- # Install the Understudy Codex plugin

+ # Install the Orchestra Codex plugin

This skill is a compatibility shim. The consolidated setup surface is

[`install-agent-adapter`](../install-agent-adapter/SKILL.md).

## Procedure

Load `install-agent-adapter` and run it with platform `codex`.

Use its [`reference.md`](../install-agent-adapter/reference.md#codex) for the

current marketplace registration:

```bash

codex plugin marketplace add "$REPO"

```

Activation is in Codex:

```text

/plugins

```

Choose `orchestra-skills`, install or enable `orchestra`, then ask:

```text

- Use the Understudy onboarding skill for this project.

+ Use the Orchestra onboarding skill for this project.

```

## Safety Gates

Local-first and free: registering the Codex marketplace only makes local skills

available. It must not authenticate, upload data, inspect secret values, download

model weights, start hosted jobs, or make provider calls.

- Do not claim the plugin is installed when only the marketplace is registered.

- Do not edit `~/.codex/config.toml` by hand unless the user explicitly asks.

- Do not copy or fork skill content for Codex.

## Resolve CLI

- No Understudy CLI command is required. Use `codex plugin marketplace add` when

+ No Orchestra CLI command is required. Use `codex plugin marketplace add` when

available; otherwise show the manual `/plugins` activation path from

`install-agent-adapter/reference.md`.

## Output Standard

End with: that this routed through `install-agent-adapter`; whether the Codex

marketplace was registered/refreshed/shown for manual run; the `/plugins` step;

the next onboarding prompt; and the marketplace removal command.
