LATAM Timezone Briefing

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed, local-only Argentina/LATAM morning briefing skill with narrow file access and no executable code, network use, or credential handling.

Install this if you want an Argentina/LATAM-oriented morning briefing. Review the broad aliases if you often use greetings casually, and only place sensitive meetings or tax details in ~/centriqs/briefing/agenda.md or config.md if you are comfortable with the skill using them in private briefings.

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

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill advertises activation on very common conversational phrases such as "buenos días", "qué hay hoy", and "cómo arrancamos", which are broad enough to overlap with ordinary chat. This can cause unintended invocation of the skill, leading to surprise execution, incorrect routing of user intent, and possible leakage of contextual data into the skill when the user did not explicitly request it.

Vague Triggers

Category
Not specified by scanner
Confidence
91% confidence
Finding

The manifest description instructs activation on broad requests like 'resumen de la mañana', 'agenda del día', or an automatic heartbeat, which creates ambiguous matching criteria. In a multi-skill environment this can lead to accidental invocation, unintended data access, or the skill overshadowing other agent behaviors when users make ordinary scheduling requests.

Natural-Language Policy Violations

Medium
Category

Confidence
93% confidence
Finding

The file instructs the agent to always use ART and to never use UTC or MM/DD/YYYY, and later requires day names in Spanish. This is a language/locale constraint presented as unconditional behavior rather than a user-selectable preference, which can violate locale-choice policy.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill registers highly generic natural-language triggers such as common greetings and check-ins, which can cause unintended activation during ordinary conversation. That can make the agent inject briefing behavior and read local workspace data like agenda or config when the user did not explicitly request this skill, creating context confusion and potential privacy exposure.
