MindStudio Interface Designer Skill

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed MindStudio UI-building guide, with no hidden code execution, data theft, or persistence beyond normal skill installation.

Install this only if you want Claude Code to strongly steer MindStudio Interface Designer UI work. Review generated interfaces before deployment, especially any components that collect files or personal data through MindStudio's bridge.

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

Confidence
97% confidence
Finding

The skill description is scoped so broadly ('every UI/UX request' including creating, improving, reviewing, and refactoring any interface) that it can activate in many contexts without meaningful boundaries. Overly broad activation increases the chance this skill will override more specific or safer task instructions, causing unintended code generation or review behavior across unrelated frontend tasks.

Finding

Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.

Finding

The statement that the skill 'governs every UI/UX task performed via Claude Code through the MindStudio local tunnel' asserts global control without clear opt-in conditions or conflict-resolution rules. In an agent setting, this can create prompt-scope hijacking where this document dominates other instructions, leading to misapplication of the skill and reducing operator control over when specialized guidance should apply.
