Copywriting Skill

Security checks for vulnerabilities and agentic risk

Overview

This is a simple copywriting prompt skill with no code, external access, persistence, or privileged behavior.

Installers should treat this as a low-risk content-writing skill. Confirm that Chinese-language instructions are acceptable for the intended users and that broad activation for copywriting requests matches how they want skills invoked.

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

Natural-Language Policy Violations

Medium

Not specified by scanner
Confidence
95% confidence
Finding

The manifest description and all user-facing instructions are presented only in Chinese, with no indication that users may choose another language or locale. This creates a language-policy concern because the skill appears to assume a fixed language without user opt-in or documented justification.

Vague Triggers

Medium
Category

Confidence
90% confidence
Finding

The usage guidance says only to 'tell the AI the type and topic of copy you want created,' which is a very general activation description without explicit trigger phrases, scope limits, or negative examples. This broad wording overlaps with ordinary conversation about writing assistance and could cause unintended invocation of the skill.
