Brandmark Studio

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent SVG logo and icon design helper with no evidence of hidden execution, data access, persistence, or unsafe authority.

Install this if you want an agent to help generate SVG logos and related brand assets. Review generated SVGs before using them publicly, especially for trademark similarity, brand fit, and accessibility, but the skill itself does not request sensitive access or system-level control.

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

Vague Triggers

Finding

This README is a markdown file, so vague trigger review applies. The phrase 'trigger it naturally' plus examples like 'Make me a logo' and 'Design an app icon' are common-language requests that could overlap with ordinary conversation, and the file does not provide explicit constraints or negative examples to clarify when the skill should or should not activate.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
