Security checks for vulnerabilities and agentic risk

Overview

This is a coherent Chinese-language exam-writing correction skill with no code execution, persistence, credential access, or hidden high-impact behavior.

Safe to install for Chinese-language English exam writing correction. Users who want feedback in another language should explicitly request that, since the current skill defaults to Chinese report structure and labels.

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
88% confidence
Finding

The manifest name, description, and all operational instructions are entirely in Chinese, with no indication that users may interact in another language or request a different locale. Under the policy, forcing a specific language without offering choice or documenting a justified locale constraint is a natural-language policy violation.

Natural-Language Policy Violations

Confidence
89% confidence
Finding

The entire skill specification is written as a prescriptive Chinese-only scoring and reporting standard, including fixed Chinese report headings and labels. There is no indication that the user may choose another language or locale, which can violate a language/locale policy when applied broadly.
