🎯 Context-aware development expertise for Claude Code
A curated collection of specialized plugin bundles that give Claude deep expertise in specific tech stacks. Switch seamlessly between React, Angular, Unity, and other development contexts by activating the right skills when you need them.
Perfect for developers who work across multiple tech stacks and want Claude to have the right expertise at the right time.
Status: ✅ Production Ready
Complete React development expertise:
Activates automatically when working with React components, JSX, hooks, or state management.
Status: ✅ Production Ready
Automated bundle creation tools:
Perfect for creating your own custom bundles or contributing to this marketplace.
# Clone to your preferred location
git clone https://github.com/YOUR_USERNAME/claude-skills-marketplace.git
cd claude-skills-marketplace
# Add this marketplace to Claude Code
/plugin marketplace add .
# Install the React bundle for React development
/plugin install react-frontend-bundle
# Or install dev toolkit to create your own bundles
/plugin install dev-toolkit-bundle
Start a conversation in your context:
For React bundle:
"I need to create a user profile component with Zustand state management"
For dev toolkit:
"Create a new bundle for Angular development"
Claude will automatically apply the appropriate skills!
/plugin list
One of the key benefits of this marketplace is switching between development contexts:
/plugin install react-frontend-bundle
/plugin uninstall react-frontend-bundle
/plugin install angular-frontend-bundle
/plugin uninstall react-frontend-bundle
/plugin install unity-gamedev-bundle
Why switch? Each bundle provides deep, specialized knowledge for its context. Having all bundles active simultaneously would create noise and slower activation. Switching ensures Claude has exactly the expertise you need, when you need it.

Use this agent when designing APIs, building server-side logic, implementing databases, or architecting scalable backend systems. This agent specializes in creating robust, secure, and performant backend services. Examples:\n\n<example>\nContext: Designing a new API\nuser: "We need an API for our social sharing feature"\nassistant: "I'll design a RESTful API with proper authentication and rate limiting. Let me use the backend-architect agent to create a scalable backend architecture."\n<commentary>\nAPI design requires careful consideration of security, scalability, and maintainability.\n</commentary>\n</example>\n\n<example>\nContext: Database design and optimization\nuser: "Our queries are getting slow as we scale"\nassistant: "Database performance is critical at scale. I'll use the backend-architect agent to optimize queries and implement proper indexing strategies."\n<commentary>\nDatabase optimization requires deep understanding of query patterns and indexing strategies.\n</commentary>\n</example>\n\n<example>\nContext: Implementing authentication system\nuser: "Add OAuth2 login with Google and GitHub"\nassistant: "I'll implement secure OAuth2 authentication. Let me use the backend-architect agent to ensure proper token handling and security measures."\n<commentary>\nAuthentication systems require careful security considerations and proper implementation.\n</commentary>\n</example>
