Security checks for vulnerabilities and agentic risk
Overview
This is a local Chinese tax late-fee table checker whose code and instructions match its stated purpose and do not show hidden network, persistence, credential, or destructive behavior.
Install only if you are comfortable running a local Node-based checker with Bash. It appears to keep data local and requires no API key or registration, but its output is mainly Chinese and it is limited to arithmetic and table-consistency checks, not legal or tax authority determinations.
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 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
- Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Natural-Language Policy Violations

- Confidence
- 93% confidence
- Finding
This JavaScript skill’s comments, sample input, error/advice text, findings, summary note, and disclaimer are all written exclusively in Chinese, and the expected input schema is also described only in Chinese. Under the stated policy, forcing a specific language without user opt-in is a natural-language policy violation unless a locale constraint is clearly documented and justified, which is not present here.

- Confidence
- 96% confidence
- Finding
The user-facing description, usage text, error messages, and outputs are entirely in Chinese, and the skill does not indicate any option to select another language or locale. Under the policy, forcing a specific language without user opt-in is a natural-language policy violation unless the constraint is explicitly documented and justified as region-specific.

- Finding
The JSON content is entirely in Chinese and presents a fixed-language template without any indication that the user can choose another language or locale. Under the policy, forcing a specific language without opt-in can be a natural-language policy violation unless the locale constraint is explicitly documented and justified.

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）”，但该技能的 manifest 与其余代码都表明输入应为滞纳金计算表或相关表格文本，而非合同全文。这会对开发者传达错误的技能意图，暗示更广泛的文档处理范围，与实际用途相矛盾。
