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.

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: 96% confidence
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.
