Controle Interno Municipal

Security checks for vulnerabilities and agentic risk

Overview

This is a Portuguese reference skill for Brazilian municipal internal-control work, with no executable code or hidden high-risk behavior found.

This skill appears safe to install for users who want Brazilian municipal internal-control guidance. Users should treat its legal and procedural content as jurisdiction-specific reference material, especially where it cites Maranhão/TCE-MA or current TCU rules, and verify deadlines and authorities before relying on it in official work.

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

Finding

The manifest description explicitly states "Idioma: Português do Brasil," which imposes a language/locale constraint in natural language. Although the subject matter is Brazilian municipal internal control, the file does not clearly frame the language restriction as an opt-in choice or explain that responses may still adapt to the user's preferred language.

Finding

This markdown file appears to require Portuguese for all user-facing content, but it does not state that the skill is region-specific or that users may choose another language. Under the policy, forcing a specific language without user opt-in can be a natural-language policy violation.
