Security audit

Data Engineering Interview Coach

Security checks for vulnerabilities and agentic risk

Overview

This is a simple interview-coaching skill with no code execution, credential access, persistence, or hidden data behavior.

Installers should understand that this skill is tailored to a specific persona named Joe and may activate on short SQL or pipeline-practice prompts. It is otherwise a contained coaching prompt with no executable components or privileged access.

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 README says the skill triggers for requests like "quiz me on SQL" and "test my pipeline knowledge," but it does not define clear scope limits or negative examples for when the skill should not activate. These phrases are reasonably understandable yet still broad enough to overlap with general tutoring or Q&A requests outside a dedicated interview-coach context.

Vague Triggers

Low
Category
Not specified by scanner
Confidence
78% confidence
Finding

The sample prompts include short phrases like "quiz me on SQL" that could match common conversational requests and do not explicitly distinguish this skill from broader teaching or coding-help behaviors. Without exclusions or a more domain-specific trigger definition, invocation may be broader than intended.
