Security audit

Skill Extractor

Security checks for vulnerabilities and agentic risk

Overview

This skill is transparent about making local ZIP exports, but it can package broad local directories and real secrets into an archive if the user approves.

Before installing or using this skill, treat any generated ZIP as potentially sensitive. Review every external file path and avoid approving broad directories, credential stores, .env files, SSH keys, cloud config, package-registry tokens, logs, or personal documents unless you truly intend to share their real contents.

A.I.G

Vulnerability Patterns

Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
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
