Security audit

Steve Krug Ux Audit

Security checks for vulnerabilities and agentic risk

Overview

This is a clearly described UX audit skill that tells the agent how to review user-provided websites and does not include code, persistence, credential handling, or hidden behavior.

Install only if you want Codex to perform usability reviews of websites or local web apps. Expect it to open user-supplied pages and capture screenshots/snapshots for the audit, but the inspected artifact does not add executable code or request sensitive system access.

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
