create-rule

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward guide for creating project rule files, with its persistence behavior disclosed and tied to its stated purpose.

Before installing, understand that this skill helps create persistent project instructions for future AI sessions. Review any generated rule content, especially alwaysApply rules, because overly broad rules can affect later agent behavior across the project.

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
