OpenAI Codex release notes: 0.153 adds remote plugins to the CLI

OpenAI Codex CLI 0.153.0 can now list, install, and remove plugins from remote marketplaces. The command line can work with a remote catalog without requiring you to add the marketplace from Git or a local path first. The current stable version is 0.153.2.

Codex CLI is OpenAI's terminal-based coding agent. A plugin is an installable package that can add capabilities such as skills, tools, or connections, while a marketplace is the catalog where those packages are published.

OpenAI Codex release notes: remote marketplaces in the plugin CLI

codex plugin list now includes entries from remote catalogs. Its JSON output can show the source, version, installation policy, and authentication policy before you install anything.

Codex caches remote catalogs by scope and collection. If a plugin is missing from a fresh cache, the command fetches the catalog once more. A failed unfiltered remote listing does not remove the local curated catalog from the result. If you select a specific remote marketplace, however, Codex surfaces that marketplace's error.

Human step: list and install a remote plugin

Update Codex CLI first. Then list available plugins as JSON so you can inspect their metadata before installation.

npm install -g @openai/[email protected]
codex plugin list --available --json

After choosing a plugin, replace the placeholders with its real plugin and marketplace names:

codex plugin add PLUGIN@MARKETPLACE
codex plugin remove PLUGIN@MARKETPLACE

You can also pass the marketplace as --marketplace MARKETPLACE. The remove command uninstalls the plugin and deletes its local cache.

Short example: use the new Codex feature

Paste the list command's JSON output into Codex, then give the agent this instruction:

Review the plugin list above. Recommend at most one plugin for [task]. State its plugin ID, marketplace, version, installation policy, and authentication policy. If a field is missing, say so. Do not install or change anything.

A good response should:

• Choose a plugin that fits the stated task, or say that none fits.
• Copy metadata from the list without filling gaps.
• Leave installation as a separate human decision.

What patch version 0.153.2 changes

Version 0.153.2 corrects the GPT-6-Astra Fast tier description from "1.5x speed" to "2x speed, increased usage." OpenAI states that this is a display-text correction and does not change how requests run.
