Codex

The desktop app has three modes: Chat, Work and Codex.

Either installation method lets you use Helm in the desktop app and terminal on this computer, except in Chat, which lacks the local project and terminal access Helm requires.

Desktop app

  1. Open the sidebar Plugins icon to reach Customize → Plugins.
  2. Choose Add → Add a marketplace. Enter myowinthein/agent-helm in Source, then click Add marketplace.
  3. Select Personal and find the Helm marketplace. Click + beside Helm to install it. It may appear as agent-helm or Agent Helm.
  4. Open Helm under Installed. Check its Version and that all ten skills are enabled.
  5. Start a fresh chat in your project workspace. Type $ and select a Helm workflow, such as log, test or ship.

Update

Terminal

codex plugin list --marketplace agent-helm-marketplace

Check the installed version and enabled state, then start a fresh session.
