Security checks for vulnerabilities and agentic risk

Overview

This skill is a local Chinese land appreciation tax worksheet checker with no evidence of hidden network use, persistence, or unrelated system access.

Install only if you are comfortable running a local Node-based checker on tax worksheets. It does not provide tax advice or validate local policy rates, so verify its arithmetic output and any tax positions with the relevant source documents or a qualified professional.

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
