Can I customize the generated UI widgets?

Absolutely. The skill generates inline HTML/CSS templates for widgets (text/html+skybridge) that can be fully customized to match your specific data visualization needs.

Does this skill handle authentication?

Yes, it provides architectural guidance and implementation patterns for both single-user and multi-user authentication setups using providers like Auth0 or Supabase.

What technical stack does the builder use?

The skill generates a TypeScript project using Express, Zod for schema validation, and the official @modelcontextprotocol/sdk for server implementation.

Is the generated code ready for production deployment?

Yes, it includes a standardized file structure, environment variable management, build scripts, and health check endpoints suitable for modern cloud hosting.

What is a ChatGPT App in this context?

It is an application built on the Model Context Protocol (MCP) that allows ChatGPT to call custom tools and display interactive UI widgets directly in the conversation.
