Prompt Engineer

Security checks for vulnerabilities and agentic risk

Overview

This is a plain prompt-writing skill with no code execution or data access; its language defaults and bilingual name are disclosed and low impact.

Install this if you want a Chinese-oriented prompt engineering assistant. Specify your desired output language when using it if you do not want Simplified Chinese, and consider renaming it to an ASCII-only or clearly separated display name for marketplace clarity.

A.I.G

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

MCP Tool Poisoning
Confidence
85% confidence
Finding
Mixing characters from multiple Unicode scripts in a single identifier is a common technique to create visually ambiguous tool names.

Natural-Language Policy Violations

Medium
Confidence
95% confidence
Finding
The rule states that unless the user specifies otherwise, generated prompts should default to Simplified Chinese. This imposes a specific language choice by default rather than offering a neutral choice or explicit opt-in, which matches the language/locale policy violation criteria.
