Security checks for vulnerabilities and agentic risk

Overview

This is a low-risk writing assistant skill for improving Chinese short-form openings, with no executable code or hidden high-impact behavior found.

Install this if you want Chinese-language short-form opening optimization. Users who need another language should explicitly ask the agent to respond in that language, because the bundled default template is Chinese-focused.

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
Findings (4)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The file states under the default contract to 'Assume the following unless the user says otherwise' and includes 'write in Chinese.' This imposes a language choice by default rather than offering a user opt-in or explicit selection, which matches the language/locale policy violation criteria.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The natural-language instruction begins with "Use $hook-optimizer..." in English even though the skill name and description indicate a Chinese-focused skill. This creates a language-policy concern because the file implicitly fixes the interaction language without offering the user a choice or documenting the constraint.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
97% confidence
Finding

This markdown template is written entirely in Chinese, including the title and section prompts, which implicitly constrains the skill output or usage to a specific language. The file does not offer a language/locale choice or explain why a Chinese-only template is required, which matches the language/locale policy violation criteria.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
93% confidence
Finding

The document is entirely written in Chinese and provides no indication that language choice is optional or that the skill is intentionally limited to Chinese-speaking users. Under the policy rules, forcing a specific language without user opt-in can be a natural-language policy violation.
