Security checks across malware telemetry and agentic risk

Overview

This skill is a disclosed Mac desktop automation tool, but it gives an agent broad control over your screen, keyboard, clipboard, browser, files, downloads, and shell commands without enough built-in safety gates.

Install only if you intentionally want a highly privileged Mac desktop-control agent and can supervise it closely. Review every shell command, file move, download, login/form action, and message before allowing it, and avoid using it with secrets or sensitive apps unless the skill is changed to require confirmations, constrain shell/file access, handle clipboard contents safely, and clean up screenshots.

Lp3

Medium
Category
MCP Least Privilege
Confidence
95% confidence
Finding
The skill exposes powerful shell-based file and network operations (`mv`, `cp`, `mkdir`, `curl`) while declaring no explicit permissions or safety boundaries. In a desktop automation skill with broad triggers, this creates a real risk of silent file modification, data exfiltration, or unintended command execution without the platform surfacing adequate user consent or policy checks.

Description-Behavior Mismatch

High
Confidence
98% confidence
Finding
The declared skill is for desktop automation, but the exposed toolset includes a generic shell executor, which materially exceeds that scope. This mismatch makes the skill far more dangerous because any caller expecting GUI-only automation can instead obtain arbitrary command execution on the host.

Vague Triggers

Medium
Confidence
93% confidence
Finding
The trigger phrases are extremely broad and match many ordinary requests involving opening apps, filling forms, moving files, or 'automatically completing' tasks. Because this skill can control the browser, keyboard, mouse, files, and shell, unintended activation could grant a highly privileged automation workflow to benign-seeming prompts, increasing the chance of unsafe actions being taken without clear user intent.

Missing User Warnings

Medium
Confidence
91% confidence
Finding
The skill provides templates for moving files and downloading remote content using shell commands, but it does not require warning the user about local data changes or outbound network access. In this context, the omission is dangerous because the skill is designed for direct desktop execution, so users may unknowingly authorize overwrites, bulk file movement, or retrieval of untrusted external files.

Missing User Warnings

High
Confidence
97% confidence
Finding
This code exposes silent shell execution with no user-facing warning, confirmation, or policy boundary. Because commands are arbitrary and run on the host, an attacker can perform destructive actions or steal data without any friction or visibility to the user.

Missing User Warnings

Medium
Confidence
87% confidence
Finding
The screenshot tool captures the user's screen and writes the image to disk without any disclosure about capture timing, contents, retention, or file location. In a desktop automation context, screenshots can contain credentials, personal messages, and other highly sensitive data.

Missing User Warnings

Medium
Confidence
90% confidence
Finding
This tool overwrites the clipboard and pastes its contents without warning the user, which can destroy user data in the clipboard and introduce unintended secrets or commands into the active application. In desktop automation, silent clipboard manipulation is particularly risky because it affects cross-application state.
