Security checks for vulnerabilities and agentic risk

Overview

This skill is a local wastewater billing spreadsheet checker whose code matches its stated purpose and does not show network access, persistence, credential use, or hidden behavior.

Install only if you are comfortable running a local Node-based checker on wastewater fee settlement data. Review the disclosed free-version limits: it performs table arithmetic checks and does not verify legal compliance, water-quality truth, monitoring equipment, or the paid-tier checks listed as withheld.

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
Vulnerability Patterns
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Finding

The skill uses 'env' capability that is not listed in its permissions. This may indicate deceptive intent or missing permission declarations.

Confidence

Finding

The file-level docstring and all user-facing guidance/messages are written exclusively in Chinese, including the contract, warnings, remediation text, and result notes. There is no indication that the skill is region-specific by policy or that users may opt into another language, which can violate a language/locale choice policy.

Finding

The script's docstring, help text, prompts, and operational messages are all presented exclusively in Chinese. Under the policy for natural-language violations, forcing a specific language without giving the user a choice can be a locale/language policy issue.

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)”,但该技能清单、帮助文本和其余注释都将输入限定为污水处理运行与水质数据材料、表头、若干行等核对资料。这里的内联文档把处理对象举例成“合同全文”,会让人误解该技能也面向合同类文档,与代码整体意图说明不一致。
