Install plugin-ops for Codex

Installs for the current user
codex plugin marketplace add melodic-software/codex-plugins
codex plugin marketplace upgrade melodic-software-codex
codex plugin add plugin-ops@melodic-software-codex

Paste and run these commands in a terminal with Codex. They add and refresh the melodic-software-codex catalog, then install this plugin.

Compatibility: the page URL and API slug “plugin-ops” remain stable.

  • Codex: plugin-ops@agent-plugin-marketplace → plugin-ops@melodic-software-codex

The installer fetches third-party code from the source repository shown on this page. This directory validates manifest structure and source location, but does not perform a security audit; review the manifest, components, and source before installing.

Get the source manually
git clone https://github.com/melodic-software/codex-plugins

Clone the source repository, then follow its setup instructions to add the plugin to a compatible client. The plugin root is plugins/plugin-ops/.
