codex-computer-use
Control local apps through Computer Use (the @oai/sky runtime) inside the Codex app. Use when the session uses a custom (non-OpenAI) model, for example deepseek-v4-flash or mimo-v2.5, and the user asks to control the computer, operate a desktop app's UI, use Safari or Chrome through computer use, click or type in an app, or take a screenshot of an app. Prefer purpose-built connectors, APIs, or CLIs when they exist.

What this skill does
Codex Computer Use The runtime is @oai/sky, imported through mcpnoderepljs (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 mcpnoderepljs: 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 noderepl process and never write a side-channel driver. Use the tool you were given. If the tool is missing Stop and report that mcpnoderepljs is not in the tool list. Do not build workarounds. <!-- MCP:START --> <!-- PORTABILITY:START --> Cross-Client Portability This skill is written to stay usable across GitHub Copilot, Claude Code, and Codex.
