What is the difference between Markdown-only and TypeScript implementations?

Markdown-only plugins are prompt-based and require no compilation, while TypeScript implementations support full CLI logic, unit tests, and complex MCP server tools.

What libraries are used in the generated scaffolds?

The scaffolds use Bun for runtime/package management, Biome for linting and formatting, and mcpez for simplified MCP server development.

How does the plugin registration work?

The tool automatically updates your marketplace.json and .claude-plugin directory to ensure your new plugin is recognized by Claude Code.

Can I add components to an existing plugin later?

Yes, you can use the Plugin Creator to add new MCP servers, commands, or skills to any existing project structure at any time.
