Tailwind Design System

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Tailwind design-system guidance package with no executable code, persistence, credential handling, or hidden behavior.

Install only if you want Tailwind design-system guidance to activate for token, theme, variant, dark-mode, responsive, or class-governance work. Expect broad Tailwind-related activation, but the package does not include code execution or sensitive access.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

## Description

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The description says to use the skill when 'designing, implementing, or reviewing' a wide range of Tailwind topics and lists loosely defined 'Chinese triggers' such as 'Tailwind' and 'dark mode'. These terms are broad and common in frontend discussions, and the file does not provide exclusion conditions or negative examples to clarify when the skill should not activate.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The invocation description says to use the skill when "designing, implementing, or reviewing" Tailwind CSS design systems and related topics, which is a very broad condition rather than a narrowly bounded trigger. It does not provide explicit exclusion conditions or negative examples, increasing the chance the skill could be invoked for routine front-end work whenever Tailwind-related terms appear.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
82% confidence
Finding

The package description states that 'Chinese triggers include Tailwind, design Token, component variants, dark mode, class management,' which introduces a language-specific activation policy in natural language. Because this manifest does not indicate user choice or a documented locale-specific scope, it may violate the requirement to avoid forcing a specific language or locale without opt-in.
