Install Guidance

Install in Codex

Install through the Codex CLI plugin marketplace.

Codex plugin docs

Optional: install HOL Guard for Codex first, so it can check this plugin's tools on your machine before Codex uses them.

  1. 1

    Register the marketplace

    Run in any terminal. Codex reads the marketplace entry from .agents/plugins/marketplace.json (or the legacy .claude-plugin path) in the repository. If the repository ships none, add the generated entry from the Advanced section below first.

    shell
  2. 2

    Install from the Plugins browser

    Open Codex, open the Plugins browser, choose the marketplace registered by the previous command, and install codex-honcho.

  3. 3

    Check the marketplace is registered

    This confirms the marketplace source only. Confirm the plugin itself is enabled in the Plugins browser before relying on it.

    shell
