Security checks for vulnerabilities and agentic risk

Overview

This is a simple YouTube ads guidance skill with no code execution, persistence, or hidden data handling.

Before installing, consider whether you are comfortable with the skill activating on broad video-ad phrasing and reading limited project-context sections when those files exist. It does not run code or change ad accounts.

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 manifest description says to use the skill when the user 'wants to run YouTube ads' or 'optimize video ad creative,' in addition to a mixed list of trigger phrases. Phrases like 'video ads' and the general intent wording are broad enough to overlap with many advertising discussions, and the file does not provide exclusion conditions beyond organic YouTube.
