What it installs
- Codex through mise, which pins and upgrades it the way it does a runtime and puts it on the path of every shell — including the non-interactive one a remote client opens.
- The same machine context, in ~/.codex/AGENTS.md, the same Pupitre skills, and the same MCP server, declared with codex mcp add.
What it asks you for
Nothing. It installs as it is.
Good to know
Your own subscription, again, and the same sign-in through a URL printed on first run. Claude Code and Codex can live on the same machine: they see the same projects, the same runtimes and the same databases, because there is only one machine. In the ChatGPT desktop app, Codex adds a remote project from a host alias of your ~/.ssh/config, so a Pupitre server reaches it through one host entry.
