Security checks for vulnerabilities and agentic risk

Overview

This is a simple coupon-and-rebate shopping helper with no executable code, credential handling, persistence, or hidden behavior found.

Before installing, understand that this skill is aimed at Chinese-language coupon and rebate shopping workflows and may activate on broad savings-related phrases. Review rebate links and final prices yourself before purchasing, since the skill does not provide safeguards against outdated offers or biased rebate-channel recommendations.

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
Category
Not specified by scanner
Confidence
91% confidence
Finding

The trigger list contains broad, generic shopping phrases such as '省钱叠加' and '隐藏优惠券' that could match ordinary e-commerce conversations and invoke the skill unintentionally. In an agent setting, overbroad activation can cause the skill to run in contexts the user did not explicitly intend, increasing the chance of inappropriate coupon/rebate recommendations or unnecessary handling of shopping context.

Natural-Language Policy Violations

Low

Confidence
83% confidence
Finding

The skill name, description, headings, and output format all assume Chinese-language use, with no indication that users may opt into another language or locale. Under the stated policy, forcing a specific language without user choice can be a natural-language policy violation unless the locale restriction is explicitly justified.
