Security audit

Portuguese

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Portuguese writing-style skill with no code, persistence, network access, or sensitive data handling.

Install this if you want Portuguese output to sound more natural and casual. Specify Brazil vs. Portugal, region, and formality when needed, because the skill intentionally pushes toward informal native-style phrasing.

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

Natural-Language Policy Violations

Medium
Confidence
95% confidence
Finding
The skill is explicitly named "Portuguese" and instructs the model to "Write Portuguese" as a default behavior. This creates a language policy concern because it mandates a specific language/locale without stating that the user can choose another language or opt in to Portuguese output.
