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 yylo.

  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

Did setup work in Codex?

No setup reports for Codex yet. Self-reported by signed-in visitors. Copying a command is not counted, and most installs are never reported.

Attested installs: Fewer than 10 attested installs of this plugin in week 2026-W43, so no number is shown. Counted from opt-in HOL Guard install reports, once per machine and runtime, and never mixed with the answers above. How install reports work.
