APAG Article Rewriter

Security checks for vulnerabilities and agentic risk

Overview

This skill is a Markdown-only article rewriting guide with no code execution, persistence, credential access, or hidden data flow.

Installers should know this skill is oriented toward APAG-style article rewriting and includes Chinese-language defaults, but the inspected artifacts show no executable behavior, credential handling, persistence, or data exfiltration mechanism.

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

  • 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
Findings (2)

Natural-Language Policy Violations

Medium
Confidence
94% confidence
Finding
The skill's short description and default prompt are written only in Chinese, which implies a fixed language/locale for interaction. There is no indication that users can choose another language or that the Chinese-only behavior is a documented, justified locale constraint.

Natural-Language Policy Violations

Low
Confidence
89% confidence
Finding
Line L141 instructs the skill to 'Prefer natural modern Chinese over translationese when writing Chinese,' which embeds a language/locale preference in the skill behavior. The file does not present this as a user-selectable option or clearly justify it as a region-specific constraint.
