Smart Downloader

Security checks across malware telemetry and agentic risk

Overview

This is a straightforward user-directed downloader that fetches listed URLs and saves them to a chosen folder, with no hidden persistence or credential behavior found.

Before installing, understand that this skill can download arbitrary URLs you provide and save files to a folder you choose. Use trusted URL lists, avoid passing sensitive headers unless needed, keep concurrency reasonable, and review downloaded files before opening them.

Finding
The skill advertises and relies on network access and local file reading (URL list from a file), but it does not declare permissions for those capabilities. Missing permission declarations reduce transparency and prevent proper policy enforcement or user review, which is risky for a downloader that can fetch arbitrary remote content and write files based on user-provided input.
