Huo15 Karpathy Guidelines

Security checks for vulnerabilities and agentic risk

Overview

This skill is a Chinese-language coding-guidelines checklist with no evidence of hidden data access, persistence, or unsafe execution.

Before installing, note that the skill may activate on fairly general Chinese phrases about behavior or programming standards, and its guidance/output is primarily Chinese. It does not appear to perform sensitive actions.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • 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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The trigger list includes generic phrases such as "行为规范", "编程规范", and "LLM陷阱" without context constraints or exclusion conditions. In a markdown skill description, these broad terms could match ordinary conversation about coding practices rather than an intentional request to invoke this specific skill.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
75% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Natural-Language Policy Violations

Not specified by scanner
Confidence
95% confidence
Finding

This shell script's title, comments, and emitted checklist are predominantly in Chinese, with no indication that language is selectable or that the skill is intentionally limited to a Chinese-speaking context. Under the policy rule, a skill that imposes a specific language without user opt-in can constitute a locale/language policy violation.
