# Marketplace Update Skill

This skill provides functionality to update the `.claude-plugin/marketplace.json` file when plugins are added, modified, or removed from the marketplace.

## Purpose

Maintain the marketplace catalog by:

- Adding new plugin entries
- Updating existing plugin metadata
- Removing obsolete plugins
- Validating marketplace structure
- Ensuring consistency across the catalog

## When to Use

Use this skill when:

- A new plugin is created and needs to be registered
- An existing plugin's components change (agents, commands, skills added/removed)
- Plugin metadata needs updating (version, description, keywords, etc.)
- A plugin is being removed from the marketplace
- Validating marketplace.json structure

## Marketplace Structure

The marketplace.json file follows this schema:

```json
{
  "name": "marketplace-name",
  "owner": {
    "name": "Owner Name",
    "email": "email@example.com",
    "url": "https://github.com/username"
  },
  "metadata": {
    "description": "Marketplace description",
    "version": "1.0.0"
  },
  "plugins": [
    {
      "name": "plugin-name",
      "source": "./plugins/plugin-name",
      "description": "Plugin description",
      "version": "1.0.0",
      "author": {
        "name": "Author Name",
        "url": "https://github.com/username"
      },
      "homepage": "https://github.com/username/repo",
      "repository": "https://github.com/username/repo",
      "license": "MIT",
      "keywords": ["keyword1", "keyword2"],
      "category": "category-name",
      "strict": false,
      "commands": ["./commands/command-name.md"],
      "agents": ["./agents/agent-name.md"],
      "skills": ["./skills/skill-name"]
    }
  ]
