Security checks for vulnerabilities and agentic risk

Overview

This is a house-advice skill made of Markdown guidance, with no executable code or hidden persistence, though users should be careful with DIY safety and tenant SSN handling.

Before relying on this skill, treat it as general homeowner guidance. Use licensed professionals for electrical, gas, structural, major plumbing, roof, or unsafe repair work, and use compliant tenant-screening services rather than directly collecting or storing SSNs unless you have proper legal, security, retention, and disposal controls.

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
Vulnerability Patterns
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Missing User Warnings

Medium
Confidence
91% confidence
Finding
The DIY repair section gives step-by-step instructions for household maintenance tasks involving tools, fixtures, and plumbing components without basic safety guidance such as shutting off water when appropriate, using PPE, ventilating work areas, or avoiding unsafe tool use. In a home-maintenance skill, users may treat these instructions as actionable advice, increasing the chance of injury or property damage from omissions rather than malicious content.

Missing User Warnings

Medium
Confidence
94% confidence
Finding
The skill instructs landlords to collect full legal name and SSN as part of the application process but gives no guidance on data minimization, secure storage, transmission, retention, or disposal. Because SSNs are highly sensitive identifiers, this omission could lead users to gather and handle applicant PII insecurely, increasing risk of identity theft, privacy violations, and regulatory noncompliance.
