Security audit

税务计算

Security checks for vulnerabilities and agentic risk

Overview

This is a static tax-calculation reference skill with broad tax triggers but no code execution, persistence, credential access, or data transfer behavior.

Installers should treat this as a tax reference aid, not a substitute for current professional advice. Confirm the applicable jurisdiction, tax year, and current law before relying on calculations or filing guidance, especially because tax rules change over time.

A.I.G

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

Vague Triggers

Finding

The skill explicitly instructs invocation for broad categories like 'tax-related tasks,' which can cause the agent to activate this specialized workflow during ordinary finance conversations that do not require it. Over-broad activation increases the chance of irrelevant policy application, mistaken tax guidance, and unintended handling of sensitive financial data in contexts where the skill was not needed.

Vague Triggers

Finding

Many trigger phrases are generic tax nouns such as '增值税', '企业所得税', and '个人所得税', which are likely to appear in informational, news, educational, or comparative discussions unrelated to using this skill. This can lead to unintended invocation, overconfident domain-specific responses, and propagation of stale or jurisdiction-specific tax logic without first confirming the user's exact scenario.
