Security checks for vulnerabilities and agentic risk

Overview

This is a simple Amazon listing-writing skill with no code execution, persistence, credential use, or hidden data access.

Installers should understand that this skill is narrowly for English Amazon listing copy and may default to a US-style sales voice unless they specify a target market or tone. It does not appear to access private data or run code.

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

Vague Triggers

Medium
Confidence
91% confidence
Finding
The manifest description lists triggers such as "listing optimizer," "listing rewrite," and "amazon product copy," which are relatively generic and could overlap with ordinary ecommerce writing requests rather than clearly scoped invocations. The file does not provide exclusion conditions or negative examples to clarify when the skill should not activate.

Natural-Language Policy Violations

Medium
Confidence
84% confidence
Finding
The skill promises a complete English Amazon listing and states "No direct translation" and "Copy that converts," while later emphasizing writing for "Western buyers." This indicates a forced language/locale and market register by default rather than offering the user a choice of language or localization behavior.

Natural-Language Policy Violations

Medium
Confidence
88% confidence
Finding
The text says the skill rewrites for the "Western buyer's mindset" and "natural English register," which imposes a specific locale/cultural framing. Because the file does not offer alternative audience or locale options beyond a market default, this is a natural-language locale policy concern.
