code-quality-gate

agent-workshop

A plugin library and development framework for Claude Code. This repo serves two purposes:

1. Plugin Library — A custom marketplace of modular Claude Code plugins (skills, hooks, agents, MCP configs) installable via /plugin install.
2. Cookbook — Golden baseline configurations (CLAUDE.md templates, hook recipes, MCP setups) you can pull into any new project.

Quick Start

Install Plugins from This Marketplace

# Add the marketplace
/plugin marketplace add ats-kinoshita-iso/agent-workshop

# Browse and install plugins
/plugin install planning@agent-workshop

Use Cookbook Recipes

Browse cookbook/ and copy what you need into your project:

• cookbook/claude-md/ — CLAUDE.md templates by project type
• cookbook/hooks/ — Reusable hook recipes for .claude/settings.json
• cookbook/mcp/ — MCP server configurations for common integrations

Plugin Development Lifecycle

1. Develop in .claude/          →  Iterate locally with Claude Code
2. Validate with test suite     →  uv run pytest
3. Package as plugin            →  Create plugin.json + SKILL.md in plugins/
4. Auto-register in marketplace →  marketplace_gen.py updates marketplace.json
5. Users install from here      →  /plugin marketplace add ats-kinoshita-iso/agent-workshop
