Codex Plugins: Build & Install Reusable Workflows

Codex now supports plugins for packaging reusable skills, app integrations, and MCP configs. Scaffold with @plugin-creator, install per-user or per-repo, and share with your team.

Codex Plugins: Build & Install Reusable Workflows

TL;DR

  • Codex now supports plugins — installable bundles for skills, app integrations, and MCP server configs
  • Install plugins per-user or per-repo with simple JSON manifests
  • Use @plugin-creator to scaffold and test plugins locally before sharing

New

  • Plugin system — Installable bundles that package skills, app integrations, and MCP server configuration for reusable workflows across Codex app, CLI, and IDE extensions.
  • Plugin directory — Browse and install curated public plugins directly from the Codex app.
  • @plugin-creator skill — Scaffold new plugins, add local marketplace entries, and test them before sharing with teammates.
  • Flexible installation scopes — Install plugins per-user (~/.codex/plugins/) or per-repo (./plugins/) with corresponding marketplace configs.

How It Works

Every plugin is a folder with a required .codex-plugin/plugin.json manifest and optional supporting files for skills, app mappings, MCP configuration, and assets. Install plugins for yourself with ~/.agents/plugins/marketplace.json and ~/.codex/plugins/, or for your entire project with repo-local directories and .agents/plugins/marketplace.json.

To get started, use @plugin-creator to generate a plugin scaffold, test it in a workspace or home-scoped marketplace, then share it with your team. Full details are in the plugins documentation.
