Ui Design

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small UI mockup prompt wrapper with a documentation/backend mismatch to note, but no evidence of hidden persistence, credential access, exfiltration, or destructive behavior.

Before installing, treat this as a UI image mockup generator rather than a full design-system or wireframe automation tool. Avoid putting confidential product details into prompts unless you trust the underlying image-generation backend used by the local core primitive.

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 metadata and documentation claim a specific capability and service backend (muapi.ai, Atomic Design, wireframes/design systems), but the implementation details describe a different behavior: delegating to a local image-generation primitive to produce a mockup. This mismatch can mislead downstream agents or users into trusting outputs, routing data to an unexpected component, or relying on controls and guarantees that are not actually implemented.
