Security checks for vulnerabilities and agentic risk

Overview

This skill is a text-only PRD writing helper with no code execution, persistence, credential access, or hidden data handling.

Installers should treat this as a low-risk writing aid. The main caveat is language: it is designed to produce Chinese PRDs by default, so users expecting English or multilingual output should adjust the prompt or skill instructions.

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

Natural-Language Policy Violations

Medium
Category

Confidence
95% confidence
Finding

The skill hard-codes Chinese output ('help the user design and write a PRD in Chinese') without checking the user's language preference or offering an opt-out. This can override user intent, reduce usability, and in some contexts cause misunderstanding or incorrect downstream use of requirements, though it is not a classic security exploit.

Finding

This markdown file presents all user-facing usage examples exclusively in Chinese. Under the policy rule for language/locale, forcing a single language without opt-in or justification can be a natural-language policy violation.
