Chinese Holidays

Security checks for vulnerabilities and agentic risk

Overview

This skill appears benign: it is a narrow offline Chinese holiday lookup tool with no network, credential, persistence, or file-changing behavior.

Install this only if you want China-specific statutory holiday lookups. For legal, payroll, travel, or business scheduling decisions, verify against current official announcements because the skill relies on bundled static data and may need annual updates.

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

Finding

The file describes itself as a Chinese statutory holidays tool and hardcodes Chinese holiday names and Chinese-language output fragments. Because the instructions require flagging language or locale policy violations across all file types, this is a natural-language locale constraint that is not presented as a user choice or explicit opt-in policy.
