Security checks for vulnerabilities and agentic risk

Overview

This skill provides straightforward video download and frame extraction commands, with expected local file creation and no hidden or deceptive behavior found.

Install only if you intend to download media and create local output files. Use a dedicated folder, check matched files before batch commands, and remove forced overwrite flags unless replacing outputs is intentional.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Missing User Warnings

Low
Confidence
90% confidence
Finding
This markdown skill instructs users to download videos and extract frames, which creates files on disk and can affect storage usage, but the description does not clearly warn that the commands will write multiple output files locally. While later notes mention storage size, there is no explicit user-facing warning near the main description about filesystem modifications or overwrite behavior.

Missing User Warnings

Low
Confidence
86% confidence
Finding
The batch examples iterate over broad filename globs and write derived files in bulk, including one command that forces overwrite with `-y`. In an agent context, this can cause unintended large-scale filesystem changes, clutter, or loss of existing output files if run in the wrong directory.
