoped (Recommended for Teams)

• Agents installed in project's .claude/ folder
• Version-controlled, team-shared via git

# Navigate to your Expo/React Native project
cd C:\path\to\your\expo-project

# Force project scope (no prompts)
C:\path\to\claude-code-expo-system\scripts\install-agents.ps1 -Scope project

Global (Personal Use)

• Agents installed in ~/.claude/ folder
• Available in all projects

# Force global scope (no prompts)
cd claude-code-expo-system\scripts
.\install-agents.ps1 -Scope global

# If permission error:
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

Manual Installation

Project-Scoped:

# From your Expo project root
cp -r /path/to/ready-to-use/agents/* ./.claude/agents/
cp -r /path/to/ready-to-use/commands/* ./.claude/commands/
cp /path/to/ready-to-use/templates/CLAUDE.md ./CLAUDE.md

Global:

# Install to user directory
cp -r ready-to-use/agents/* ~/.claude/agents/
cp -r ready-to-use/commands/* ~/.claude/commands/
cp ready-to-use/templates/settings.json ~/.claude/settings.json

🎯 Project-Scoped vs Global

Agent Precedence

Claude Code checks for agents in this order:

1. Project agents (.claude/agents/ in your project) - HIGHEST priority
2. Global agents (~/.claude/agents/ in home directory) - Lower priority

Hybrid Approach: You can have BOTH! Project agents override global agents with the same name.

When to Use Each

Project-Scoped (Recommended for Teams):

• ✅ Team projects (agents shared via git)
• ✅ Project-specific customizations
• ✅ Different agent versions per project
• ✅ Automatic sync for team members

Global (Personal Use):

• ✅ Personal projects
• ✅ Consistent agents across all projects
• ✅ Quick setup
• ✅ Single installation for everything

---

💡 Usage Examples

Invoke Agents Automatically

User: "Check for hardcoded colors in my components"
→ Design Token Guardian auto-invoked

Invoke Agents Explicitly

User: "@security-specialist audit the payment flow"
→ Security Specialist runs OWASP Mobile Top 10 audit

Use Slash Commands

User: "/review src/screens/LoginScreen.tsx"
→ Multi-agent review (design, a11y, security, performance)

Complex Features

User: "I need @grand-architect to help implement offline mode"
→ Grand Architect creates plan, delegates to specialized agents

🔧 Customization

Creating Custom Agents

1. Create file: ~/.claude/agents/my-agent.md
2. Add YAML frontmatter:

   ---
   name: my-agent
   description: What this agent does
   tools: Read, Grep, Edit
   model: sonnet
   ---
   

3. Write system prompt
4. Test: @my-agent [task]

See COMPLETE-GUIDE.md for detailed customization instructions.

---

🆘 Troubleshooting

Agent Not Found

# Verify installation
ls ~/.claude/agents/

# Check agent name matches file
cat ~/.claude/agents/tier-1-daily/design-token-guardian.md

Permission Denied (Windows)

Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

Agents Not Auto-Invoking

• Make description more specific in agent YAML
