# Plugin Creator

## Overview

Create and manage Claude Code plugins with proper structure, manifests, and marketplace integration. This skill provides workflows, automation scripts, and reference documentation for plugin development.

## When to Use This Skill

Trigger this skill when:

- Creating new plugins for a marketplace
- Adding or modifying plugin components (commands, skills, agents, hooks)
- Updating plugin versions
- Working with plugin or marketplace manifests
- Setting up local plugin testing
- Publishing plugins to marketplaces

## Quick Start

### Creating a New Plugin

Use the `create_plugin.py` script to generate plugin structure:

```bash
python scripts/create_plugin.py plugin-name \
  --marketplace-root /path/to/marketplace \
  --author-name "Your Name" \
  --author-email "your.email@example.com" \
  --description "Plugin description" \
  --keywords "keyword1,keyword2" \
  --category "productivity"
```

This automatically:

- Creates plugin directory structure
- Generates `plugin.json` manifest
- Creates README template
- Updates `marketplace.json`

### Bumping Plugin Version

Use `bump_version.py` to update versions in both manifests:

```bash
python scripts/bump_version.py plugin-name major|minor|patch \
  --marketplace-root /path/to/marketplace
```

Semantic versioning rules:

- **major**: Breaking changes (1.0.0 → 2.0.0)
- **minor**: New features, refactoring (1.0.0 → 1.1.0)
- **patch**: Bug fixes, docs only (1.0.0 → 1.0.1)

## Plugin Development Workflow

### 1. Create Plugin Structure

Manual approach if not using `create_plugin.py`:

```bash
mkdir -p plugins/plugin-name/.claude-plugin
mkdir -p plugins/plugin-name/commands
mkdir -p plugins/plugin-name/skills
```

### 2. Create Plugin Manifest

File: `plugins/plugin-name/.claude-plugin/plugin.json`

```json
{
  "name": "plugin-name",
  "version": "0.1.0",
  "description": "Plugin description",
  "author": {
    "name": "Your Name",
    "email": "your.email@example.com"
  },
  "keywords": ["k
