Security audit
Policy Brazil
Security checks for vulnerabilities and agentic risk
Overview
This skill appears to be a documentation-only helper for Brazil trade policy questions, with no evidence of hidden execution, data access, or destructive behavior.
Before installing, users should understand that this is a Chinese-language trade policy helper and its policy outputs are only references from public sources, not legal advice. For current tariff, ANVISA, INPI, or ICMS decisions, verify against official Brazilian sources.
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’s user-facing name and description combine Chinese text with a Brazil-focused title, but the document does not state whether responses will be localized or whether users can choose their preferred language. Under the policy rule, language or locale constraints should either be optional or clearly justified to avoid forcing a language experience implicitly.
