Codex Computer Use

The runtime is @oai/sky, imported through mcp__node_repl__js (available in this session).

First: read the official skill

The official skill is authoritative. Read it before any computer-use work:

~/.codex/plugins/cache/openai-bundled/computer-use/<version>/skills/computer-use/SKILL.md

Find the latest <version> directory.

Load the runtime (once per session)

Send this as ONE line through mcp__node_repl__js:

globalThis.sky = (await import("@oai/sky")).sky;
nodeRepl.write("sky: " + typeof sky);

Confirm the output says sky: object before continuing. The import connects to the SkyComputerUseService, which is already running.

Rules

• Send code as ONE line, or use @file:<path> with a trailing newline.

The runtime fires on newline; input without a trailing newline silently does nothing.

• Reuse the loaded sky runtime on later turns. Do not reinitialize.
• The first computer-use action may need approval in the app

(Settings → Computer use). Common apps such as Safari and Chrome are usually pre-approved.

• Prefer purpose-built connectors, APIs, and CLIs over computer use when

they exist. Computer use is for reading or operating app UI that nothing else can reach.

• Never start your own node_repl process and never write a side-channel

driver. Use the tool you were given.

If the tool is missing

Stop and report that mcp__node_repl__js is not in the tool list. Do not build workarounds.
