Paywall Upgrade Designer

Security checks for vulnerabilities and agentic risk

Overview

This is a marketing copy skill for improving SaaS paywall screens, with no executable code or hidden system access.

Before installing, expect the skill to ask for business-sensitive marketing details such as current paywall copy, pricing, target customers, objections, and social proof. Use it when you specifically want paywall or upgrade-screen conversion advice, and avoid sharing confidential metrics or customer names unless appropriate.

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 skill's activation description is broad enough to match many ordinary requests about pricing, copy, and upgrade flows, which can cause the skill to trigger in contexts where the user did not explicitly ask for a full paywall-conversion workflow. Over-broad activation can lead to inappropriate skill selection, unnecessary collection of business-sensitive context, and reduced user control over when persuasive marketing guidance is applied.
