rotifer-guide

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed Rotifer CLI guide skill whose filesystem, command, and network use fit its developer-tool purpose.

Install this only if you intend to use Rotifer. Before running scaffold or publish workflows, note that the Web Studio path can send your prompt and generated source to rotifer.ai, and publishing makes the Gene public; use the local CLI path for private work.

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 is described as a broad entry point that covers onboarding, scaffolding, diagnostics, registry search, and upgrades, but it does not define narrow activation boundaries inside the skill artifact. In combination with powerful permissions such as process execution, filesystem write, and outbound network access, this ambiguity can cause the agent to invoke the skill in situations broader than intended, increasing the chance of unsafe or unexpected actions.
