Skill Seo

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent local SEO/discoverability audit helper for skill packages, with no evidence of hidden execution, persistence, exfiltration, or destructive behavior.

Installers should understand that this skill may read and, when asked, edit the target skill's listing text and metadata to improve discoverability. Review proposed copy changes for accuracy so the skill is not positioned beyond what it actually does.

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
