Security audit

NoPUA Lite

Security checks for vulnerabilities and agentic risk

Overview

This is a markdown-only coaching skill that encourages persistence and broader investigation, with no code, persistence, credential access, or hidden execution.

Install this if you want the agent to be more persistent and proactive when stuck. Be aware that it nudges the agent to investigate and try alternatives before asking, so for tightly scoped or sensitive tasks you should state explicit limits in your request.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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

Vague Triggers

Finding

The skill declares that it applies to 'all task types' and activates under broad, subjective conditions like being 'stuck' or 'about to give up.' That can cause the skill to override normal task scoping and push the agent into behavior that is inappropriate for sensitive, regulated, or user-bounded contexts, increasing the chance of unsafe autonomy or instruction drift.

Natural-Language Policy Violations

Finding

Large portions of the skill are presented with Chinese headings, quotations, and terminology without stating that the user can choose their preferred language or locale. This may conflict with language/locale policy expectations if the skill steers interaction style toward a specific language without explicit opt-in.
