A Codex bundle that connects developer workflows to OpenAI Platform. It automates API key generation, manages Agents SDK projects, and assists with ChatGPT Apps.
Open on GitHubWhat openai-developers does
The bundle links OpenAI tooling with Codex. An .app.json connector connects directly to platform.openai.com, while bundled skills handle setup and debugging. Dedicated tools scaffold ChatGPT Apps SDK projects, evaluate Agents SDK code, and format chatgpt-app-submission.json for review.
Credential setup runs through a dedicated skill. The connector lets you choose the project and organization directly from the platform. The skill will not write keys to disk without local confirmation of the env path in the MCP dialog. Running the validation suite requires Node.js and Python.
