## 🎨 What is this Skills Marketplace?

This is a **comprehensive AI skills marketplace** that helps developers discover and compare AI coding agents. Think of it as a marketplace where you can find the best skills, commands, and capabilities across different AI tools.

**Tags:** `skills-marketplace` `ai-skills` `agent-skills` `mcp-servers` `ai-tools` `coding-agents`

## 🎯 Mission

The AI agent tooling landscape is exploding with multiple CLI-based coding agents (OpenCode, Codex, Claude Code, Cursor, Windsurf) each using different terminology and architecture patterns. This project serves as a **skills marketplace** and comparison hub to help developers understand which tool fits their needs and how concepts map between them.

**Example mapping**: "skills" in Codex ↔ "commands" in Claude Code ↔ "agents" in OpenCode ↔ "extensions" in Windsurf

## 🎨 AI Skills Marketplace

Welcome to the **AI Skills Marketplace** - a curated collection of 40+ AI skills for coding agents. This marketplace helps developers discover capabilities across different AI tools.

### Why a Skills Marketplace?

Different AI coding agents call their capabilities different things:

- **Codex** calls them "Skills"
- **Claude Code** calls them "Commands"
- **OpenCode** calls them "Agents"
- **Windsurf** calls them "Extensions"

This marketplace unifies them all so you can find what you need, regardless of the tool you use.

## 🚀 Quick Start (Local Development)

### Prerequisites

- Ruby 3.0+ with Bundler (recommended)
- Node.js 18+ (for build tooling)

> **Note:** If you have Ruby 2.6, you may encounter native extension compilation issues on macOS. See [Ruby 2.6 Workarounds](#ruby-26-workarounds) below.

### Installation

```bash
# Clone the repository
git clone https://github.com/odykyi/agentic-comparison.git
cd agentic-comparison

# Install Ruby dependencies (Ruby 3.0+)
bundle install

# Alternative for Ruby 2.6 users - use Docker:
# docker run -v $(pwd):/srv/jekyll -p 4000:4000 jekyll/jekyll:3.8

# Alternative for Ruby 2.6 - skip bundle install and use GitHub Pages:
# The site will work fine when deployed to GitHub Pages even without local bundle

# Install Node dependencies (for build tooling)
npm install

# Start local server
bundle exec jekyll serve --livereload

# For Ruby 2.6 without eventmachine (no live reload):
# bundle exec jekyll serve --no-watch
```

Visit `http://localhost:4000` to view the site.

### Ruby 2.6 Workarounds

If you're on Ruby 2.6 and experiencing native extension build failures (particularly with `eventmachine`):

**Option 1: Use Docker (Recommended)**

```bash
docker run --rm \
  -v $(pwd):/srv/jekyll \
  -p 4000:4000 \
  -e JEKYLL_ENV=development \
  jekyll/jekyll:3.8 \
  jekyll serve --watch --force_polling --livereload
```

**Option 2: Use the Docker Gemfile**

```bash
mv Gemfile.docker Gemfile
bundle install
bundle exec jekyll serve
```

**Option 3: Skip local setup and rely on GitHub Pages**
Since this is a Jekyll site for GitHub Pages, you can:

1. Push to GitHub
2. Enable GitHub Pages in repository settings
3. GitHub will automatically build and deploy the site
4. Make edits and view changes after deployment

**Option 4: Upgrade Ruby to 3.0+**
Using rbenv or rvm:

```bash
# Using rbenv
rbenv install 3.1.0
rbenv local 3.1.0
bundle install
```

# Install Node dependencies (for asset building)

npm install

# Start local server

bundle exec jekyll serve --livereload

````

Visit `http://localhost:4000` to view the site.

### Building for Production

```bash
# Build the site
bundle exec jekyll build

# The built site will be in `_site/` directory
````
