# 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.
