Chonk Chonk

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent virtual-pet helper that uses the advertised Animal House API, with limited account-token handling that users should treat carefully.

Before installing, understand that this skill creates and controls an Animal House virtual-pet account through animalhouse.ai. Treat the ah_ token like a password: store it privately, do not paste it into public chats or commit it to files, and rotate it if exposed.

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
