Security checks for vulnerabilities and agentic risk

Overview

This skill is a local, narrowly scoped checker for Chinese enterprise income tax adjustment tables, with no evidence of network access, persistence, credential use, or hidden behavior.

Install only if you need a Chinese enterprise income tax adjustment table arithmetic checker. It is a free local subset and explicitly does not check several tax-limit and legal-validity issues, so users should not treat a clean result as full tax compliance advice.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • 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

Confidence
90% confidence
Finding

The file’s user-facing natural-language documentation and messages are entirely in Chinese, and the sample input, prompts, advice, note, and disclaimer all assume Chinese-language interaction. There is no indication that users may choose another language or locale, which can violate a language/locale policy when opt-in is required.

Natural-Language Policy Violations

Confidence
94% confidence
Finding

The file's user-facing description, usage text, errors, and status messages are entirely in Chinese, including the capability name and help output. There is no indication that the user can choose another language or that the locale restriction is explicitly justified as a region-specific compliance requirement, which matches the language/locale policy-violation category.

Intent-Code Divergence

Confidence

Finding

The inline documentation states that non-JSON input will be treated as plain-text material such as a 'directly pasted full contract'. That contradicts the rest of the file, which consistently says the tool only checks enterprise income tax adjustment tables with headers and otherwise reports insufficient materials rather than analyzing unrelated document types.
