Security checks for vulnerabilities and agentic risk

Overview

This is a Markdown-only Reddit copywriting guide with a somewhat broad trigger, but it does not run code, persist data, or access sensitive information.

Before installing, be aware that the skill may activate for general Reddit mentions, not only explicit drafting requests. Its guidance is otherwise straightforward: it helps draft engagement-oriented Reddit copy and reminds the user to check subreddit rules; it does not post content or access accounts on its own.

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 invocation description is overly broad and can activate the skill whenever Reddit-related terms are mentioned, even if the user is not asking for Reddit copy generation. This can cause inappropriate skill routing, leading the agent to apply persuasive or engagement-oriented Reddit guidance in contexts where it is irrelevant or unsafe.
