Security checks for vulnerabilities and agentic risk

Overview

This is a Portuguese copywriting-routing skill with broad activation terms, but it contains no code execution, credential use, persistence, or hidden data access.

Install this if you want a Portuguese-oriented copywriting assistant that routes work by marketing-copy type. Be aware that common trigger words like email or offer may activate it for some ambiguous requests, so clarify when you do not want copywriting help.

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

Vague Triggers

High
Category
Not specified by scanner
Confidence
97% confidence
Finding

The skill description says it should be used for 'QUALQUER solicitação de copywriting,' which creates an overly broad invocation surface. That can cause the agent to intercept many unrelated or borderline requests and impose its own routing/persona workflow, increasing the chance of prompt hijacking, instruction override, or unintended handling of sensitive business content.

Natural-Language Policy Violations

Medium
Category

Confidence
90% confidence
Finding

The skill content is written to operate in Portuguese and includes fixed response behaviors without any user opt-in for language preference. Enforcing a specific language can degrade transparency, cause misunderstanding of generated marketing content, and create a mismatch between user intent and skill behavior, especially when the skill is broadly invoked.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger list includes broad, common terms such as "copy," "email," and "offer," which can cause the skill to activate in contexts the user did not intend. In an orchestrator skill that routes requests to multiple specialists, accidental invocation can misroute user input, override more appropriate skills, and increase prompt-surface exposure across unrelated workflows.

Natural-Language Policy Violations

Low
Category

Confidence
88% confidence
Finding

The skill description is written only in Portuguese, which may impose a language/locale assumption without any opt-in or explanation that the skill is intended for a Portuguese-speaking context. This can conflict with language-choice expectations when no locale limitation is documented.
