Summary

The OpenAI `openai/plugins` repository offers a curated collection of Codex plugin examples, each structured with a mandatory `.codex-plugin/plugin.json` manifest and various optional companion surfaces such as `skills/`, `.app.json`, `.mcp.json`, `agents/`, `commands/`, `hooks.json`, and `assets/`. This repository showcases diverse applications, including a `figma` plugin for design system rules and Code to Canvas, a `notion` plugin for planning and knowledge capture, and `build-ios-apps` and `build-macos-apps` plugins for SwiftUI development, refactoring, and debugging. Further examples cover `build-web-apps` for deployment and database workflows, `expo` for React Native development and SDK upgrades, and `netlify`, `remotion`, and `google-slides` for public skill- and MCP-backed functionalities.

Key takeaway

For AI Engineers exploring custom tool integration, this repository provides concrete examples of how to structure and implement OpenAI Codex plugins. You can examine the manifest and companion files to understand extending AI capabilities into specific development, design, or productivity workflows. Consider adapting these patterns to build your own plugins for specialized tasks, enhancing automation and interaction with existing platforms like Figma, Notion, or various app development environments.
