Security audit

Security checks for vulnerabilities and agentic risk
Overview
This skill gives a coding agent a structured TDD workflow for implementing an approved SPEC and does not show hidden, destructive, or unrelated behavior.
Install this only if you want the agent to modify a repository according to an already approved SPEC using TDD. Review the SPEC first, because the skill treats it as the authority for continuing through implementation slices, and expect progress messages in Portuguese.
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 file explicitly requires that all questions and explanations to the user be in Portuguese (pt-BR). This is a natural-language policy concern because it forces a specific language for user interaction without offering the user a choice or documenting an opt-in.
