Douyin Short Video Factory

Security checks for vulnerabilities and agentic risk

Overview

This is a small Douyin content-creation helper with a broad trigger but no hidden code, persistence, credential handling, or destructive behavior.

Before installing, be aware that mentioning Douyin generally may activate this skill. Use it when you actually want Douyin video creation, link parsing, hashtag help, or virality scoring, and only parse or download content you have permission to use.

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

The trigger phrase "douyin" is extremely generic relative to the skill’s scope and is likely to match many ordinary user requests that merely mention the platform, causing unintended activation. In a skill that can parse links, generate content, and operate across multiple Douyin-related workflows, overbroad invocation increases the chance of the agent selecting this skill in contexts the user did not intend, which can lead to incorrect actions, privacy issues around link processing, or confusing tool behavior.
