Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only skill for building KET English-learning apps, with no executable behavior or hidden authority.

Install this if Chinese-language guidance for building KET or beginner English-learning apps is useful to you. Review the educational and privacy implications yourself when implementing features like speech recording, AI assessment, progress tracking, or child-facing accounts.

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

Findings (1)

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The skill title and body immediately switch into Chinese and provide all guidance in Chinese, while the skill is for building English-learning applications and does not state that Chinese is optional or region-specific. This creates a language/locale policy concern because users are not given an explicit choice of language.
Content: No source excerpt is available for this finding.
