节假日jiejiari

Security checks for vulnerabilities and agentic risk

Overview

This skill is a narrow China public-holiday lookup helper that reads bundled 2026 holiday data and does not show hidden, persistent, networked, or destructive behavior.

Install this if you want a China-focused 2026 public-holiday and make-up-workday lookup tool. Expect Chinese-oriented output and only bundled 2026 Mainland China data; it should not be treated as a global holiday calendar or a source for years not included in the package.

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

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The skill instructions are written as a directive to answer using Chinese ('用这个技能回答中国法定节假日放假安排与调休问题') and the examples and trigger terms are exclusively Chinese. Under the stated policy, forcing a specific language without user opt-in is a natural-language policy violation unless the locale constraint is explicitly documented and justified.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The natural-language instruction in the default prompt says to 'Use $jiejiari to answer' in English, while the skill metadata is otherwise in Chinese and does not offer the user any language choice. This creates a language-policy concern because the skill appears to impose a specific output language without explicit user opt-in or documented justification.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
95% confidence
Finding

The weekday formatter is hard-coded to use the "zh-Hans-CN" locale, and the rest of the user-facing strings are also Chinese-only. This is a natural-language policy concern because the skill enforces a specific language/locale without any opt-in or fallback mechanism.
