Cold Email Writer

Security checks for vulnerabilities and agentic risk

Overview

This is a simple writing-assistance skill for drafting cold emails, with no executable code, persistence, credential use, or hidden high-impact behavior found.

Safe to install as a writing helper. Users should provide only the prospect and business details needed for the draft, and review any generated outreach for accuracy, privacy, and compliance before sending.

A.I.G

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 activation guidance says only to tell the agent who you're emailing, what you sell, and what problem you solve, without defining specific trigger phrases, constraints, or exclusion conditions. In a README, this broad natural-language invocation description can overlap with ordinary conversation about emailing prospects and makes it unclear when the skill should activate versus not activate.
