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
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
Install from the Plugins browser
Open Codex, open the Plugins browser, choose the marketplace registered by the previous command, and install authority-md-plugin.
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
