Acronym Unpacker

Security checks for vulnerabilities and agentic risk

Overview

This is a small local medical acronym lookup skill with no evidence of network access, credential handling, persistence, or hidden high-impact behavior.

This skill appears safe to install from a security standpoint, but users should treat its medical expansions as limited reference output rather than clinical advice; it covers only a small built-in English acronym list and some documented features are not implemented.

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
