Security checks for vulnerabilities and agentic risk

Overview

This skill is a local, read-only bank guarantee ledger checker with disclosed scope and no evidence of network use, persistence, credential access, or hidden behavior.

Install only if you are comfortable running a local Node script over bank guarantee ledger text. The skill does not verify whether a guarantee is genuine or provide legal advice, and it explicitly withholds several advanced checks from the free version.

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

Natural-Language Policy Violations

Medium

Confidence: 93% confidence
Finding: The JSON sample text is entirely in Chinese, including field headers and status values, with no indication that language selection is optional or that the skill is specifically limited to a Chinese-language context. This can violate a language/locale policy when users are not given an opt-in or alternative locale.

Intent-Code Divergence

Low

Confidence: 90% confidence
Finding: L075 的注释写明“不是 JSON 就当作纯文本材料（例如直接粘贴的合同全文）”，而清单与其余帮助文本都强调输入应为银行保函/保函台账含表头的数据。这里的注释把可接受材料扩展成“合同全文”示例，主动传达了超出该技能声明范围的输入意图，和技能定位存在文档层面的矛盾。
