On March 26, OpenAI added plugins to Codex, its AI model for coding, giving developers a simpler way to package, share, and reuse workflows across projects and teams. For teams already using Codex for AI coding, the update reduces the setup work that is usually repeated from one machine to the next.
The plugin launch is only part of the picture. Codex already includes a wider set of features that make it more useful than a basic code assistant, and developers may be missing its importance.
Here are 10 Codex features developers should actually pay attention to.
1. Turn team setup into a reusable install
The clearest benefit of plugins is reuse. OpenAI says plugins can package skills, app integrations, and MCP server configurations for shareable workflows across the Codex app, CLI, and IDE extensions.
That gives teams a cleaner starting point. Instead of handing every new developer a long setup document and hoping they configure the same tools the same way, they can install one shared workflow and start from the same base.
