Security checks across malware telemetry and agentic risk

Overview

This is a straightforward Douyin video downloader that makes expected network requests and saves requested videos locally.

Install this only if you want your agent to contact Douyin-related endpoints and save requested videos under ~/Downloads. Use explicit download requests, check the saved filename/path, and only download content you are allowed and comfortable storing locally.

Missing User Warnings

Low
Confidence
93% confidence
Finding
The skill instructs the agent to download remote content directly to `~/Downloads/` without any explicit user confirmation, path safety guardrails, or warning that local disk will be modified. While the write target is not attacker-controlled in the template, it still causes an external network fetch followed by a local file write, which can surprise users, consume disk space, and store untrusted media on the host.

Vague Triggers

Medium
Confidence
88% confidence
Finding
The usage guidance allows activation from very broad natural-language requests such as pasting share text and saying 'download it', without defining clear trigger boundaries, confirmation requirements, or scope checks. In an agent environment, this can cause unintended skill execution on conversational content or third-party text, leading to unreviewed network access and local file writes.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The skill states that downloaded files are automatically saved to ~/Downloads using the video title as the filename, but it does not warn about local file creation, possible filename collisions, privacy exposure, or user consent. This is dangerous because it can silently create artifacts on disk, overwrite or clutter user files, and store potentially sensitive or unwanted media in a predictable location.
