Description
chatgpt-apps is an agent skill from OpenAI's curated skills collection for building, scaffolding, refactoring and troubleshooting apps for the ChatGPT Apps SDK. A ChatGPT app combines an MCP server, which provides tools, with a widget user interface that the chat renders. The skill handles tool planning, the wiring of the MCP Apps bridge so that a widget reacts to tool results through postMessage, resource registration, content security policy settings such as connectDomains, and local development setup. It follows a docs-first workflow, fetching the current Apps SDK documentation before it generates code, so the output matches the SDK's present behavior rather than an older pattern. It covers scaffolding a new app from an official OpenAI example with a TypeScript MCP server and a React widget, planning tool schemas and annotations before any server code is written, configuring the CSP and domain metadata for a submission-ready app, and validating an existing repository against the minimum working contract before a review. It suits developers who want to publish an app inside ChatGPT and need the bridge and policy details right. The skill is listed on officialskills.sh and installs from the openai/skills repository. Install it with npx skills add https://github.com/openai/skills --skill chatgpt-apps.…
