Plugin Creator

Overview

Scaffolds new Claude Code plugins with proper directory structure, required files, marketplace catalog integration, and full validation. Supports all plugin types: command plugins, agent plugins, skill plugins, MCP server plugins, and hybrid combinations.

Prerequisites

• Write access to the plugins/ directory and .claude-plugin/marketplace.extended.json
• jq installed for JSON generation and validation
• pnpm run sync-marketplace available at the repository root
• ./scripts/validate-all-plugins.sh available for post-creation validation

Instructions

1. Gather requirements from the user request: plugin name (kebab-case), category (productivity, security, devops, testing, etc.), plugin type (commands, agents, skills, MCP, or combination), description, and keywords. Default author to the repository owner if unspecified (see ${CLAUDE_SKILL_DIR}/references/plugin-creation-process.md).
2. Create the plugin directory structure under plugins/[category]/[plugin-name]/:

   plugins/[category]/[plugin-name]/
   ├── .claude-plugin/
   │   └── plugin.json
   ├── README.md
   ├── LICENSE
   └── [commands/ | agents/ | skills/ | hooks/ | mcp/]
   

3. Generate .claude-plugin/plugin.json using the template from ${CLAUDE_SKILL_DIR}/references/file-templates.md. Populate all required fields: name, version (default 1.0.0), description, author (name and email), repository, license (default MIT), and keywords (minimum 2).
4. Generate README.md with installation instructions, usage examples, a description section, and contributor information.
5. Create a LICENSE file with MIT license text (or the specified license).
6. Generate component files based on the plugin type:
   • Commands: create commands/[command-name].md with proper YAML frontmatter (name, description, model).
   • Agents: create agents/[agent-name].md with YAML frontmatter including field.
