Tech Stack

• React 18 with TypeScript
• Vite for build tooling
• Tailwind CSS + Headless UI for styling
• Hero Icons for iconography
• React Router v7 for navigation
• React Markdown for content rendering
• Vitest + Testing Library for testing

Development

# Install dependencies
npm install

# Generate prompts.json from individual prompt files
npm run generate-prompts

# Start development server
npm run dev

# Build for production
npm run build

# Lint code
npm run lint

# Run tests
npm run test

Git hooks are configured to run ESLint automatically before each commit. If hooks are missing, run npm install to set them up.

Prompt data workflow

Prompt metadata and definitions now live in data/prompts/*.yaml. Each file contains the display information (name, title, description, arguments) and the full messages array for a single prompt. After editing any of these files, run npm run generate-prompts to regenerate public/prompts.json. The command is wired into the prepare, dev, and build scripts, but contributors should commit both the modified source files and the regenerated JSON.

MCP Compatibility

This project is fully compatible with the Model Context Protocol specification. Each prompt includes:

• name: Unique identifier
• title: Human-readable display name
• description: Clear explanation of the prompt's purpose
• arguments: Typed parameters with descriptions and validation
• messages: Structured content with role-based messaging

Usage

1. Browse Prompts: View all available prompts on the homepage
2. Search: Use the search box to filter by keywords
3. Configure: Click on a prompt to set up arguments
4. Copy: Use the copy button to get the rendered prompt text
5. Integrate: Use the JSON format directly with MCP-compatible tools
