帝王纪年转换 / Emperor Year Converter

Security checks for vulnerabilities and agentic risk

Overview

This is a local Chinese imperial year conversion skill with bundled data and no hidden network, persistence, or privileged behavior.

Installers should expect a historical date-conversion utility centered on Chinese reign names. Use the batch mode only with files you choose, since it can write conversion results to a specified output path.

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
  • System Prompt LeakageDirect Leakage, Indirect Extraction, Tool-Based Exfiltration
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • 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

Low
Category
Not specified by scanner
Confidence
91% confidence
Finding

This Python file contains user-facing natural-language documentation entirely in Chinese and presents the tool interface and usage exclusively in Chinese. Under the policy criteria, forcing a specific language without user opt-in is a locale/language policy concern when no alternative language choice is offered.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
91% confidence
Finding

This JSON data file uses Chinese script for dynasty, emperor, and reign names throughout, which can effectively force a specific language/locale on downstream skill behavior if consumed as-is. Under the natural-language policy rule, locale-specific content should either offer user choice or be clearly documented as region/language-specific.
