Theme Factory Anthropic

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward theme-styling helper that reads bundled theme files and applies a user-selected style to user-provided artifacts.

Before installing, note that the skill may activate for a wide range of styling requests; use it when you specifically want a bundled or custom theme applied to a slide deck, document, report, or HTML artifact.

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 manifest description says the toolkit can style 'slides, docs, reportings, HTML landing pages, etc.' and generate themes for 'any artifact,' but it does not define clear trigger phrases, scope boundaries, or exclusion conditions. This broad wording could overlap with ordinary requests for document help and make it unclear when this skill should activate versus other editing or design skills.
