Security audit

降龙十八掌

Security checks for vulnerabilities and agentic risk

Overview

This is a simple entertainment skill that generates themed SVG art and classical-style Chinese text, with no hidden code or sensitive access.

Installers should expect this skill to auto-activate on mentions of specific 降龙十八掌 moves and produce stylized Chinese SVG art plus archaic Chinese prose. It does not appear to access private data or make system changes, but users who prefer modern language or fewer automatic activations may want the trigger and style rules narrowed.

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
Findings (4)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The description states that the skill will introduce the move in “古朴文言风格,” which forces a specific linguistic style by default. This is a natural-language policy concern because the file does not offer the user a language or style choice or indicate that this behavior is optional.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger examples include broad phrases like “施展降龙十八掌” and “降龙掌法,” which can match general discussion rather than a clear request to invoke the skill. This can cause unintended activation and irrelevant tool use, though the skill itself is content-generation only and does not access sensitive capabilities.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The activation logic mixes precise move names with broad requests like “展示/介绍/画出降龙十八掌中某一招,” creating ambiguity about when the skill should auto-trigger. In practice this can over-match conversational context and reduce user control, but it is not a high-severity security issue in this entertainment-oriented skill.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The file instructs the skill to output content in “古朴文言风格,” use “文言文/古风汉语,” and “避免现代口语.” This hard-codes a language/register choice instead of offering the user an opt-in or alternative, which violates the stated locale/language policy criteria.
