Security audit

Czech

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Czech writing-style skill with no executable code, external access, persistence, or hidden high-impact behavior.

Install this if you want Czech responses to sound more native and informal. Be careful using it for business, legal, academic, customer-support, or elder/formal contexts because it intentionally pushes casual wording and may add slang or mild profanity unless the user asks for a formal register.

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 skill is explicitly scoped to producing Czech and instructs the model to default to a particular Czech register and style. Because the file does not indicate any user opt-in, language selection, or region-specific justification, this creates a natural-language locale policy concern.
