Security checks for vulnerabilities and agentic risk

Overview

This skill is a documented router for AI safety sub-skills and does not itself perform hidden actions, data access, network calls, or persistence.

Installers should treat this as a table of contents, not a complete security product. Review each referenced sub-skill separately before relying on it, especially the confidential red-team kit and any guard that will inspect prompts, tool calls, MCP configs, or unpublished disclosure material.

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
