Security checks for vulnerabilities and agentic risk

Overview

This is a coherent Minecraft building guidance skill with disclosed boundaries and no executable install or persistence behavior.

Before installing, note that this skill can advise on powerful Minecraft server capabilities such as OP commands, RCON, FAWE edits, and bot automation. Use those parts only on servers you control or where you have explicit admin permission.

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
