SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill streamlines the development of interactive ChatGPT applications by providing a framework for creating shared UI widgets that both the human user and the LLM can interact with simultaneously.

Core Features & Use Cases

  • Zero-Config Widgets: Develop React-based UI components that automatically register with your MCP server.
  • Shared State Management: Synchronize widget state between the user interface and the LLM context for collaborative workflows.
  • Use Case: Build a flight booking assistant where the user selects seats on a visual map widget, and the LLM updates the booking status in real-time based on the widget's state.

Quick Start

Use the chatgpt-app-builder skill to scaffold a new project with the mcp-apps template.

Frequently Asked Questions about chatgpt-app-builder

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I build interactive ChatGPT apps with shared UI widgets?▼

Synchronizing widget state between a user interface and an LLM involves registering React components via the OpenAI Apps SDK. This allows real-time state updates so both the human and the model share the same context during complex UX flows.

Do I need the OpenAI Apps SDK to create React widgets for ChatGPT?▼

Yes, you need the OpenAI Apps SDK alongside mcp-use to handle widget registration and state management. These dependencies are required to enable zero-config React components to communicate with your MCP server.

How do I register React widgets with an MCP server?▼

You register React widgets with an MCP server by developing zero-config UI components that automatically connect through the mcp-apps template. This setup handles the underlying tool integration without manual configuration.

What is the best way to create a collaborative workflow between a user and an LLM?▼

The best way to create a collaborative workflow between a user and an LLM is using shared state management. This approach synchronizes UI interactions, like selecting seats on a visual map, directly with the LLM's booking context.

Can I use this skill for real-time state synchronization in complex UX flows?▼

Yes, you can use this skill for real-time state synchronization in complex UX flows. It specifically supports search, selection, and state synchronization between users and LLMs to maintain shared context during interactions.
