What is plugins?

This repository is a collection of example plugins built for Codex, OpenAI's coding agent. Each plugin lives in its own folder under a plugins directory, and every plugin must include a small manifest file that tells Codex what the plugin is and how to load it. Beyond that required manifest, a plugin can optionally include extra pieces such as skills, app configuration, settings for connecting to other tools through the Model Context Protocol, its own custom agents, commands, hooks that run at certain points, and any supporting assets it needs. A marketplace file lists which plugins are available by default, pointing back to the main plugins folder. There is a separate marketplace file specifically for people who log in using an API key rather than the standard login flow. The README highlights several of the richer examples included in the repository. There is a plugin for working with Figma designs, converting code to visual layouts, and connecting design systems to code. Another plugin supports planning, research, meeting notes, and general knowledge capture inspired by Notion. Additional plugins cover building iOS apps with SwiftUI, building macOS apps with SwiftUI or AppKit, deploying and building web applications including UI, payments, and database work, and building Expo and React Native mobile apps with support for SDK upgrades. A few more plugins connect Codex to Netlify, Remotion for video, and Google Slides. The README itself is short and mainly serves as an index pointing to the individual plugin folders, so most of the real detail lives inside each plugin's own files rather than in this top level document.
