Skill instructions

Build ChatGPT App 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.
