# 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+ --- ## Table of Contents - [What's This?](#-whats-this) - [Why I Built This](#-why-i-built-this) - [Tech Stack](#-tech-stack) - [Quick Start](#-quick-start-10-minutes) - [What You Get](#-what-you-get) - [Real-World Impact](#-real-world-impact) - [Installation](#-installation) - [Usage Examples](#-usage-examples) - [Documentation](#-documentation) - [Customization](#-customization) - [Troubleshooting](#-troubleshooting) - [System Requirements](#-system-requirements) - [What's Included](#-whats-included) - [Contributing](#-contributing) - [License](#-license) - [Author](#-author) --- ## 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. --- ## ️ Tech Stack **Core Technologies:**    **AI & Automation:**   **Target Environment:**    **Development Tools:**    **Key Skills Demonstrated:** - AI Agent System Architecture - PowerShell Automation & Scripting - React Native/Expo Mobile Development - WCAG 2.2 Accessibility Standards - OWASP Mobile Security Practices - Performance Optimization Patterns - Software Engineering Best Practices --- ## Quick Start (10 Minutes) ### 1.

Easiest!)** The installer guides you through the process: \`\`\`powershell 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 \`\`\`powershell # 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 \`\`\`powershell # 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:** \`\`\`bash # 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:** \`\`\`bash # 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 \`\`\` --- ## Learning Path ### Week 1: Essentials - Install system - Use 3-5 basic agents - Try \`/review\` command - **Goal:** Get comfortable with agent invocation ### Week 2: Automation - Enable hooks for enforcement - Use \`/feature\` command - Try Grand Architect for complex tasks - **Goal:** Automate repetitive checks ### Week 3: Advanced - Multi-agent workflows - Custom slash commands - Performance optimization workflows - **Goal:** Master orchestration ### Week 4: Mastery - Create custom agents - Team collaboration setup - Metrics tracking - **Goal:** Full system proficiency --- ## Customization ### Creating Custom Agents 1.
