Requirements
  • Install Codex and sign in before running skills. Use the official documentation if the application is not yet available.
  • Check the chosen plugin's requirements; some skills need additional tools or runtimes.
  • Use PowerShell on Windows or Bash/zsh on macOS/Linux. Interactive slash commands are entered inside the application.
  • Git and access to the configured repository are required. Registration can run from any directory; it fetches the source for you.

Add Faye Plugin Market

Run this once for the selected source. If the same source is already registered, reuse it. Adding a marketplace makes its plugins available to choose; it does not install them all.

Add marketplace · PowerShell
codex plugin marketplace add https://github.com/Fayegram-AI/plugin-market.git
Add marketplace · Bash / zsh
codex plugin marketplace add https://github.com/Fayegram-AI/plugin-market.git

What you should seeThe source is registered. Its native marketplace identity is faye-plugin-market.

Available plugins

Once the marketplace is added, you can stop here or install any of these plugins. Adding the marketplace does not install every plugin.

Confirm installation and start a new session

Check the plugins you selected are installed and enabled where the application exposes that state. The list command below is a quick confirmation, not a test of every skill.

Start a new Codex session, open its skill picker or Plugins interface, and choose a task from the installed plugin's skill guides. Read that skill's inputs and requirements before sending your request.

Codex skill requests may use $skill-name. Copy the example from the selected skill's guide, including any explicit invocation it requires.

List installed plugins · PowerShell
codex plugin list --marketplace faye-plugin-market
List installed plugins · Bash / zsh
codex plugin list --marketplace faye-plugin-market

What you should seeYour selected plugins are installed and their applicable skills can be found or explicitly invoked in a fresh session.

Other ways to install

Check an existing installation

Use this before adding a second source or when setup reports that the plugin already exists. Compare the names and source locations; reuse a matching installation.

Installed plugins · PowerShell
codex plugin list --marketplace faye-plugin-market
Installed plugins · Bash / zsh
codex plugin list --marketplace faye-plugin-market
Registered marketplaces · PowerShell
codex plugin marketplace list
Registered marketplaces · Bash / zsh
codex plugin marketplace list

What you should seeThe intended source and installed package are identified without removing other registrations.

Manage later

Refresh the Git marketplace

Refresh the source when you want to check for new package versions. Compare installed versions afterward; refreshing the catalog alone is not evidence that each installed plugin was updated.

Refresh marketplace · PowerShell
codex plugin marketplace upgrade faye-plugin-market
Refresh marketplace · Bash / zsh
codex plugin marketplace upgrade faye-plugin-market

What you should seeThe marketplace refresh succeeds; inspect the desired plugin's current and available version before changing its installation.

Enable or disable a plugin

Open /plugins inside Codex. Select an installed plugin and use the displayed enable/disable action. Disabling keeps the installation but makes its capabilities unavailable until enabled again.

Inside Codex
/plugins

What you should seeThe plugin browser shows the intended enabled state.
