| description | Compatibility shim for Codex installs.

Route to install-agent-adapter with platform codex. |

Install the Understudy Codex plugin
This skill is a compatibility shim. The consolidated setup surface is
install-agent-adapter.
Procedure
Load install-agent-adapter and run it with platform codex.
Use its reference.md for the
current marketplace registration:
codex plugin marketplace add "$REPO"
Activation is in Codex:
/plugins
Choose understudy-skills, install or enable understudy, then ask:
Use the Understudy 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
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.
