Skill Security Audit

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple review checklist for auditing other skills and does not include code, network calls, persistence, or hidden data access.

Installers should understand that the skill is primarily written in Chinese and intended for auditing skill text supplied by the user. Use it with explicit file inputs and review its findings as advisory rather than automatic security decisions.

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
Confidence
94% confidence
Finding
This markdown file contains user-facing natural-language guidance entirely in Chinese, which effectively forces a specific language for use of the skill. The policy allows locale constraints only when the skill offers user choice or clearly documents a justified region/language limitation, which is not present here.

Vague Triggers

Medium
Confidence
87% confidence
Finding
The manifest description says the skill audits installed skills for several broad categories, including "overscoped triggers," but provides no specific invocation phrases, scope boundaries, or exclusion conditions. In a manifest file, this lack of specificity can make it unclear when the skill should activate versus when general discussion of security or audits should not trigger it.

Natural-Language Policy Violations

Low
Confidence
90% confidence
Finding
The manifest description is written entirely in Chinese, which can imply a language-specific experience without any stated opt-in, alternative locale support, or region-specific justification. This may conflict with language/locale policy expectations when the skill is otherwise not documented as China-specific.
