Voice Extractor

Security checks for vulnerabilities and agentic risk

Overview

This skill is a plain Markdown guide for turning user-provided writing samples into a voice guide, with a privacy caution because it asks for potentially sensitive personal communications.

Before using it, provide only writing samples you own or are authorized to share, and redact names, secrets, client details, private Slack content, regulated data, and anything confidential.

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

Missing User Warnings

Medium

Confidence: 96% confidence
Finding: The skill explicitly solicits emails, Slack messages, and call or podcast transcripts, which commonly contain personal, confidential, or third-party information, but provides no privacy warning, consent requirement, or guidance to redact sensitive data. In this context, the omission is more dangerous because the skill is designed to ingest authentic private communications as its primary input, increasing the likelihood of oversharing sensitive content.
