使用说明 (SKILL.md)

Cross-Platform Computer-Use Skill

Use this skill when the task needs a top-level portable computer-use skill that works across macOS, Windows, and Linux without depending on any local Claude installation, private native modules, or extracted app assets.

What this skill does

bundles standalone platform runtimes for macOS, Windows, and Linux
installs one top-level skill that contains all three platform payloads
selects the correct project for the current host platform
preserves the standalone bootstrap model: each platform runtime creates its own virtualenv and installs public Python dependencies on first real run
keeps platform-specific limitations explicit instead of pretending the hosts behave identically

Installed layout

After installation, assume the top-level skill lives at:

~/.codex/skills/cross-platform-computer-use-skill

The bundled projects are stored under:

~/.codex/skills/cross-platform-computer-use-skill/project/platforms/macos
~/.codex/skills/cross-platform-computer-use-skill/project/platforms/windows
~/.codex/skills/cross-platform-computer-use-skill/project/platforms/linux

Platform selection

Use the helper script from the installed skill root to resolve the active platform project:

bash ~/.codex/skills/cross-platform-computer-use-skill/scripts/current-project.sh

On PowerShell:

powershell -ExecutionPolicy Bypass -File $HOME/.codex/skills/cross-platform-computer-use-skill/scripts/current-project.ps1

Build

Always build the selected platform project, not all three at once:

cd "$(bash ~/.codex/skills/cross-platform-computer-use-skill/scripts/current-project.sh)"
npm install
npm run build

Run

cd "$(bash ~/.codex/skills/cross-platform-computer-use-skill/scripts/current-project.sh)"
node dist/cli.js

Validation notes

macOS has been real-device validated in this workspace, including GUI typing round-trip through the MCP type tool.
Windows and Linux are implemented, built, packaged, and published, but still need end-to-end runtime validation on real hosts.
Linux currently targets X11 first; Wayland can restrict screenshots, focus inspection, clipboard, and synthetic input.

Guardrails

Treat this host as trusted-local only.
Do not tell the user to search a local Claude install for binaries or hidden assets.
Be explicit about the current host platform and its validation status before claiming something is verified.
Mention that current runtimes report screenshotFiltering: none, so action gating is handled at the MCP layer.

安全使用建议

This skill is coherent: it bundles platform-specific runtimes that will run locally to take screenshots and control your mouse/keyboard. Before installing or running it, consider the following: 1) Review the included scripts (scripts/current-project.sh, scripts/install.sh, runtime/*) so you understand what will be executed. 2) Expect npm install and pip installs from public registries (PyPI/npm) on first run — run these in a controlled environment (VM/container) if you are risk-averse. 3) The runtime will access process information, window properties, and the filesystem under your home directory and will create a virtualenv and lock files; this is necessary for its purpose but is high-privilege local behaviour. 4) Do not install on hosts with sensitive data or credentials unless you trust the repository/author; prefer installing an official published package (ClawHub/GitHub) or verifying upstream source and checksums. 5) If you want extra safety, run the skill in an isolated VM or sandbox and audit any network calls or use of child processes in the code (search for exec/child_process usage) before granting it continued use.

功能分析

Type: OpenClaw Skill Name: cross-platform-computer-use-skill Version: 0.1.0 The skill bundle provides cross-platform GUI automation (computer-use) capabilities for macOS, Windows, and Linux. While these capabilities are high-privilege, the implementation includes extensive security controls and guardrails. Specifically, 'deniedApps.ts' implements a tiered permission system that restricts access to sensitive applications like browsers, terminals, and trading platforms, while 'keyBlocklist.ts' prevents the execution of dangerous system-level keyboard shortcuts (e.g., lock screen, quit app). The runtime bootstrapping process in 'pythonBridge.ts' and the platform-specific Python helpers ('linux_helper.py', 'mac_helper.py', 'windows_helper.py') are transparent and strictly aligned with the stated purpose of providing a standalone computer-use environment independent of local Claude installations.

能力评估

✓ Purpose & Capability

The name/description (cross-platform computer-use) matches the included files and runtime: Node TypeScript tool layer plus platform-specific Python helpers for screenshots, input, app/window enumeration, and an MCP server. The requested binaries/env/credentials are minimal and appropriate for the stated purpose (the project expects Node and Python and installs public Python packages at runtime).

ℹ Instruction Scope

SKILL.md instructs building and running the bundled platform project (npm install, npm run build, node dist/cli.js) and points at helper scripts to pick the correct platform. The runtime will enumerate displays/processes, take screenshots, control mouse/keyboard, and write local files (virtualenv, lock files) — all expected for a desktop-control skill but high-privilege operations on a local machine. The SKILL.md keeps host-local constraints explicit and does not instruct contacting unexpected external endpoints.

ℹ Install Mechanism

There is no platform 'install' spec in the skill registry, but the bundle contains full project code and scripts; first-run behavior auto-creates a Python virtualenv and pip-installs public packages from PyPI (mss, Pillow, pyautogui, psutil, python-xlib). npm install will fetch packages from the npm registry. Fetching/installing public packages and running build scripts is coherent for this use case but increases attack surface compared to an instruction-only skill with no code.

✓ Credentials

The skill does not declare or require any unrelated credentials or environment variables. It documents optional runtime environment flags (CLAUDE_COMPUTER_USE_*), which are appropriate for runtime configuration. The code reads/writes local files (home directory config and lock files) and queries process information (psutil) — proportional to enumerating running apps and enforcing a local lock.

✓ Persistence & Privilege

always is false and there is no evidence the skill requests permanent platform-wide privileges or attempts to modify other skills. It creates files under the user's home directory (virtualenv, lock/config dirs) which is expected for a local runtime. Autonomous invocation (model invocation enabled) is default behavior but not unusual; combine this with the runtime's capabilities only if you trust the code.
