Security checks for vulnerabilities and agentic risk

Overview

The skill is a local Chinese-language settlement checker that reads a user-provided file and runs deterministic calculations without network access, persistence, or data mutation.

Install only if you are comfortable using a Chinese-language local checker and understand the free version's limited scope. Before relying on it for payment approval, run --sample or --json and review checks_given/checks_withheld, because several higher-level checks are explicitly not included.

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

Intent-Code Divergence

Finding

The skill documentation contains an internal contradiction about which checks the free version performs: it earlier presents '同一达人同一场次重复结算' and '坑位费为零却有坑位约定' as behaviors users may see, but later says those checks are not included in the free version and that the full version differs only by those omitted checks. This is dangerous because users may rely on the free skill for financial control coverage it may not actually provide, creating a false sense of assurance and allowing billing errors or duplicate settlements to go undetected.

Natural-Language Policy Violations

Finding

The file’s natural-language comments, prompts, errors, notes, and disclaimer are entirely in Chinese, including all user-facing output strings such as the insufficiency messages and result note/disclaimer. Because the skill does not offer any language/locale opt-in or explain that it is intentionally limited to a Chinese-speaking/regional audience, it violates the language/locale policy criteria.
