gaebalai's Claude Code Plugin Marketplace

Overview

This repository is a plugin marketplace for Claude Code that automates TDD (Test-Driven Development) based development workflows. It provides specialized agents, custom commands, and skills to streamline the entire development process, from GitHub Issue implementation to code review responses.

The marketplace format enables centralized management of multiple plugins and easy sharing with teams and communities.

Features

• TDD Automation: Automatically executes the test creation → implementation → quality check cycle
• GitHub Integration: Automates Issue implementation and review comment responses
• git worktree Utilization: Safe working environment isolated from the main branch
• Layered Architecture Compliance: Maintains consistent code structure
• Quality Assurance: Automatically runs lint, tests, and type checks
• Library Documentation Access: Integrated MCP servers for Next.js, shadcn, and other libraries

Installation

Prerequisites

• Claude Code CLI installed
• Node.js (if used in your project)
• Docker (if used in your project)
• GitHub CLI (gh)

Adding the Marketplace

Add to your Claude Code settings file (~/.config/claude/settings.json):

{
  "plugin_marketplaces": [
    "https://github.com/gaebalai/claude-code-marketplace"
  ]
}

Or add directly via Claude Code command:

claude marketplace add https://github.com/gaebalai/claude-code-marketplace

Installing Plugins

After adding the marketplace, included plugins will be automatically available:

claude plugin install gaebalai

MCP Configuration

The .mcp.json included in the plugin automatically configures the following MCP servers:

• chrome-devtools: Browser automation and DevTools integration
• serena: Codebase analysis and semantic operations
• context7: Library documentation retrieval (HTTP-based, no API key required)
• next-devtools: Next.js development tools and documentation
• shadcn: shadcn/ui component library integration

Marketplace Composition

This marketplace includes the following plugins:

gaebalai Plugin

An integrated plugin for automating TDD development workflows. Composed of five component types:

1. Agents (agents/) - Specialized sub-agents
2. Commands (commands/) - Custom slash commands
3. Skills (skills/) - Reusable skill prompts
4. Hooks (hooks/hooks.json) - Event handlers
5. MCP Servers (.mcp.json) - External tool integration
