chatgpt-plugin-builder
Design, scaffold, migrate, review, validate, and package ChatGPT and Codex plugins that combine reusable skills, MCP servers, registered MCP connections, lifecycle hooks, and optional MCP Apps UI. Use when the user asks to create a plugin, package skills into a portable plugin.json, add or connect an MCP server, migrate an older ChatGPT Apps SDK project, prepare a local marketplace entry, review plugin structure, or make a plugin ready for testing or submission. For detailed MCP server and widget implementation, use the installed OpenAI Developers app-building workflow when available and fetch current official plugin docs first.
