Happy Hues

Security checks for vulnerabilities and agentic risk

Overview

This skill only helps choose Happy Hues color palettes from a local JSON file and does not request privileged access or run code.

This is reasonable to install if you want palette suggestions. Be aware it may be invoked for fairly broad color-related design requests, so users who only want it for explicit Happy Hues lookups may prefer narrower trigger wording.

A.I.G

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

Finding
The skill trigger description is broad enough to match many generic design and UI-related requests, which can cause this skill to be invoked when the user did not specifically want Happy Hues palette recommendations. Over-broad routing increases the chance of incorrect tool selection, unnecessary file access, and response hijacking within normal design conversations.
