Tweet Writer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed tweet-writing helper that uses web research and copywriting guidance, with no code execution, persistence, credentials, or automatic posting behavior found.

Install this if you want an assistant to draft and optimize X posts using public web research. Avoid sharing private campaign details unless you are comfortable with those terms being used in web searches, and review generated persuasive content before posting.

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 description is broadly phrased around writing tweets, threads, and X content strategy, which can cause the skill to activate for many ordinary social media requests even when narrower or safer tooling would be more appropriate. Over-broad activation increases the chance the agent invokes web research and persuasive-content generation in contexts the user did not explicitly request, which can lead to unnecessary data exposure, unintended tool use, or policy-bypassing behavior through prompt collision.
