Cold Email Copy

Security checks for vulnerabilities and agentic risk

Overview

The skill is a simple cold-email writing prompt, but it embeds off-platform payment requests and advertises unreviewed extra scripts.

Install only if you are comfortable with a skill that includes embedded commercial upsell content. The reviewed artifact does not execute code, but any paid assets or Python scripts offered through the payment links are outside this review and should be treated as untrusted until separately inspected.

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
Vulnerability Patterns

Vague Triggers

Medium
Confidence
85% confidence
Finding
This markdown file describes activation through generic example prompts like "Create a follow-up sequence" and "Generate 5 cold email subject lines" without clearly defining trigger boundaries or exclusion conditions. The lack of explicit trigger scope or negative examples increases the risk that normal writing-assistance requests could unintentionally invoke this skill.

Description-Behavior Mismatch

Medium
Confidence
96% confidence
Finding
The skill metadata says it generates cold email copy, but the embedded content additionally solicits payment and advertises access to extra assets such as production-ready templates and Python scripts. This is a scope mismatch that can mislead users and downstream agents about the skill’s actual purpose, creating trust and supply-chain risk through undisclosed commercial or secondary functionality.

Context-Inappropriate Capability

Medium
Confidence
98% confidence
Finding
Including PayPal payment solicitation and a cryptocurrency wallet address in a skill whose purpose is only copy generation is unjustified and introduces social-engineering and financial-abuse risk. An agent or user could be steered into off-platform payments or trust the skill as an endorsed commercial offer, especially because the solicitation is embedded alongside normal usage guidance.
