WhatsApp Styler

Security checks for vulnerabilities and agentic risk

Overview

This skill only teaches WhatsApp-specific message formatting and does not request system access, persistence, credentials, or code execution.

Install this when you want WhatsApp-ready formatting. Be aware it will discourage normal Markdown features like headers and tables, so it is best used only for messages intended for WhatsApp rather than general documents or code-heavy responses.

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

Findings (1)

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 84% confidence
Finding: The examples and required output format consistently prescribe Spanish-language content such as texto while describing strict formatting rules that must be followed. This can amount to a language/locale preference being imposed without any indication that the user may choose another language or opt in to that convention.
Content: No source excerpt is available for this finding.
