Security checks for vulnerabilities and agentic risk

Overview

This is a local-only Chinese membership-card ledger checker whose file reading and Bash usage are disclosed and proportionate to its purpose.

Install this only if a Chinese-language local checker for exported membership-card ledger tables fits your workflow. It reads the input file you pass to it and prints findings locally; review the stated free-version limitations before relying on the results for accounting decisions.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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

Natural-Language Policy Violations

Medium
Confidence
93% confidence
Finding
The file’s user-facing natural-language instructions, warnings, and outputs are entirely in Chinese, including the top-level description of what the tool does and how users must provide input. Under the policy, forcing a specific language without opt-in is a natural-language policy violation unless a locale constraint is explicitly justified, which is not stated here.

Natural-Language Policy Violations

Low
Confidence
89% confidence
Finding
The user-facing description, usage text, errors, and output strings are entirely in Chinese, which effectively constrains interaction to a specific language. The file does not indicate that other languages are supported or that the user can opt into Chinese, so this is a natural-language locale policy concern.

Intent-Code Divergence

Low
Confidence
94% confidence
Finding
The inline documentation states that non-JSON input will be handled as plain-text material, giving "直接粘贴的合同全文" as the example. That contradicts the skill's stated purpose and surrounding help text, which consistently require a membership-card sales/redemption detail table with headers, not arbitrary contract text.

Vague Triggers

Low
Confidence
89% confidence
Finding
This is a manifest file, so vague-trigger review applies. The only substantive field is a generic "text" blob containing tabular data, and there is no indication of what user request or context should activate the skill, nor any exclusion conditions or trigger boundaries.
