Retention Drop Checker

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward guide for diagnosing short-video retention drops and does not show hidden access, persistence, or unsafe behavior.

Before installing, note that parts of the skill are written in Chinese and it may initially ask diagnostic questions in Chinese. Only provide retention exports, scripts, or screenshots you are comfortable sharing with the agent.

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 skill directs the interaction to begin in Chinese without asking for the user's language preference or honoring locale. This can cause misleading or inaccessible behavior, especially for users expecting English, and may degrade user trust or lead to misunderstanding of diagnostic guidance.
