Linkedin Post Writer

Security checks for vulnerabilities and agentic risk

Overview

This is a LinkedIn post drafting skill with no executable code, posting authority, credential access, or persistence.

Install only if you want Codex to draft LinkedIn posts using your local brand and voice materials. Review generated posts before publishing, especially for regulated claims, client confidentiality, and whether the broad LinkedIn trigger is acceptable in your skill set.

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 advertises very broad trigger phrases such as "LinkedIn" and "founder post," which can cause the agent to invoke this skill in situations where the user may have intended a different action or a more general social-media task. Over-broad routing increases the chance of misexecution, prompt hijacking via ambiguous requests, and accidental precedence over more appropriate skills, especially in systems with many overlapping skills.
