ChatGPT Apps

Overview

Scaffold ChatGPT Apps SDK implementations with a docs-first, example-first workflow, then generate code that follows current Apps SDK and MCP Apps bridge patterns.

Use this skill to produce:

  • A primary app-archetype classification and repo-shape decision
  • A tool plan (names, schemas, annotations, outputs)
  • An upstream starting-point recommendation (official example, ext-apps example, or local fallback scaffold)
  • An MCP server scaffold (resource registration, tool handlers, metadata)
  • A widget scaffold (MCP Apps bridge first, window.openai compatibility/extensions second)
  • A reusable Node + @modelcontextprotocol/ext-apps starter scaffold for low-dependency fallbacks
  • A validation report against the minimum working repo contract
  • Local dev and connector setup steps
  • A short stakeholder summary of what the app does (when requested)

Mandatory Docs-First Workflow

Use $openai-docs first whenever building or changing a ChatGPT Apps SDK app.

  1. Invoke $openai-docs (preferred) or call the OpenAI docs MCP server directly.
  2. Fetch current Apps SDK docs before writing code, especially (baseline pages):
    • apps-sdk/build/mcp-server
