Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward video-frame extraction guide that writes image frames to a chosen output folder, with ordinary storage-use cautions but no hidden or unsafe behavior found.

Before using it, choose a dedicated output folder and confirm you have enough free disk space, especially for long or high-resolution videos. Avoid reusing a folder with existing frame files unless overwriting same-named outputs is acceptable.

A.I.G

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

Finding

This markdown skill describes extracting and saving frames to an output directory, which affects user data/storage by creating many files. Although disk space is mentioned as an input requirement and limitation, there is no clear warning section telling users up front that running the skill will create or overwrite output files and may consume substantial disk space.
