Pixel Art Prompt Builder Skill

Security checks for vulnerabilities and agentic risk

Overview

This is a simple prompt-guidance skill with no executable code, persistence, credential access, or hidden high-impact behavior.

Before installing, understand that this is a lightweight writing/template aid for pixel-art prompt workflows. Avoid pasting secrets or sensitive personal data, and treat the PayPal link as an optional donation link rather than part of the skill's operation.

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 phrases 'structured guidance in the "Art & Assets" area' and 'repeatable prompts the agent can follow' do not clearly distinguish when this specific skill should activate versus more general writing, planning, or art-assistance skills. The file does not provide exclusion conditions or narrower trigger constraints, increasing the chance of unintended invocation.
